Carb Kits

[masonf24]

i just purchased some carb kits for my 97 challenger 1800. last week i tried to clean my carbs but when i went to remove them i could not figure out how to seperate them from the throttle and choke cables. i decided to just go ahead and purchase these kits and i figured one of you guys could let me know how to remove the cables. if these carb kits don't fix my acceleration problem then i am going to have to go to the dreaded seadoo mechanics that cost a fortune:ack:


p.s. the guy claims he sells some really hard to find diaphram for the accelerator pump, does this apply to my boat and would you suggest buying this too??? this is my last ditch effort before getting a professional to fix it.

You have the manual for the disassembly, did you check the manual for the connections? The cables just have a 10 mm nut that loosens and than slips off the cable disk, out of the bracket and there out. The choke cable has a small metric allen screw, that you loosen up, and slide the cable stem out.

You might not even need the diaphragms for the carbs if you can clean them and assemble them with out tearing them. Look at the manual and read the section on the fuel section. It has great details on removal and cleaning and then assembly. I'll give you the sections to read, if you can't find them in the manual. Let me know if you need my help. I know if you go to a seadoo dealer it will cost you like 3-$400.00 by the time your done.

Hi Masonf24,
Once the nut is loosened all the way off, pull the cable backwards until the wire is in the hole then it will slide out the side. Once you have the cable free you need to lift it up until it is at 90 degrees then slide the end out of the Throttle lever ass'y.
Keep going you will fix it!!!:hurray:

Accelerator pump...

Yes, your model boat has the accelerator pump. It's on the side of the PTO carb. You'll see one fuel line, about 1/4" in diameter and it leads to the bottom side of the carbs. There is a "T" that splits off the line, one going to the pto carb and the other going over to the mag carb.
Look into the throats of the carb. You'll see a brass jet, about 3/8" long, sticking out into the carb. As you pull back on the throttle, you'll see it squirt gas into the throat.
Why I mention this now is because, if this pump is not working correctly or if one of the jets are stopped up, then you'll have huge acceleration issues. The diaphragm is not hard to find, just expensive. Some places charge as much as $200 bucks for it.
