Hey guys. new to the forum, I just bought a Seadoo Challenger 1800 a few weeks back, it has the twin 787 Rotax engines, was running great and all was well, but after the last time I took it out on the water, it started Backfiring at low idle on the passenger side engine. I tried the following:
Swapped Carbs
Swapped Rectifiers
Swapped Ignition Boxes
Replaced Stator
Checked Rotary Valve Timing
I'm not sure what else it could be. I heard possible sheared key or ignition timing but im not sure how to check / adjust either of those things. Any other further ideas guys?
