Default RE: GMS Engine Tuning Problem

Hi Andy,

Your probably right, drilling the nipples may not have been necessary.

I had actually done all three things at once, that is, drill the 2 nipples and the inlet hole at the same time, I had a free day that I wasn't flying, and probably did more than I should. I'm really not sure if all three procedures are necessary or if one would have done the trick. It would be interesting to know.

If you had the time, you may want to try one at a time and really isolate the problem.

Also, I was thinking (I know, its dangerous) if the problem was the carb inlet hole and the inlet nipple hole not lining up, and thus restricking the fuel intake when the nipple was tightened down (by partially blocking the hole). Then perhaps just putting an extra spacer under the nipple flange might hold the bottom of the nipple far enough away from the inlet hole to stop it from partially blocking the inlet hole - this may do the trick and allow the fuel to flow freely.

Its just a thought, its too late for me to try since I've already drilled the hole.

Let me know how you make out with yours, I'm really curious.

Thanks for your help.

Fly4Fun,

Wayne
