I have a pair of 1200's. I had a cylinder repaired in one of my units and now my top speed is only about 42mph where my other ski tops out in the 50s. I have also noticed it does not jump on plain like the other unit.

A few observations (that may or may not be related):
1. I have a small amount of gas/oil in the the bilge.
2. This ski burns much more fuel than the other ski
3. After running the ski for 30 to 40 minutes we have a really hard time getting it started. We have to rapidly trigger the throttle to get it to go. Pulled spark plugs and they look good
4. The machine idles very low 1,000 rps

Any suggestions on what to look at?
