Guys at last getting somewhere , two steps forward and one giant leap backwards , today took the unusal step of getting my "old" LT coil back from the supplier [yes gave them theirs back] and then re-treated the damaged / bared windings with some fresh nail varnish [jesssssssss does that stuff stink] , checked the black - green Ohmns reading 2.1 not sure if thats correct but least its not a short ! Re-fitted back onto stator plate , checked points do break contact ok , timed ignition 2.6mm BTDC [even though manual says 3, will change later] , re-connected Black wire to HT , Green to HT mount , plug on side of case & throw the switch [kickstart] ... A SPARK !!! So after all this it looks like my original LT coil maybe ok , I stress the "maybe" , because I've still not been able to get the bike to start but this is a move forward and proves the "new" LT coil was shot and has had me going round in circles !! Now I need to check to see if the spark I have , which I think should be ok ... IS OK ! If John or Dave are reading this , guys anychance you can put an Ohm meter accross the black n green wires , would love to know if my 2.1 reading is good, bad or there abouts ! Ok, now I've just got to kick-back n wait for my new carb to arrive , left Miami yesterday , hopefully it will bring some Florida sunshine with it ! All best , Greg BIG PS ,,,,,, what would happen if I removed the lighting coil , put another LT coil in its place , wired it in with the existing one [so it switched with the one set of points] and had two LT outputs feeding the one HT coil ? ,,,, no not mad just curious lol PPS , when i get the bike running will move the condensor as per the "old bultaco trick" lol

I just dont think I can go threw all this hassle again ! To John , Dave and others that have rattled their brains over this one , I really do appreciate it and hope to report soon that alls well and am dabbing away like billy-oh in the sections ! All best Greg

Mmmm not sure why the first has a different URL but hey , thats what I had & thats what I have now ! Dave , am confused [easy i know] but why have you moved the condensor ? ..surely the shorter the wiring the better ? Cheers Greg

Well thats it John .... whats the verdict ? .... so hope I've checked it the right way lol All best Greg

Hi Dave Its ok I have a cunning plan , am going to enter the next meeting and at the start [when the bike wont start] ask for assistance from as many Bultaco riders there lol ........ hopefully by the end of the event I'll have a working machine As for posting a pic , lovely idea but there really is'nt much to post .... just done the "check the spark in the dark" test & confirmed my previous post ... Ta Greg

Ok John , going by theeeee book and your kind words .... If I connect the black wire to the LT side of the HT Coil , I get a weak spark ! If I connect the red wire to the LT side of the HT Coil , I get a better spark than the above ! Odviously this is not correct and now I have a new "wont start" suspect , the already replaced LT coil or something else in the electrical system , but nearly all of it has been replaced ,,, appart from the HT coil . Jesss will it ever end ! All best Greg I know it should make NO difference but how many people have gone over to a digital system ?

Thanks John , right on it this week , daft question but i presume when the buld goes out that when it should be 2.5-2.7mm BTDC ? ..yes ! All best & thanks a lot ! Greg

Quick question John , how would the kill switch been wired using the standard colour system ...just incase i have mine ass about face ....and is the voltage coming off the black wire [to ht] the same as the red wire [rear brake light] ? Cheers again , Greg

The bike ran for a few seconds then fowled the plug major league , but when the crank is full of clutch oil & petrol thats not surprising [crank case seals in wrong way & totally shot] ... so me being foolish believed the "its the old petrol" excuse #310 and bought it as a runner when clearly it was not ... big big leason learnt here , make sure the bike runs for a minimum of 10 mins , you get a proper test ride to check all gears and dont believe anything your told ...even if it is your DREAM bike ! When I got it home , it ran for another few mins [major smoke] and after that it came appart ! ,,,, am so convinced its the carb , as nothing & i mean nothing ties in with the spec for a VM26 taken from the pro-flow.com chart ! which is why in a depressed state i ordered a new VM26-74 from the US .... this time next week and i hope to be posting a different thread ! Guys , thanks for all the help , like you say this is such a basic engine and should be easy to problem solve BUT only if the parts are good to start with ! All best Greg

