Vikki, I would can the jesus clip, the wire clip between the needle seat and the float. I have looked and looked and asked and asked, but I have never found any information about anyone else having problems with the clip. Then again, I was into my carb at least 50 times before I noticed the problem. (The problem was that the clip caused the needle seat to sit caddywampus in the sleeve of the seat, not allowing the needle to seat, and the problem was intermittent. The previous repairs were done by revving the dog crap out of the engine or a couple of wot runs.)

Al, let's do a quick troubleshoot of your carb, and it doesn't cost a dime. (Well, with gas prices, I guess it might cost a dime.) The symptom you describe is a textbook example of a failed accelerator pump.

Before you even get out a wrench, check the accelerator pump's operation. This failure is the biggest failure in quads,a nd it's a normal failure.

With the breather off and pressure on the fuel, meaning just after cranking/running the engine. If it's closed, hold the primary butterfly open. Hit the throttle, and you should see 2 distinct squirts of gas. (Based on feel alone, I can hit the throttle linkage by hand and tell whether or not the fuel acceleartor pump discharges gas.)

If you get just a dibble, broken squirts, or nothing, the accelerator pump is toast. Also, your freind and mechanic didn't offer accurate information. IF you're mechanic says that parts are not avaiblble, s/he may have never worked on a car with a carb. There are many primary jet sizes for the quad, and the secondaires are altered by changine meetering rods and hangers.
