Another fuel starvation issue (help?)
Posted: Sat Dec 21, 2013 5:16 pm
Hi all,
Having fuel issues with my 1958 Lo-boy. The machine has it's original tank, sediment bowl, and carburetor. Currently has a see through Briggs& Stratton in line fuel filter. The machine has been starving for fuel lately, as evidenced by the fact that I only get a piddle of fuel coming into the fuel filter. Initially thinking it was a sediment/strainer issue, I took sediment bowl off, cleaned bowl and strainer, and put it back together. No dice, If I start the tractor up with choke closed, it will "pull" enough fuel into the bowl to stay running at about 3/4 choke. With choke off, VERY little if any fuel getting into filter. Today I pulled carb off, cleaned the main jet and needle/seat, etc..., and set the float level at 1 13/32", with 3/16" drop. (steel tipped needle btw). Still no dice, WORSE if anything. I've seen issues here where some in line filters seem to have flow issues in these gravity systems, but the filter is new and I seem to get plenty of fuel "free flowing" out of it. Suggestions please????...Also- tractor will run with idle mix screw all the way in. Maybe that help the diagnosis??. Thanks in advance,
Sam.
