idle speed WD-9

Is there a way to increase the rpm setting on the gas side of a Diesel..thanks in advance..

There is no built in adjustment. You can remove the carburator. You will see a round disc held on by a screw. Take the screw out and put the lock washer under the disc & put it back on. This will give you a speed increase on the gas side

The 650D has a knob in the operator's area that allows for variable speed control on gas. I can't remember exactly but I think it might increase the speed by around 50%. It should retrofit on a WD-9. Don't know when IH began using it.

there is no actual adjusting screws for the rpm. only on the wd40 you could open the butterfly with a screw and get more rpm. on this f8 carb i believe rpm is controlled by the air valve on top of carb.need 1/8" gap between carb body and valve. they only idle at about 400-500 rpm on gas, and as they warm up they will pick up some rpm. what rpm do you have. that is the secret to a long lasting deisel engine , run them slow till oil gets through the brgs. on the JD's there was a decompression lever you pull to register oil pressure then release it and fire it up on deisel.

On my 650D all that knob does is lean it out or make it run rich. The speed gradualy increases as the engine warms up. On my SWD9 that knob does not exist.

manual says to adjust float, have to bend the float tensioner

yes float is adjusted to 9/32 but that is not to do with idle speed.
