I've been repairing our old gasoline 50 that we've had since the 1960's and has sat many years. I've had it running in the shop a few times testing and repairing various components like hydraulic lift, pto, waterpump, etc. I finally got everything put together well enough to test it out yesterday. Ran it around the yard and tried all the gears. Seemed to run okay but it you revved up the throttle too quickly it would only run on one cylinder. I tried fine tuning the carb adjustments but didn't make a difference. I tried moving timing back and forth a bit on the magneto and didn't see a difference but then the tractor started running worse and wanting to die. It will almost start at a slow idle once in a while. Now it backfires everytime I try to start it. I've just got a car muffler sitting on the pipe and the backfires have blown it up like a balloon. I ran a compression test and each cylinder has over a 100 pounds.
I switched to a propane carb. which I have run this tractor on before and the backfire / not starting issue stays the same.
I have a strong spark at both plugs, but I am thinking I should order a new condenser, points and rotor.
Could my magneto have skipped a tooth? I only loosened it enough to advance and retard it.
Thanks
