Carborator Set Screws

[yamahaman101]

Ok now that I have compression at 120 psi in each cylinder can someone tell me how the set screws work? If I turn the low set screw in does it feed less fuel and bog it down and if I turn the screw out is speeds up the idle? Also what is the purpose of the high screw? Air intake? If so how should I set this one?

You need to list you seadoo information in you avatar on you seadoo...year and model. Typically the Low Speed screw is set at 1 1/2 turns out...and the high Speed screw is set at "0"

First of all thank you for your understanding on the question being sent directly to you. Is it true that I am only to have one Low Set Screw? Thank you again!

Yes, each carb has 1 low speed screw...and 1 High speed screw...the high speed screw has a plastic cover on it to so it can only be adjusted out 1/4 turn more...but it is really needed. be sure both carbs are in sync. Uh...what year GTX is it...look at my avatar for an example of what you should. It's best so myself and other members will know exactly what seadoo you have...I answer at least 75-100 posts aday...If I don't see all the information...I pass on to the next problem...Let me know if you need any more help.
