It now starts and runs fine at idle and under heavy load. There is an idle screw and a run screw that is caped so I didn't touch neither. Should I expect this propane to run hotter than gas?

This machine isn't being used much so ......I got time to take it back
in to the shop. And to Terry I understand. I need to get more information.
The exhaust analzyer is what you want to do if you can. Any motorcycle shop with a dyno should have one. A university in your area may have one also. If you have a ATV shop with a dyno that would be best as the mower can go on it directly.

I'm fortunate enough to have a Polaris project manager as a friend (with a ME degree) and another friend doing emissions research (also ME degree) with the tools (even a atv dyno) needed to check it on a weekend or evening.
Looking for blown Kawi 29HP DFI engine's fd791d, whole thing, intake, throttle body, and electronic's. PM me if you have something you would like to sell.
