Hi Dad_Roman,

I started this thread because of the problems I was having with the GMS adjustments.

I'm glad to say that now, after making sure the case and carburettor is sealed for air leaks, and the fuel intake hole drilled as described, all my engines work great. In fact, I've been able to pick up some at a very reasonable price because other's could not get them to work. The bigesst problem, besides the above mechanical modifications, seem to be the low speed needle being set too lean, or the motors not being fully broken in.

After your post, I looked at the number of people who have looked at this thread, it is hard to believe over 30,000 have looked - I wonder how many we were able to help?

There is no way I could have got the engines running without the help of everyone here. Thanks so much.

Fly4Fun,
