Is that what Onan stands for?  Went to start the MF1655 today to get ready for tilling. It would start but not stay running so up goes the hood. The air cleaner houseing barely on by one remaining screw. The other two I don't think I want to know. So what does everyone else do to keep these screws in. I thought about locktite but I have to pull the air cleaner too often?

Also, take a piece of aluminum screen wire and form it over the intake. That will keep the engine from digesting the screws!

ever-so-slightly bugger up the threads on the screws.  Then they act like self lockers and won't vibrate out. 

Don't cost a dime - after you replace the missing ones.

Last time one of mine went missing, I found it under one of the valves.  Looked today, another one is missing... good grief.  Really starting to like my new bota.

Tack a small flat washer on edge to each screw head, then safety wire all three together after they are tight. I just thought of this so I think I'll do it to the Onan on my welder.

Thanks for all the good tips, they led me to this. I found and bought some 10-32 x 3/8 fillister screws with drilled heads. I can run a wire through all three screws. Like seen on some injector pumps. That way they won't come out and I won't worry about over tightening them and ruining any threads.

Also the two missing screws were holding the valve open on #1 cylinder. Thankfully there doesn't seem to be any harm, even the screws are not messed up. They will go into the spare parts box.

You're lucky they didn't make it into the combustion chamber.

I use the star type toothed lock washers on mine & haven't had one come loose since doing so.  I like to use blue Loctite also.....with the toothed washers.
