On my 76' T140, the kickstarter will get stuck on the way down once every 50 kicks. I do let it back up and it will be fine again. I don't think it has to do with a stuck clutch but something to do with the wear of the kickstarter engaging gears ?
I found here a great explanation on what gives and how to fix it, but can't find the thread anymore

Any idea ?
Thanks.
Terry
