I bought a 2001 Sea Doo 2000 Challenger and it smokes alot at Idle speed. I have ran fuel injector cleaner through it and it has helped a little. My question is can you adjust the oil injector up or down? or is it automatic? If you can where is the adjustment? Any help would be great! The boat does not smoke at all when I am moving along but when I am going through a no wake zone or start it up for the first time it is pretty smokey> Thanks in advance.
