Can't wait to get some money to get my deere running right with some attachments too.
Do all the b43g onans have that rap noise to them?
Going to adjust the valves and see it it helps any.

Until then here is a video of it running rough.

It does sound a little funny. It does look like its in very good shape though
Adjusting the valves is real easy. Take off the heat shield, air filter, carb and linkage.
Two bolts on each side of the manifold. The breather hose just pulls right off so you can get a socket on the one valve cover instead of an open end. You might want to clean the engine off first, dont want to drop any dirt in there
Setting the timing is easy to. Just pop the intake hose off the flywheel cover and there is a fairly defined line on the flywheel. And the points are adjusted by the wide black box held on with one screw at the pto end on the top.
May want to pop the heads off to and scrape the carbon off.
The gaskets are pretty cheap at onanparts.com or gphope.com

My 318 isn't very quiet not as loud as yours . When your adjusting the valves you might want to look for an exhaust leak or the shrouds around the engine for being loose /cracked.

Sounds like an exhaust leak to me. I would still definitely do the preventative maintenance and get new head gaskets and get the carbon build up taken care of and adjust the valves.

Nice looking outfit!! Hope to see another video after the valve adjustment. Would be a good ideal to check to see if all three screws that mount the breather to the carb are still there. My 317 sucked in one of them, too large to go all the way through the intake valve luckly :yelclap:
