Wish I knew more to help ya out... Check out PWCtoday.com....If you haven't already...seems like I get answers quicker there than I do here but both sites are good in their own way...good luck!

hah thanks:biggthumpup:

Cool, thanks

I found a finger throttle for my 650sx that's coming off of a 750sxi. Just wanted to see if it's gonna be a clean swap or if I need some kind of adaptor...Thanks guys

Shop manual says 1 turn on low 5/8 turn on high for the stock 28mm carb.

Well...just got back from taking it out...a little too early for my taste. Taking the carb apart and cleaning it did produce some results but not as much as I would have liked. The only way the ski would start is with choke. I ran it a good two minutes just above idle to get everything warmed...

After taking the carb apart, cleaning it and putting it back together I got my ski to start and idle on it's own. Sounded kind of rough at first, but I went out to start it right now and it sounds strong and as good as it ever did. Going to take it out tomorrow and see what it can do. I am...

Lol yea....just seems like it ran smoother before I started having issues...:silly:

Cool, I'll mess with it some more tomorrow...then take it to the water and see what it does. Gracias Senor.

Took the carb apart...and sprayed carb cleaner all over the place. Put it all back together and twisted screws to about where they were when I removed them... Put the ski back together and it started right up let it run for 10seconds or so...givin' it a little throttle and it doesn't seem to...

I have my 2 skis sitting on my trailer. The exhaust from the one I am messing with is aimed right at the other ski. I just looked over there and there is black grease everywhere...am I doing something wrong? Gonna get some pictures of what I am dealing with for ya....

Bypassed the fuel selector switch as recommended, starts and even idles but as before it sounds really rough. Also after I kill the engine, I can see what seems to be A LOT of fuel dripping down the carb. I want to take the carb apart and clean it up. I am also considering getting new fuel...

Oh heh, forgot to mention...fuel and oil tanks are to the top. Gonna go try bypassing switch right now. :biggthumpup:

I swapped out the carb from my top-end needing 650 to the one I have been having trouble starting and with the other carb it'll start but won't idle and run rough. Instead of wasting the time and money on the stock 28 I was hoping to upgrade to a 38mm Keihin. If I tear down the 28, I should...

Unhooked the carb from fuel pump and it does spit out gas. Unscrewed the low needle and it looks clean. Pulse line looks like it is in good shape. What else could it be? I have been messing around with this thing all afternoon. I reconnected the battery and it started on the first try then...

Alright I tried trouble-shooting like some of you mentioned. WD-40 in Filter bowl didn't seem to do anything. I tried covering the Carb with the flame arrestor still on as best as I could and still didn't start up. I will check the low jet tomorrow and blast some cleaner in there. Gonna...

Went to Lake Havasu this weekend and had to ride my friends skis because my don't work. That's why late response. I have been considering a new top-end for my other 650 that absolutely needs it but from what I have learned is that I am looking at about $300 for parts + boring and that's not...

Yea...stocker 650sx with separate fuel pump. Where is the "filter bowl"? Gonna go try covering the carb, by hand, right now. See what happens... If it happens to be that the carb is the culprit, I don't want to waste the money on rebuilding the 28mm. In the process of upgrading to...

No Primer...took the FA off and blasted some carb cleaner in there...While hitting start and blasting the cleaner in there, the engine will start and run off the cleaner. When I stop spraying, it runs while it burns whatever was left in there but dies soon after. My guess is carb or fuel pump...

will pull and check
