96 xp carb ?

[glsmohio]

ok i reset the high and low to where they should be (PO HAD IT WAY OUT OF WACK). ski starts off and idles good but when you give it gas it falls right on its face. if i goose it 3-4 times it will pull right out of the water and get it like dale jr! What am i missing? should i run some sea foam through it?

thanks guys

high at 0

lows out 1

No, NO SEAFOAM!

Little more info please...
What have you done so far to the fuel system?

why no seafoam?

carbs have been rebuild, pop off good, new fuel lines, new filter...its had the works.

thanks again

The reason I say no Seafoam is that there is nothing in the PWC fuel system that it can help. It will not clean anything as you know these fuel systems need to be rebuilt with new parts.
Seafoam is a solvent and can harden the rubber and plastic parts like the fuel pump diaphragms and seals.
In addition Seafoam being a solvent can actually strip off the 2 stroke oil film that lubricates your pistons and bearings.

The only thing I would suggest adding to your fuel is a stabilizer for winter storage.

I'm not saying I would use it but, their website claims its safe for seals (not living seals) and 2 strokes and can be used as a fuel stabilizer. They even give instruction on how to use it in a 2 stroke. AGAIN......I'm not saying I would use it. Just posting what THEY say. Again....their words NOT MINE, I'm not their scientist or salesman. And just in case you missed it, I in no way would support or use it, just posting for reference purpose.

Thanks racer, "THEY" also say ethanol will not harm anything either. HAHA.

So any thing you guys can think of that i might need to look for? Maybe i should take the carbs all apart and get one of those cleaners from hf to put them in?

Turn the two low speed needles out another 1/4 to 1/2 each and try it again. Make sure your testing it with the stock flame arrester cause it will have a lean bog without it.

Matt when I was testing it I had the stock flame arrested off ( so I could set the idle) would that cause the problem?

 

[mikidymac]

Matt will chime in but not having the stock arrrestor on will cause a big problem. Jetting will be off and the vacuum signal the carb sees will be poor causing additional fueling issues.

 

[Matt Braley]

Yes the mesh filter has a certain amount of air flow restriction built in to it. The stock jetting is set with that in mind. I think you might be fine at 1 turn out once you try it with the flame arrester on. Maybe crack them open another eighth each while they are easy to reach.

 

[glsmohio]

OK matt I will turn lows out but just to make sure this is how I was testing things. (Just wanted to make sure we're on the same page) I will test asap. Thanks for the help like always!

 

[AdamXP800]

Clogged transfer ports will do this as well. There are three tiny holes in each carb, mark sure they all spray freely when shooting carb cleaner through the jet



96 XP800!
Keep the 2 strokes alive!

Carb port flow tester. I fill it with ATF, it's red so you can see the port flow.

I would install the entire air cleaner with the plastic top and bottom for on the water testing. You need all the restriction from the factory air cleaner for the carb to meter correctly.

thanks for the info. Im going to turn lows out another 1/8 then put it all back together and see what i got

Mine ran its best and highest rpm with factory airbox/arrestor etc. installed after adjustments.

I use my trusty makita compact lithium impact, a flex right angle adapter and hex bit, then I can take the airbox assembly, and arrestor and all screws off quickly while at lake.

what should my top rpms be on a 800 and the 720?

Last season after getting carbs dialed in and fixing water regulator i was at 6940 rpms max on my 96 xp. 100% stock though.

720 not sure, these guys can give you max rpm on that block.
