Hi Bob the push mower is a Quantum 55 motor. I reckon you are on the money with the fuel cap call.

For the record the tank carb height difference is greater on the ride on and chipper than the push mower.

I have switched to the red Briggs filter and they have run perfectly so I'll stick with them. The problematic filters did seem to collect a lot of fine particles that the others let through.
