I had this in the utility section but havent got a response, and realized this might be a better section.
I was working on my friends quad with him, its a 1997(i think) Suzuki lt250 Quad runner.
History:
It was running a while back then just stopped all of a sudden and we never really messed with it at the time. Well, now its good camping weather and we want to go out so we need to get his quad running. Turns out the reason it wouldnt start was because the jets were clogged really bad. We cleaned them up last Tuesday and it started up after a little bit of cranking.
New Problem:
Well we thought we had it fixed. On Tuesday, the day we got it fired back up again, once we had it started it would run good. If you turned it off then started it right up again it would fire up nicely, but if it sat for very long you had to sit and crank for like 5 minutes before it finally would start up. Well later Tuesday night it stopped starting all together. So we spent all Saturday afternoon working on it, cleaning the carb again, spent some time with the air filter, since we beilive that was the source of the dirt in the carb, and some other stuff. Put it back together and nothing, wont start. After some more messing with it I had him take the boot off the air box to the carb and I started playing with the choke(?), it looks nothing like my 400ex choke, and We got it to start up, runs pretty poor, but atleast it started.
Our Ideas:
The carb is different from my 400ex, it has some vacuum tubes that go to the tank to push gas to the carb, and the choke is strange. When you take the top plate off the carb, there is a diaphram in there with the choke peice I am talking about, along with a spring. The needle goes through this choke peice through the main carb tube(venturi?), and this choke peice goes into the tube to. Now when he hits the throttle the choke peice, along with the needle move up, but full throttle wont lift it the whole way up.
The only thing we can think of is that the diaphram has a little hole in it, or something.
Any input on this would be great, we really want to get it going for the next couple of weekends.
Thanks guys.
