Had the ten out over the weekend and she ran nicely over the 100 or so miles I’ve covered. Even repeated the same journey as the one it seized on a few weeks back and no problems.
Here’s what I found between then and now; the fuel flow was fine from the taps, but the points gap had closed from 12 thou to 8 thou retarding the ignition. So reset that, did oil n filter change, flushed out the tank and lines, (made new seat brackets while waiting for a filter to arrive), stripped the carb and blew out and cleaned all the jets and stuff and fitted a new throttle spring that is forgotten I’d bought. Found the cause of the sticking throttle to be the new twist grip was binding on my cheap-ass bar end mirror, so trimmed a couple of mm off the end of the rubber grip, and along with the stiffer spring now feels way better. Checked and reset the valve clearances, changed the fuel filters and made better lines, checked as many bolts as I could get to.
Going up the same hill as last time, she started to slow a bit (55 down to 50, but that was near the top of the hill and by the time I’d thought about changing down a cog wenwere levelling out and starting to accelerate again. Yay!
With regards to the points gap; I initially thought that the points had slipped, but on closer examination I notice that the fluffy thing that oils the cam ring is missing so possible that the lack of lubrication had caused the heel of the points to wear, thus closing the gap. I’ve given the cam ring a smear of grease to help ease the points on their way.
Ive ordered a new carb kit from Amal along with the next couple of size up main and needle jets, though to be honest, I don’t think it’s far from right now anyway.
Thanks so much to all here for the advice and help: you guys rock!
Peace!
