Okay guys, somewhat new to the stand up jetskis world, I purchased 2 of them. My 550 runs top notch.
I cant get these Dual Carbs tuned right, I had it one point but had to remove the carbs to repair other stuff and then the screws got messed up.
91 750SX Keihin Sudco 42mm Dual Carbs
Full Mariner Exhaust
R&D Racing Head
40:1 Fuel Mixture
I can get the low end going, not enough to stand up, but anything over half throttle gives me no extra response, and it just pours smoke. Once I get it started, it will go half throttle and then it will die about 20 seconds in, then wont start unless you let it sit for 10-15 minutes.
Any tips? Help? When do I know to stop tuning the front carb and then start on the rear? Should they be the same turns for both? More air? More fuel? Im at a loss, I can tune a single carb but I cannot figure out these duals..
Thanks for all the help!
