This is a little long but here it goes.
I installed a new trigger coil, bracket broke on original. Next time out ran about a hour at WOT with no problem.
Filled gas up, headed back out and took a WOT high speed hard left turn and engine stumbled. Took same type turn to right, no problem. Took another WOT hard left and engine bogged even more. Headed back to ramp. At WOT, RPM was down to 6600 instead of usual 6900. Eased back to low speed for rest of trip and no problem with engine.
My compression tester was leaking air so no reliable reading. I removed head. No scoring or detonation seen. Inspected OEM fuel filter, it was OK. Secondary stone type fuel filter appeared to have some clogging. Removed carbs and inspected internal filters, they were clear.
I know that left turns load the engine the greatest. Bog there could be from lean condition. I'm going to clean carbs, replace external fuel filter.
I'm trying not to inspect under mag cover unless I have to. Does this sound like it could be an electrical problem relating to my installation of the coil? Any suggestions on additional diagnostics.
Thanks
Jim
