It was running last year, John Penny is the owner and a nice guy but runs it as a sideline. Join the Armstrong/CCM trials group on facebook and ask the question there, it's a useful source of information too
I wouldn't bother. From experience the weight is more suited to none clutch use as it prevents the engine stalling. When I firtted the electronis ignition to my greeves trials bike, I left the weight off thinking being used to riding bikes with virtually none I would be fine, but it was almost unrideable. I was gutted to have to add over a kilo of weight to the bike as I've spent a lot of time and effort reducing it's overall mass
My experience with small bikes suggests the carb could still be blocked, the jets are tiny and take some clearing out as do the airways in the carb itself. Also if it has a dellorto carb, these often have 2 slow running jets in the same boss. i think your clutch issue is just that this bike could have come with a centrifugal clutch from new
I can't see clearly from the photos, but are you sure the tyres are seated on the rim correctly it looks like the bead might still be off the rim and in the centre depression. It's common with off road tyres that they don't want to come back on the rim properly and you have to deflate soap up the bead then reinflate even as high as 80PSI
I did a couple of trials back in the late 70's on my 185B but they were too hard (no dual routes in those days) but I did a lot of practicing with my brothers who had similar trail bikes. Yes the power comes in strong about 4500RPM but usually I kept it out of that. Dropping the barrel a little more might help and , like you say the compression is quite low. My B model had higher compression and the later models dropped it each time.
I've just bought a C model which has stood outside for the last couple of years and nearly have it back on the road.
Have you any parts left over would love an exhaust and tank like yours and I'm short of the air cleaner assembly
False. That gearing will be fine, if you do need a higher gear you will find second is more useable. Chances are though that it will jump out of either gear
Most of what you want should be available from John Penny at Armstrong Trials, he has a web site but it does not appear to have changed for a while so should give him a ring
To see how you like it (or otherwise) try removing the footrests and bolting them on the outside of the bottom part of the hanger. If good you can normaly fabricate a new part for the bottom bit and bolt it on. Have done this on my Armstrong and the brothers Fantic
If the gearbox is the Albion one, your options will probably be limited. For multilap closed circuit trials the 3 speed villiers box is probably better as it's narrower and you can change the ratios with parts from villiers services Adapting to the later villiers 4-speed box is possible, but not easy
I went with my brothers, and although there were empty spaces we felt it was worth the trip. I think the parking fee is not too bad, most people seem to be 3 or 4 up too so only a £1 per person.
Know someone who used to work for the Telford International and he says thay have put up there fees greatly

Not on a modern bike, but I use it in my Greeves as it did have a tendency to seize and it's the most tenacious of oils.
