Can anyone tell me on a 190XT gas 301 how to time the oil pump to the camshaft so the distributor drive will be correct? I can not find mention of it in my engine manual.

Using the crankshaft pulley, rotate the engine to TDC on number 1 cylinder. Install the oil pump such that when things are correct, the rotor in the distributor is pointing directly at the number 1 spark plug wire lug inside the dist cap. Using a timing light set the timing at 25 degrees BTDC at full throttle.

I noticed in the manual it shows 26 degree BTDC for diesel. The the gas and lp just show 26 degree. Are they both the same and they neglected to show the BTCD on the gas and lp? 26/25 not questioning that.

Thanks. I just looked at crank pulley. Marks don’t go that high on after side.

Also use one heat range colder spark plugs like AC Delco R44XL or XLS. Those engines cannot be allowed to detonate one bit. The tops of the pistons break off leaving the skirt and pin going up/down inside the cylinder sleeve.

Got it running. Haven’t set timing with light yet but will today. Only issue now is every time I move the throttle the governor starts surging until I grab the linkage to stop it. It doesn’t have a secondary spring that has been added to two of my others but never has had one. I’ll go through manual and look about linkage adjustment. Just not sure what I did that would have changed it.

Provided there is nothing catching/binding on the governor to carb linkage, lengthen the yoke on the link rod a couple of turns and see what that does. No surge spring needed on that engine.

There is no adjustable main jet. It is fixed like a Holley carb on a car.

I’m totally confused now. When using timing light the timing mark lines up with the right side pointer to run decent. This is a combine engine and the combine front plate does have the pointer on the right. The tractor plate has it on left. I used the tractor crank pulley but left the combine cam in it, which is different than tractor cam, mostly just because I thought it would be better for wear with the rest of the engine even though it is a lower rated rpm. Is the cam making it time to the right side pointer. Crank pulley is keyed so it can’t be wrong. Timing marks on the gears were lined up. The only other possibility I can come up with is I did use a salvage yard crank pulley as I broke my original during removal. I think the salvage pulley was marked 180 or 185. They looked the same but I never checked the timing marks location to see if they were same.

You've apparently got a diesel crank pulley. Just set the timing to 25 degrees BTDC (at FULL throttle)  from the right side and forget about it.

That’s all I could really figure. Not enough experience around diesels to know they were different. Mystery solved. Thank you very much.
Any idea why the offense in camshafts. Part numbers showed combine 301-G2800 and 180-G2500. Rated at 2000rpm. Showed 190XT-G2800 and 190-G2500 using a different one rated at 2200rpm. As mentioned above I stuck with the combine cam as most likely it will only be used light duty from here on out and was advised I would probably not notice the difference.

Pretty sure the "grind" profile of those camshafts are all the same Older camshafts had a press on drive gear. Later models had a long bolt retaining the drive gear. Hence, two different p/n's.
