I have been working on a Cockshutt 30 for a few months trying to get it running good enough so I can trust it on a joy ride without it stopping and me walking back home.
The gas tank cap leaks when tank is anywhere near full. I added a gasket I cut from gasket material and it no longer leaks. Cap fits on real tight.
Question I have is I think now the cap with the gasket makes for an air-tight covering. I have driven the tractor for 20 minutes so far (wide open) and it runs flawlessly. The question I have is "does that tank need air coming in as the motor runs?"
My Farmall H needs air coming in to run, or it will stop after a while, starved for fuel.
