carb adjustment 1993 GTS

[northbay111]

Can someone tell me what that little adjustment is on the left side of the carb, it has stops on either side, can only turn 1/4 turn either way. And is the low adjustment on the right of the carb, the one with a "T" just below the idle screw?

the top is your high speed it should be closed , the T at the bottom is your low speed it should be 1-1/4 out of closed

what about the little adjustment on the left of the carb under the air box?

It is your high speed adjuster and that tab is there to keep you from screwing up the adjustment.

so just to clear things up, the low adjustment with the screwdriver slot and 'T" is on the right side of the carb hidden by the throttle cable device and the high adjustment is on the left side of the carb under the air box and can only be adjusted 1/4 turn either side from center.... right? and it should be closed, turned to the right... right?

I've never seen a carb adjustment like that, where you can only turn it 1/4 turn from center with your fingers. Would have a pic so I can see we're talking about the same adjustment?

Re: carb adjustment 1993 GTS

Why do you need a picture? Go look at your carbs. The adjusters with the limiter caps are the high speed adjusters. Every model of Sea Doo watercraft that uses the SBN carbureators has these limiter caps, as do some other brands of watercraft.
They do not want you to mess up the tuning of your motor. They install the correct main jets at the factory so that the motor cannot run too lean when the adjusters are completely closed. I call them idiot caps. If you need to open them for any reason on a stock watercraft, you need to rebuild the carbs or find out why the motor is not getting fuel from the gas tank, or suffer the consequenses of being labeled an IDIOT!.
