I have a 2000 srx that when started 2 cylinders are cold. Plugs look wet but no burn on them. I have changed coils out with different ones still not a good spark. I have by passed tors still nothing. I have cleaned the carbs and powervlaves all clean. I look as best as I could for wire harns wear but I couldn't find any. I compression tested it. Gauge was 120 across the borad.

Here's what happened, it was running fine around my yard. I loaded it up let it warm up, trailed it maybe 10 miles with half a tank, ran 2 miles fine no problem and then all of a suden it would back fire and not go above 5000rpm. Put new plugs in when I got home still same problem.

I was reading an old post about the cylinders filling up with gas and flooding them. Should I pull the motor over several times to see if I could dry them out a bit. Sorry for the long post just frustrated. If anybody is near Brighton, Mi. I have rest of week off and wants to stop by and help give me a call at 517-404-6070.

Thank you,
Matt :o| :o|
 
What color is the spark when you pull the engine over with plugs out touching the headbolts??
Be sure to check the flywheel magnets are not all rusted up, you can see them thru the hole above the recoil there, sometimes these get all rusted up from storage and can hamper the signal recieved by the pulser coil.

The next step to look at is the ground wires on the harness.

another thought is the pulser coil wires themselves, have seen them get kinda corroded and then the sled is hard starting or pops sometimes, usually this is one that has rustd magnets on flywheel also.
 
well if its not bright blue spark, you have issues with pulser coil, stator, or coils, then cdi box.

go out and take all the plugs out, put them in the boots, lay on cylinder heads, and then pull it over like your trying to start the sled, they should spark bright blue, if its orangish color, you have weak spark and need to address things I posted about.
 
under the flywheel, behind the recoil case. it bolts on to the case with 2 small allen head bolts.
