Well the issue is that the ski breaks up after riding for a bit. It usually takes about 1/8 thank of gas for the issue to surface. It feels like the revlimiter is kicking in when you smash the throttle. The ski runs fine when brought to high RPM slowly. Carbs are in tune. I was starting to have this problem at the end of last season but thought it to be due to detionation loosining my spark plugs. Since then I have switched out my stator / flywheel with a 62t (Was using 61X) Therefore, I am going to rule out the stator. I have not heard any complaints from the person I traded with as well. I was running an MSD coil wiht people said was most likely the problem. I since swapped that out with a stock coil (Unknown Condition) and the issue remained. I tried swapping in a stock CDI instead of the MSD Enhancer and the issue is the worst it has been. Therefore, I feel its the coil. If people have other suggestions any input is apprecieated.
Before installing a bunch of parts you should check the resistance of the ignition coil and stator pulser coil.
Just use an ohm meter with the coil disconnected and measures the primary resistance across the orange and black wires; it should be between .078 to .106 ohms at 68F degrees.
Also check the secondary resistance across both spark plug high tension leads and it should be 3.5 to 4.7 ohms at 68F degrees.
To check the pulser coil on the stator just unplug the white/red wire and black ground wire; it should be between 12.6 to 15.4 ohms at 68F degrees.
You should also check the spark plug gap width and resistance if they have built in resistors and should measure less then 6000 ohms.
It's pretty common for spark plug wire ends, spark plugs and pulser coil wires & windings to go bad and if they're out of spec replace only the parts that are needed.
