I have good compression and strong spark on all 4 cylinders yet i have rough idle and very poor top speed. I tested the coils, trigger wires and stator wires with an ohms meter and all are in spec. I marked TDC of each cylinder on the flywheel 1,2,3 and 4 respectively and hooked up a timing light the results have puzzled me
when timing light is set on clylinder 1 i see that both 1 and 2 are firing. on cylinder 2, 1&2 are firing again, on cylinder 3, 3&4 are firing and on cylinder 4, 3&4 are firing again. is this normal ?
