First, I'm not going to reply to ANY email account. That's the quickest way to expose my email to SPAM. No - thank - you.

Next, a discussion forum is so that all parties can read, contribute, and correct so that there is value for all here.

Now on to cases. I have converted my John Deere LP tractor to gas, so I can give you the basics. I would think that IH is very similar.

The orifice in the LP carb is not correct for gasoline. You can use the same carb, but the metering jets will surely need to be changed. Or, you can do what I did and find a gasoline carb for it. Just make sure it matches the intake manifold, and that the governor arm connects the same.

Next, remove the regulator for the propane, and there may be a warm-up device which maintains the right temp for the LP and is controlled by the water temp. I had one of these on my JD, and I just took all that stuff off, and recirculated the water hose which went to the warm-up device. Remove the plumbing from the tank, and the tank, then find a gasoline tank at a tractor breakers yard, and install it. Hopefully the mounts for the gasoline tank are still on the tractor and you don't have to make up new mounts. Also chances are good you need a gasoline hood to go with the change, so find that at the breakers yard as well.

Once you get the tank mounted, and the carb on, start the tractor and see if it can be set to idle right. If not, you may need to change the length of the governor rod slightly so that you can set the idle speed.

The timing and advance of LP is slightly different than a gas tractor, and if you want the easy method, just buy a gasoline distributor from the breakers yard as well. Technically, the advance won't likely be much different so it may run ok, but you might not get full power from the engine. Alternately, you could run the engine speed up to full, and set the timing manually and just live with the advance curve or even to get more technical you could go into the dist and change the weights and springs if you can find them on this or another site.

The internals of the engine are the same, but the point gap on the gas engine is larger. Reset the plugs, and that should just about do it.
