Default RE: 3W 55i problems

ok the carb is drawing fuel to prime now, but you're still dripping fuel out of the needles. And when the engine starts, it just burns the prime and quits.........Correct?
Correct

Running on prime and quitting means lose of vacuum to operate the carb diaphragm..... or plugged carb........but the carb will draw fuel to prime....(real head scratcher) If the reeds have just been replaced, that shouldn't be it.
That could be a bad ignition/battery/switch also but all of that has been replaced with the exception of the ignition module itself

Needles dripping fuel.........I've never seen this on any 2 stroke I've ever owned. My one chainsaw with the o-rings on the needles had a bad o-ring once and would lean out and die. Drove me crazy finding it.
Don't get me wrong, it may drp one drop every minute or two. I just checked the needles to wobble like 1mm. I also looked at the needles themselves and noticed they are different sizes. The high speed needle has a nice long point on it and the low speed needle has a short stubby point on it. I'm wondering if they are in backwards. I never removed them that I can actually remember


Any chance you got an extra carb laying around you could try?

Were's Ralph when you need him.
I wish I had another carb to use, that would answer this once and for all and I agree I would love to see Ralph pop in here.

I just got an email from AI and they want it back. They gave me the exact procedure they used to test it and according to the email it gave them no problems. The real problem is they close on Friday until Jan 2 2007 so I'll have to wait until then to send it back, but if I can find the solution before hand then I would be happy with that. I don;t mind doing the work it's just that I'm out of idea's

Let me reiterate, Gerhard is trying his best to work with me on this, I've been pretty busy these last few days and did not realize they were open until 10pm. What's nice is they are around 100 miles from me so any shipping via ground is usually there/here overnight
