Generator wont start
i have an onan 6500 generator. only gets started a few times a year. it cranks fine, but usually wont start unless i push up on the choke lever/governor spring, then it starts up. i ran it today for 30 minutes, shut it off, then tried to remote start it from inside my rv. it cranked, but still wouldnt start properly. its on a 2003 gulfstream sun voyager. changed the oil and filter 2 years ago. unit looks brand new. what else can i try other than having to go outside and open the panel and push on the lever to get it to start?
