Yep. I just wasn't sure where flywheel clutch compartment was. Now I do, thanks to everyone. Book is good but being so new, a little clarification has been great.

My guess it is the governor. You can bypass it with a thin rope or wire connect to the governor lever. When the engine bogs down, pull back on the rope thus bypassing the weights. You can inspect the governor parts by removing the engine breather and looking at the weights with a flashlight. The governor has an adjustable link on the outside. Bill

If Bill's idea does not solve the problem, farmerize it with tank up higher than the carb when the nose is headed up hill. If that proves to be the problem then time to fix the mechanical pump or add a electric fuel pump.so the hydraulic pump doesn't need to be moved.

Thanks for additional comments. I was curious that gas just gravity fed but I figure it's been that way for years. I think machine was working fine when parked so I'm hoping that tracks and clutch will solve issue. On my cars, i always try and play the game of " what changed.... why was it working yesterday and not today". So im trying to figure out what changed with machine sitting for 20 years and address those issues first. If not, I will try these other things as well.

If you don’t suspect a fuel supply problem I would suggest that the tight tracks might be your power problem. Tracks to tight will rob a lot of power from a small tractor. Nice looking tractor, Mike

Hi do you have any stiff track links? If so then that makes the total track length shorter, like an over tight track, harder to roll.

Does your 22 only bog down on hills or does it tend to stall if you push a pile of dirt? My 22 would run smooth as a clock but would stall if put under almost any load at all. I suspected the governor and was not looking forward to taking it apart. Someone on this forum suggested opening the main jet needle, and that solved the problem. I have used it for pulling stumps since then. I am curious about your hydraulic pump and why it is in the way of the fuel pump. A photo would be nice. Best of luck with it. Grant.

More good info. It's been spitting rain and snow, so I haven't looked at 22 since all the comments. I think it's a combo of tight tracks and clutches out of adjust. The carb was just professionally rebuilt and it runs great. I haven't had time to push any dirt with it yet, so I will be curious if it bogs down then as well. Another detail I forgot... it was bogging down going up hill but the instant I put clutch it, rpms would come right back up. So on a few longer hills, I would clutch in to let rpms increase a few times on my way up. I'll update this next week when I get a chance to spend some time on it

Hi, tkgeorge99.
Were you running the 22 on gas or had you warmed it up and switched over to kerosene? Thye usually did better on Kero.

The tight and stiff tracks could be much of the reason why it lugged down on the hills. Ideally, it should have about 2' of sag between the front idler and the rear sprocket. Having them guitar string tight places extra load on the final drives and the associated bearings - a recipe for disaster.

I would recommend loosening the tracks off - a pretty major operation on those old girls with FOUR adjusting bolts to get freed up and adjusted evenly - and I would make sure that there is plenty of anti-sieze/kopperkote where the adjusing bolts pass through the threaded lugs. If you can arrange to sit it in a fresh water puddle for a while - maybe several days, you will likely find that the section of track that was in the water will have loosened up. "Wash, rinse and repeat" until the whole track chain is free on both sides.

These little jiggers were about as bulletproof as a small crawler could be back in their day. There were around 15,000 of them sold in the 2 series, 2F and 1J.

Just my 0.02.

Just following up on previous posts...
The 22 is running fine and most of previous issues have been fixed. So I did a complete change of engine oil, gear oil, and all the lubrication recommend. I loosened up the tracks to the proper tension. Cleaned main clutch and track clutches as well.
So now it runs and drives pretty well. The power lose seems to be better. It still bogs down while pushing a full dozer blade of dirt but I think that's normal. Not super speedy up hills, I think also normal. It's no D6 but it does ok for only having 20+ hp. But very functional.
I ran it for about 4 hours and it did great. I have my boys, age 17, 15, and 13 all driving it. They love it. One drives and the other works the blade. They are getting pretty good at pushing dirt around.
It's been a super great project for us and I just love pushing dirt around with it. Thanks for help and advice
