CV22s

Old CV22s. 80s.
Pulled it out after winter. Started fine. No power. Replaced carburetor, no change.
Found a chewed plug wire. Replaced both coils.
Would not pull normal rpms. 2000 and sounded like there was a load on the engine.

Disconnected the pump, got to 2400 rpm at full throttle. Still sounds like there is a load on the engine. PTO clutch is not engaged.

Mower ran fine last year. Compression is 155 in one cylinder, 160 in the other.

Seems like it had something to do with replacing the coil packs. Air gap .010.
