Engine break-in complete, one issue...

[Longhorn Man]

a rich idle mixture will not cause dieseling, a lean mixture will.
Lean causes more heat, and heat causes hot spot, and that ignites the mixture without the spark plugs igniting.

Odds are the dieseling effect is due to the timing and overfueling of the engine. I agree that lean will make it run hotter, but a new engine would not have carbon to get hot and cause the problem to much

OK. First you need to set that timing. Letting that engine run is not going to hurt it. We are not talking hours on end here, more like 15 min. tops to get the timing set. Currently, when you restart the engine after it has run, dose it crank hard? Or dose it spin easily? Timing being too far advanced will cause it to crank hard. As for what to tell you to set the timing at, every one of us will tell you something different. Every engine is different. Sort of like a personality. You simply need to find a number that the engine is happy with. After you get this done, I am sure you will like that engine a whole lot more.

Good Luck!

No, seems to start fine... No issues...

Once i get the cab on, im going to replace the filter, add another quart of oil, and then do another 20 mins and adjust the timing... Idling at 800 rpms is where we should be right???
