For those who have had questions about the possibility of high altitude adjustment on the Champion generators, I was able to obtain the following information.
When considering tampering with the limiter cap over a screw adjustment: This adjustment affects only the air bypass valve and will not give hardly any noticeable change in the mixture for altitude change. Also making adjustments on the carburetor that are sealed are illegal inside California and should not considered to make a local business play with it and chance a Federal EPA violation and a $10000 fine to go with it. There are after market kits with disclaimers that those with an altitude problem can use provided they do their own installation. Best thing to do is check with the manufacturer for any ideas to assist you of legal adjustments that can be made. Don't expect a magic wand for altitude issues until the manufacturers start using fuel injection and micro computers to meter the exact amounts of fuel and air as the altitude changes. This is coming soon to a manufacture in the US, but expect to pay a premium on any engine using this technology.
