What’s the most likely source of a sporadic idle and loss of WOT?
This is a 1994-ish motor, SN starts with OG002.
Both cylinders measured approx 115psi (which seems low to me).
Digital tach shows max of about 5200 RPM and 22mph.
I ran a mix of Seafoam in 1-1/2 gal to try cleaning out carbon. No real change in performance.
Performance is similar with each spark plug unplugged.
