Re: Engine Misfire & Stumble

Update!

Just checked the fuel pressure, filter, and replaced line at carb. Filter is in place between pump and carb. Should I have more pressure under a hard rev in park?

Fuel Pressure, 5-6 at idle, drops to 4 under hard throttle in Park.

New thoughts? Checking Coil and Pick up Coil assembly, will update later.

Checked the Coil, and Pick up Coil assembly, both check within spec.

Noticed timing chain has about 2 degress of slop. Performed this check by simply turning the fan. Any thought on that?

Only have 70k on that gear and chain as it was a complete top end rebuild 8 years ago.
