Re: Hello from 5150 ft elevation
Welcome from 6000 msl. Yep, we have special problems. The most common is getting a carburetor to perform at this altitude but going smaller on the main jet usually takes care of things.
Don't expect neck snapping performance from a 2 stroke, at least until you put few miles on it. But it sounds like you have some experience to draw from so I'm not telling you anything you don't know.
We're glad you've joined us and keep us informed on the progress of your builds.
