[Farmall] Troubleshooting no start

[birddog]

Another thought, Dean.  If the dirty air cleaner was restricting the air 
flow, the carb may be adjusted very lean to compensate.  Try hooking the 
cleaner pipe back on.  At least it can prevent burning the barn down if 
she backfires.

Charlie  Good luck again.
