"I just changed out the distributor, put in a Pertronix II electronic ignition, changed plugs and wires.
On turning over, getting a lot of backfires, popping, smoke backing up out of flame arrestor. This goes on for a bunch of turns of the keybut eventually the motor starts running and sounds actually really good at idle in neutral.
When I took it on the water, I couldn't get above 1,200 rpms. If I pushed on the accelerator, the rpms wouldn't increase and I'd start getting a lot of popping and backfiring and sounds like it was ready to stall.
I followed the manual for firing order, Mercruiser Windsor counter rotation, starts 1-8 something going clockwise. And then, running at 1,000 rpms, I hit it with the timing light and have it adjusted to 10 degrees.
Does this sound like firing order is off? Or timing, or both, or something else? Before I redid the ignition, the boat wasn't having these types of symptoms, so it's most likely related to the changes I made to the ignition.
Thanks, Dave"
