Hi all,
I have a 50 B, and I just rebuilt the whole engine as well as the carb. The tractor ran really well at first, but a series of water in gas, then sediment issues led to several tank removals and cleanings. So tonight I got it all put back together, put in about a half gallon of gas, then fired it up. It ran good for a few minutes, then died. I closed the sediment bowl valve, take off fuel line at carb, open valve, and gas rushes out. Okay, I think, clogged carb. I take it off, open it up, and everything is as clean as a whistle. All the jets, everything. The carb needle and seat seem great. Is it possible that a low tank level doesn't have quite the gravity "oomph" to fill up the fuel bowl past the needle and seat?
I have to say it's surprising how small the hole is in the seat part of the needle and seat set. My cruddy tecumseh lawn mower engines have bigger through holes.
Thanks for any experienced comments!
Dave
