Thanks for the confirmation, jmech. I didn’t think it did. Seems it would be fighting the governor(?). Maybe it’s actually part of the problem I’ve been seeing.

Clearly somebody has done some shade tree mods to this thing to in the past. Taking advice here, I’m trying to get it back to the way it was designed and will go from there. Once I get it running right, this engine will likely get swapped into a 126 roller I’ve got in the corner and I’ll rebuild that engine completely..

Thanks, again for the help. I’ll jeep reporting back.

Download or get a copy of the Kohler engine manual. It's on this site here:
https://www.onlycubcadets.net/forum/...ead.php?t=4646

Find the section on the governor and readjust it. Make sure the governor spring is in the right hole on the governor arm. Those holes adjust the sensitivity. (The holes in the opposing arm are for setting the dash throttle lever travel.) Then return the carb and set the low idle. Get a tach and set the high idle-no load. See what you get after that. Yes, that spring would fight the governor spring.

OK. Think the extra spring must have been to keep it from hunting. So clearly somebody decided to fix a symptom instead of fixing the problem. It’s not bad at all. I’m suspicious that it’s got an incorrect governor spring, but didn’t have time to dig anymore last night. May be as simple as adjusting the spring or installing the correct one if it’s wrong. Either way, it should be an imminently fixable problem.

The quest continues this evening and between rebuilding rests on a P218 for my John Deere.

Thanks, again for all the help. Will keep reporting as work progresses.

That’s cool if they’re not too expensive. Just using a square piece of stainless right now. Can you post a pic?

Thanks.

OK. Update time. Got the sediment bowl and gravity feed fuel flow(instead of pump) going. No real change.

Moved governor spring to correct ‘starting holes’. Seemed to be much more consistent, less ‘hunting’ in first gear. Set idle and throttle screw to recommended start point per manual. Thought problem was solved.

Mowed 45 minutes without incident in first gear(pretty slow, but trying to establish a baseline). Dropped to neutral and ran inside for some water, 3-4 minutes, when I put it in gear and let off the clutch, it died. Played heck starting it back up. When it finally did start, it was backfiring - a little at first, then almost constant. Seems I need to check the timing, but why all of a sudden like that?

Try tuning the carb. The carb settings you used are just preliminary, or like you said "starting position". The purpose of that setting is literally so it will start and run so you can tune it. Not run it for an hour then tune it.

Adjusted the carb with little or no change.

Timing was out of whack. Tried timing it with the static timing procedure her posted by jmech. Apparently I’m not smart enough to do it that way. So I set the gap to .022 and it seems to be running OK - at least it isn’t backfiring anymore. Didn’t get the chance to take it for a spin. Had to get the grill going.

Why’d they put that dumb flywheel window on the opposite side from the points?

Seems we’ve got it running good. Bush hogged a good acre or so yesterday with no issues. Thanks for all the help.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
