Default Onan 15.0 Built sheet off serial #

I was hoping someone could post a build sheet for this 12 wire 15.0RJC. I can not find the data tag anywhere on it. Any ideas where to look for the ID tag on a RJC?? Block # 306710

$160.00 and $30.00 in gas, I can turn the flywheel. The seller said the dist. quit turning, he said the gear that drives the dist. is not turning. It's been sitting for about 6 years he said.
I couldn't pass it up, Tri-fuel carb., newer starter, demand regulator with shut off solenoid. A beautifull drive pretty much all in the mountains it was!!

Thanks!

A few more pictures.

The guy also has a Kohler and an Onan 12 RS both in need of repair. The RS he said started making a knocking noise.

The tag on one like that are usually on The control box.. could possibly be inside?

Good deal! Hopefully the gear drive for the distributor is not ground up..

Joe,

Have you ever seen a bad camshaft on a JC?

Is Florida agreeing with you?

Yea, "Nice Score".

I have not found a data tag "inside" the control box yet, usually they are inside door on a housed set, but outside on the rest.

I have not seen a muffler set up like that until now, interesting set up.

The build sheet says spec. AC, but I think this is the right one.

Yes, B150 option is listed.

Thanks Max and OnanParts!!

The B150 makes sence, I measured stack lenght on a 3 phase 15.0 JC and it was 5 1/4", the stack length on this 15.0 RJC measures 16" so a B150 full output it is.

I also pulled the dist. today after getting it unloaded and i it's resting place for now, turning the flywheel I can see the crank turning but, the camshaft is not si sometime next year when I get room made in the garage, I will tear the engine down to see what the failure is.

Did you hear any grinding noise or feel hesitation while turning it? With the plugs out

Joe, I only turned it a few teeth on the flywheel and felt the cam not move then stopped.
Why do you ask???
I did notice the governor was not holding the throttle full open, maybe something in the front gear cover came apart. It will be very interesting to see what happened. The guy did say a place in Colorado Springs had rebuilt the engine and he only got about 50 hours out of it before this happened. I never thought to ask hime if he ever tried to get warranty out of it. Since it's been sitting like 6 years it really doesn't matter.
