Ask Your Own Small Engine Question

This being a twin engine, have you ran a cylinder test? Loosen the spark plug wires and with engine running, remove one wire at a time, to see if both cylinders are equal. If engine dies when one wire is removed, the opposite cylinder is not firing. If that is the case, check compression and check the valves, and check for park, even though as you have already replaced the coil.

Compression is good bothe above 150 psi
Customer reply replied 8 months ago
I have adjusted the valves

Did you run the cylinder test? If cylinders are ok, then you have a fuel starvation problem, and the surge is being caused by a lack of fuel, and the governor trying to compensate.

Is there any kind of measurement for a fuel delivery it takes a while for it to act up and I have replaced the electric fuel pump already

You would have to measure fuel when it is acting up, Or make a test line and run it direct from your fuel pump, into a separate fuel tank. Bypassing the existing fuel tank and hoses up to the electric pump.
