Hi I am currently using stock setup supplied with my 26 mm o k o which I bought in the UK after extensive searching on the net to find a genuine Taiwan made carb not a Chinese copy ( I'm sure you've heard the horror stories ) currently fitted with 112 main jet k44 needle and 45 pilot jet but after getting some great advice from Roger at atlantictrials.com I am waiting for a new needle which is a jjh type and I am going up 2 sizes on pilot which is a 50 pilot so will try these and post my findings when fitted.if you need setup advice Atlantic trials are o k o gurus so speak to them if your having problems they are very helpful.I set my timing to 2.75 btdc after recommendations on here from members and is spot on now . Good luck regards Darren

Thanks for all you advice especially the beers they helped.found out the problem today with the help of a friend at work with a good dial gauge to check my attempt at setting with basic plug gauge.I was using a cut out centre from a spare generator flywheel the same type and part number just to have more access to points.so checked and reset to get 2.75 btdc then fitted my generator an rechecked setting found that I now had 0.4 mm btdc well retarded and that's including me !!! turns out wear on cam centre on cut out tool causing the problem reset the timing the fiddly way through Windows in flywheel I was using taking on and off to tweak stator plate to my 2.75 setting and bike fired up first time so all sorted just waiting for my new needle and bigger pilot jet for my o k o carb and then it's getting dirty. Thanks again this is a great forum.

Hi I am a new member to this site and need some advice on setting my points ignition timing on my 1976 350 sherpa.after reading above thread from mudferret posted in 2012 I have exactly the same problem with my timing when I set timing to 3 mm btdc my stator is fully advanced (fully clockwise) with no more slot to adjust further I am aiming to achieve 2.75 mm btdc so I don't get why the stator is this far advanced all ready.I am using Tdc plug gauge and I have a test light to check when points are breaking I also have the centre out of a spare flywheel to aid in points setting.if anyone has advice it would be appreciated I am pulling my hair out. Regards Darren

Hi I am a. Swindon member with a problem setting my ignition timing on my newly rebuilt 1976 350 sherpa.I have set up timing on other bikes before but am losing the plot with this one.I am trying to get my timing to 2.75 mm btc using a spark plug gauge ant test light to show when points are open.but I can only get to 3 mm there or there abouts ant that is with stator plate fully advanced (fully clockwise with no more slot left) am I doing somthing wrong as needing more advance when I am all ready at full adjust seems wrong ? Read a post on here recently from a member called mudferrett with the identical problem but can't find the out come of his post after listing his problem. Any help or advice greatly appreciated losing the plot at the moment !!!!!!##!#
