Hi all, my sons jet ski set for several year and would not start. The issue was the carburetors were gummed up. I have cleaned and rebuilt the carbs, checked the pop-off pressure (ok) rest them to factor specs. checked the factor fuel pumps (5psi) good fuel flow. All the fuel lines are replaced. The gas tank has been drained and has new fuel.

Here is the issue: When out of the water it idles good and has good throttle response, when in the water idles just fine but when giving it throttle it bogs down like it is starving for fuel. If I hold the chock out about halfway while giving it throttle it gets up and goes but if I let the chock go it bogs down and wont run.

Question, should I be adjust the low speed adjustment out ( I have done this about a half turn 1/8 and a time and does not seem to help or do I need to go further. The high speed I have adjust a little but not much.

Like I said it runs great as long as I hold the chock halfway.
