I think my squirter might be undersized too.

OK so the bigger sqirter on the primairies may be a little too much. The hesitation problem is gone, but now it seems to be flooding again. . .

Any suggestions?

I recently swapped out my carb and it was also having the occasional hesitation going from idle and giving it some gas. Turned out I had to adjust my throttle cable a little bit more. Not sure if that will help your problem or not. One other possibility I can think of might be your timing.

Could you comment in a little more detail about how you adjusted the cable to remove hesitation? Thanks.

I will try although it is easier with pics, I just dropped the boat off this morning for an oil change. I managed to find an old pic of the old carb, as you look at the picture, on the right side of the carb as you look at it, you should see the linkage I am talking about, red shield over it. Where that meets the carb is the linkage. Disconnect that and look for any disparity between the idle position on the carb and the idle position for the throttle cable. There is a small nut and the linkage that are threaded on that. Adjust as necessary but make sure to tighten the backing nut when you have it adjusted properly. If you cannot get it right, the bracket that holds the throttle cable can be removed and I drilled holes to move that bracket right to where I needed it.

Ok, I know I said I had the pic, but right now I am having issues getting it to upload. I will try again later.

25 to 32 is a HUGE jump. 2-3 sizes in a single change at most. 32 your lean stumble will be gone but likely replaced with a rich bog. It'll just feel down on power, waste gas, and likely have a dark or whitish smoke out the exhaust on quick acceleration. Also going too big on the discharge nozzle you may need to swap the 30cc pump for a 50cc pump to avoid a lean stumble at a higher RPM or throttle opening. But runnig a larger pump, discharge nozzle, or pump cam than necessary will waste a lot of gas especially if you have riders that fall a lot.

Well, we'll see what happens. I can always change the squirter if necessary. I think my latest problem had to do with inproperly adjusted float on the primary bowl. The guy that rebuilt the carb did not know of the angle at which the motor is mounted and I think we leaked fuel through the venturi's last time out. The boat ran great at first, then we stopped to eat and threw out anchor. While anchored we hooked to the back of another boat (stern-to-stern) and everyone in my boat ended up sitting the rear, so the motor was probably sitting at about 20+ degrees for about 40 mins. When I went to start the boat I could smell fuel pretty strong so I knew it was flooded again.

I took the carburetor back to the shop today and Cleo (55 Chevy Rat Rod), my carburetor mechanic, lowered the primary float. Also I talked to Vince at skidim and got his .02 cents on making adjustments. Tomorrow night we'll go on another trial run to see if we did any good . . .

Considering getting a 12 degree wedge plate from Holley if we cam't get it work any other way.

I think we finally got a combination on the carburetor that works - yay!

We lowered the primary float so that it has less tendancy to flood. Ran the boat through its paces last night then shut down and let it sit for a while to see if it would start easily and it did great! I also replaced all the spark plugs because I think they got fouled last time it flooded so bad.

The bad news - when my son and I went out for the trial run we only figured on a boat ride, not wakeboarding so we didn't take any of the boards. Check out how smooth the water is in the pics - we were the only ones on the river and it was glass. Figures.

Congrats Clint. Glad you got it figured out. I never get tired of seeing pics of your boat or motor.

Thanks Titan and others for the comments and compliments. . . I love my boat!

Phase 2 of my Sunsport project is nearly complete with the exception of some wiring and general tidying-up. Yeah, yeah, I know, you never really get finished . . .

Last night I re-packed the wheel bearings on my trailer and came to the conclusion that I would like to make one more modification to my trailer. That is to replace the tandem 3500# axles with a single 6000# axle with 16" tires and wheels - and use an ez-lube axle with spindles drilled for lubricating both inner and outer bearings. I'm sure I could sell my tandems without any trouble.
