Not sure if this will help much but here is a photo of the underside. The crossmember above the exhaust pipe has what appears to be a shadow of where the spare tire made contact with that crossmember.

Good news. The spare tire is finally back in it's proper position so I'm moving to the next issue which is dieseling.

The idle speed was too high so it was adjusted to a lower speed and when it's in park and the ignition key turned off the engine will diesel a couple of times and a plume of gas vapor comes out of carb intake. If it's left in gear, say reverse, and the ignition key turned off, engine shuts down without dieseling.

The throttle linkage is in good shape with the exception that the idle speed will drop some rpms if the linkage is pressed like the pedal is being pulled up so started looking for the culprit. The AC solenoid is working properly and not touching the throttle linkage when the AC is off so this isn't the culprit.

Looking at the choke linkage and found the vacuum break linkage isn't connected to anything and appears a linkage rod is missing. The carb is a Rochester Dual Jet 210 M2MC and according to an exploded view of it found on carburetorfactory.com, there is a linkage rod number 17 that is missing from the carb. It appears linkage 17 connects to high idle cam 23 and should connect to something else but can't determine what that is unless it connects to the vacuum breaker.

Does anyone have a M2MC that can confirm the presence of a linkage rod connected to the vacuum breaker and high idle cam?

I’m in the process of resurrecting my ‘79 Bonanza Big 10.
Bought it brand new in ‘79, but it sat for 10 years when the cab mounts rusted out.
Keep it, they are a great truck!
