I'm starting a new thread on my 1975 MF16 grass cutter.

It's main job will be to cut the grass.

Tractor is pretty much factory stock, no options on it.

Original thread and story of what was done up to this point to make it work as a grass cutter.

:thumbs: Looks like it did a nice job cutting.

Now that you've got that going, what's next?
Still needs some fine tuning, I want to get it working really good so it can be a dependable reliable turn key tractor for cutting the grass.

Tonight I spent a some time trying to fine tune the motor and got it running better.

1 - Governor I wasn't happy with the way it was working, didn't seem to want to hold the engine rpms steady at high speed so I searched the manual and found that I DID NOT have the initial governor adjustment done right, once I set that the way the manual says it works great.

Got the laser tach, set the high + low rpms and the mixtures, tried it a bit and it's much better.

Also I found that the throttle wouldn't hold at high rpm because the cable would slip back, wouldn't stay at high speed so I squeezed the control rivet with large vise-grips and now it holds position.

2 - Fuel pump is n/g, not pumping anything, right now it's gravity feed but I'm going to get a new one for it so when I cut grass going uphill the carb gets fuel for sure.

3 - Charging circuit I put a regulator in it and now the battery charges like it's suppose to.

4 - Starter solenoid is not so good, sometimes it works and some times it doesn't, so I have to get another one.

Gonna take some time but sooner or later I'll get all the bugs out of this thing.

Which manual? Kohler or MF?

Sounds like you're getting it tuned pretty good. :thumbs:

Kohler for the governor setting

MF for the idle speed, they say 2200rpm and at that speed the tractor doesn't shake very much compared to a bit higher or lower.

Sat on this thing tonight again for 2hrs cutting grass, works good, lots of power and runs smooth and steady.

Seems the more I use it the better it gets, working all the bugs out of it.

Today I blew the motor cutting grass. :mad2:

I was cutting long grass for about 45 minutes when it started making funny, unusual noise, then the motor slowed up and you could hear it working really hard, I stopped moving, backed up a bit to take some of the load off the engine from the mower deck but it was still running slow and hitting hard, then a one last funny noise and it slowed to a stop.

I cranked it over, sounds like no compression, I removed the spark plug cranked it over again, the exhaust valve goes up and down but no air comes out the spark plug hole.

I don't think the piston is moving.

So now it QUIETLY sits.

Always something goes bad when things are going good.

So Sorry to hear that Doug, I hope it just lost the rod and didn't damage anything else in the block.

Maybe you better unload the JD216 and just bring me MF16 instead. I'll take a look and see what's wrong with it. I can keep it down here for you where it's warm, it will like that.

That's to bad Doug. You where just telling me last week how much

you enjoyed mowing with the 16. I've got a freshly rebuilt K341 on the shelf, that

you can borrow. You could run up here next week after plow days, drop off whatever

treasure you may have found down south, and pick it up. That way, you could finish off

the mowing season.

That's part of the Hobby, things break.

This time the motor goes to a machine shop, re-bore, turn the crank and fit the piston, rod properly.

I knew the cylinder measured out of spec and the crank was just a hair smaller than spec, but I thought with a new piston, new rod it would tighten it up enough that it would be OK.

Oh well sometime over the winter I'll tend to it.

That's what I plan for the Ford's engine. Should have done that when I put rings in it.
