FL250 won't start
« on: March 31, 2020, 11:29:51 AM »
Hello team-

I have a 1982 FL250 that wont't start. It ran like a champ until about a year ago when my brother was out riding it and hit a bump knocking the battery off. After that I couldn't get it started but just figured he had pulled a ground loose so I parked it meaning to get back to it.

This FL250 has a racing head that is water cooled and a Goki starter. I just had the started rebuilt. Since it sat for a year I drained the gas, replaced the fuel filter, disassembled and cleaned the carb, and replaced the fuel filter. Thinking it may have been a clogged exhaust, I removed the exhaust but am still getting the same result. Spark is good and blue, with a new spark plug. It won't fire, even if I put starter fluid directly into the cylinder. Compression is 150 PSI. Not so much as even a cough when I press the start button.

Any ideas/suggestions as to what to troubleshoot next?

UPDATE:  A couple of backfires, now gas is leaking from one of the overflow tubes.

UPDATE 2: It was the carb. Swapped it out with a spare and she's purring like a kitten now ;)

After I started her up I noticed some plastic pieces flopping around below the drive pulley, and the drive pulley is loose. The bolt that holds the drive pulley on just spins. What next?

Managed to get that screw tightened, but now the weight won't move when I hit the gas, so the clutch never grabs the drive belt.

Anyone?

I'm guessing that's not the stock clutch...  At least it looks different than mine. After looking at the: Drive pulley itself: picture showing it spread with the spring, the only suggestion I have is to see if you can pop it back in. When testing mine without the belt on I had to pop mine back out.
