Too bad I missed the buy on an Onan last week, I could've sold it to ya.
I was at the guy's house last night who had it, he had an SS16 that blew the motor, he swapped in a 9 horse Honda motor. I didn't really look over it, but it was a pull start and had it's on gas tank on it. He was running without a hood so not sure how that would've fit even though it looked like tons of room in there.
