Surging Problems with 1987 125hp Force
Has weak fire on upper 2 coils. Surges when running. I have checked the compression and the spark on the plugs. Can anyone help me diagnose this problem?

Surging indicates a fuel supply problem. Start there.

This could cause the firing on upper coils to be weak?
