Hello there guys and gals of this forum. After a year of "going without forums/social media", I've decided to start back up on here. You guys have all been of tremendous help. So much so that I haven't had much need to post, finding many answers in my forum searches. I appreciate the fast responses and superior knowledge to assist me in learning things with these tractors. So to start, after assistance here, I've discovered that I have a 1959 International Harvester Cub Lo Boy. It came with a 4 foot grader blade and front assembly (Haven't tried the grader option and don't know if I have what it needs anyway) and 70" Woods under belly finishing mower deck (I am painting and rebuilding right now, although in white/red instead of yellow/white). Last summer, I posted regarding issues with my carb and a few other things. She was running fine after said encounter. But there was always a problem after I replaced my 1st battery and removed my carb. I also moved the tractor with the distributor cap off. My governor wouldn't kick in when needed. I tried adjusting as per instructions, but there's about 3/4 inch of play in it. Hesitant to take it down due to my inexperience with these machines, I didn't. But I eventually had to. The governor was surging no matter what position I put it in, and I can't seem to correct the problem. Ignition timing seemed to be ok, but now it needs to be reset. I took the governor off and inspected it. Bearings, weights and all were fantastic. I cleaned all with brake parts cleaner and tried to install the assembly. I did everything the instructions stated for re-install and timing. The fellow that made my gasket didn't get the ID right, so I used form-a-gasket high temp RTV to create a seal. The problem was, Even though I marked the dotted gears with layout fluid, I couldn't quite see where that tooth was going to go. I hope I got it in the right place, as a mirror was useless as well. I gave up for a few minutes and decided to clean up all surfaces a bit more. Unfortunately, my housing fell off my workbench due to my 9 year old niece playing with my vice when I decided to scrape clean the existing gasket. It broke. Long story short, I ordered it and another governor assembly off of Ebay. I just re-installed it tonight, along with some much needed paint to a few pieces. I think even though I may have the gear position correct, I'm still sitting on #2 cylinder under the distributor. When trying to place it TDC, I have some play either or on the crank and can't get it to sit correctly without propping something in the fan blades. I have the two marks, but lack a timing light (UPS was supposed to send me mine a week ago but due to snow and my remote location....). If this thing is off, what can I expect? I have a fair knowledge of engines and definitely am getting a grasp on this one, but could somebody post a link on how to time a governor again? I had the short arm to the throttle control before. This one (thankfully if I read right) has a long arm. It has two throttle linkage holes as well. One or two turns doesn't seem like a difference in the carb linkage considering the play to the spring and bumper in the governor. My question I guess is with this new assembly, where do I go from here? Although I do believe I know where to go, I also know that each type of machine has its temperament and behavior. I figure I'd ask the guys/gals who know what to do. Given enough time and patience, I'm sure I could break this thing down and bring it back up. But I'm still in learning mode. Also, I ordered new AC Delco C86 plugs for it. Does anybody off hand know what the gap setting is for this tractor? Thanks!

.025 spark plug gap.

So you have some sort of governor problem?
I have an excuse. CRS.

Simple things first, the blade does not work well in the grader position of a lowboy due to belly clearance.

As to distributor and governor timing, since you are not using a magneto, the timing marks on the gears are not critical. The simplest thing is to set engine to #1 (fan end) TDC which will be the second mark as it passes the pointer. Note, #4 TDC also lines up on this mark so you need to be sure which one you have. Hand crank makes it simpler than turning fan. Once that is done remove the distributor mount from the engine and turn the rotor under the cap to #1 plug wire, then pull the shaft out of the drive unit and turn it so the lugs line up wit the governor slots and reinstall. When you get your timing light you can make the final adjustment, or if you go to the owners manuals at the top of the age you can static time it.

Regarding the surging, if it still has a problem once the new governor is working some things to check are the rod going to the carb. as to binding and dragging on the corner of the block. Also, the shaft that goes across the front of the engine sometimes becomes worn where it enters the fitting at the governor. Any play in that joint is too much.
If you are not part of the solution,
you are part of the problem!!!

Thanks for the timely response, guys. Eugene, yes, I'm figuring out how to time the governor. I think John has what I was after. I did manage to mesh the marked gear teeth in place. I hope to get this baby up and running full strength before the storm tomorrow so I can plow with the storm (I also sanded and slapped a new coat of paint on the hood as well, due to the maintenance). The "new" governor assembly has zero play and the longer linkage arm, so I think I made out good here as far as parts go. As you stated, any play is too much. I guess my main dilemma was how to position the distributor. And, you also answered my question. I will definitely let you know how it goes. Thanks guys!

I will also add that I usually learn best by doing. I'm terrible at any problem on paper, but I can machine/manufacture you pretty much anything with a blueprint or original piece and fix anything given enough time to understand it. I'm right on that curve where I'm really learning how this machine functions mechanically. It's all thanks to this forum as well. I guess I figured I'd explain why I'm asking what I am. Searching the forums usually gets what I'm after, but some days, I simply need clarification. Many thanks!

Surging: Try slowly pulling out the choke and see if it goes away. If it clears up and runs fine with a little choke applied, you're not getting enough fuel for some reason. Look for air leaks, plugged lines, jets, etc.
