Customer Question

I've installed a 20 resa generator and I'm having a few issues. It has been installed for about a year . It runs well sometimes but then acts like its starving for fuel. LP incoming pressure has been checked and is normal range. Codes are engine speed too high, engine speed to low, and overcrank. Any ideas on what to check. I'm an electrical contractor but not a kohler dealer

Anytime you have an issue like this, the first thing you need to do is to have the internal fuel system tested. A faulty demand regulator can easily cause this to happen.

Without a known good fuel system, anything else you do is moot.
