Re: 1986 Marathon. No power unless muffler removed
I just checked the timing using an inductive light and forward timing is lining up on the mark just a little to the right but the reverse timing is so far off it’s maybe 4 inches to the left of the mark. What would cause this? This would indicate the timing being retarded which would explain the very slow acceleration and higher top end power.
EDIT: pulsar coil is reading 156 ohms. Secondary coil orange to green reads 4.5 ohms and secondary orange wire to plug boot is 11k ohms. All within range. How can the ignition timing in reverse be far off when setting one direction correctly automatically puts the other in range.
