Light acceleration misfire?
My 440 runs quite well except for two issues: horrifying mileage and a misfire under light acceleration. They may be intertwined.
The 440 is a KRE 85cc headed 400 with 4" stroke and 0.065 overbore.
Mild roller cam with Edelbrock ProFlow 4 fuel injection. I suspect electrical gremlins, perhaps coil? Engine idles rock steady - though timing varies 2-3 degrees, not sure if this is due to a mediocre timing light or other issue.
