What happens if you pump the primer bulb ??
If she runs better with cowl off,sounds like possible exhaust fumes are being reintroduced into carb. thus poor running
Thanks Johnny, does it effect fuel flow with the smaller filter or does not matter.The ten micron will filter out smaller particles
There should be a strainer in the fuel tank and in the fuel pump. Not a big fan of inline filters these engines have been running good for over 30 years without them.