I would love to think that might solve the problem , but its deeper than that maybe the carb is as shagged & cobbleded together as the engine was ...only saving grace was that the previous owner never got it running either which is why its still on its "first" yes first original std size piston ! Am going to try a new trick tommorrw , hold a blow-torch by the carb mouth , if it sucks it in and fires great , if it does'nt n sets fire to the bloody thing , then i'll stand back n warm my hands !!! Cheers Greg

Hi Neo , am just wondered what made you think of the change ? ...am thinking my non-starting issues maybe down to the carb and looking to either a new Mikuni or Dellorto .... but can I find any concrete facts at to which is better or easier to problem solve ..let me know how you get on all best Greg

Well after rebuilding my 198 Bultaco engine [all new seals etc] and spending the last week carefully putting it back together and not even rushing the final assy today , the bloody thing still wont run ..... not a back-fire ...nothing ... zipppp ! Plenty of spark , fuel is there and am annoyed / fed-up / going back to 4-stroke & leccy start as soon as I get this bloody lemon going ! If anyone knows the ins/out of a Bultaco engine and can help , even if its "try this carb" I would be so happy to hear from you , am more than happy to bring the bike over to your garage ! Other than that , constructive comments apprecaited ! Going down the pub , Ta Greg

Alt , I have a Miller Hi-Boy frame if you need pics to compaire , I was in the same boat a few weeks ago thought I'd bought some mystery bike and sent images over to Sammy Miller & he confirmed it was a Miller frame [thank god] ...there was a thread i started in the classic pages ...might be some old info there ...any help just holla .. All best Greg

F1 ...whats that ? Enough Said lol Greg

Guys , after spending ages cleaning all the nasty flakey paint off my Ali cases , question is , do I re-paint* them or leave them clean ? Would hate the engine to look like it was a few years down the road ... Cheers Greg [getting there] Ps, * if its Paint them , whats the best paint / process for success and longevity !

Anyone got any ideas for cleaning the years of oily gunk outta exhaust systems ... have time on my hands so it can soak fill with BRAND X ? if needs be .... cheers Greg

Probably because at that age , if anyone told me any of the top flights used it ..then I rushed out o buy it ... anyone need some bright YELLOW fantic pants ? ...am sure a work rider whore them in the British lol Love the dishwasher idea though ... must remember to allow for that in the kitchen re-fit ...but thats only if the engine rebuild does'nt sink all the money first ! Laters Greg

Jizer for engine n oily parts ... was using Mer [blue bottle] for splash n dash on the rest of the cycle parts ...for plastics when dry use Mr Sheen ! Greg

Wicked ..just come in from the garage to make sure "Eastenders" is turned OFF .. had a right laugh .. Q. Will I be able to use the George Forman to Aneal the copper head gasket or must it go in the over at Gas Mark 3 for thirty minutes ? Just thought of another one ... Those wizzie vibrating toothbrushes would make great fin cleaners , especially right in between ... not suggesting you should nick the other halfs or the kids but it has more than just one use ! Will check back later for another laugh ... Eastenders off , back to the garage to polish my piston lol All best Greg Ps, ****ing typical just ordered a workshop manual from Dave @ Bultaco UK and now theres a ****ing Post Strike grrrrrrrrrrrrrrrr !

Hi Guys Just a funny thread to keep the sprits up ... whats the funniest or most bother you got in , using the other halfs kitchen [or mums] to help prepare or fix your bike ? Mine , was the look on my mums face , when she came back from shopping to see a pan of black oilly goo on the cooker and me trying to lower a chain into it ... yes you've got it ... good olde "Link Life" ..what ever happened to that ! ... did I get it in the neck or what ... almost as much trouble as getting caught in the bathroom using the shower to spray the "Gunk" off my frame ... thinking back , what was I thinking ...should have been using Jizzer LOL , Come on lads lets here those "crankcase in the oven" classics ... All best Greg Ps, Is it true a dishwasher makes a wicked engine cleaner ?

Cheers John , its got a lot worse this this post , engine now in a 1000 parts , reason , crank seals are completely shot ! .. looks like Dave & Co are gonna have a good christmass lol Ps, thanks for all you help so far ... I ow you a few beers already !

Guys Just courious , what would happen if you swopped your VM26 Mikuni for a slightly bigger VM28 Mikuni carb ? Cheers Greg Reason for question I can buy a 28 for a lot cheaper than a 26 ... and then jet to suit !
