I picked up a MF 12G while in Portland Or last weekend, was looking for a lawn mower to mow the lots next to my landladys house. paid 75.00 and drove it onto the pickup.

1. the key will not start it. have to jump across on the terminals.
2. when engaging the mow deck it has to be done slowly, tho dose seem better after greasing the bearing casings. it dose spin up better. but needs to be slow or the engine dies.

3. when the engine starts to die, depressing the clutch, and retarding the throttle will keep it running.

4. wont mow much or far with out the motor dieing.

I am new to this area, was glad to see that they are collectable and have a following. I had bought it because it was a good price and well built,, plan on using it in the garden also. can anyone help, guide me to resolve these issues. I do plan on tearing down and rebuilding/restore this winter

:wave: Justpics Welcome to GTTalk! I don't know much about the 12G Masseys, but there are a lot of folks on here who do and I'm sure that they'll be along shortly. From what I understand, the 12 G's are a superb machine, built to last with plenty of power and available attachments. I think you made a great deal for $75! Hope that you get it going soon!

Sounds like money well spent, and I would look into cleaning the carb if it has sat for any length of time. And my recommendation to clean the carb of a running engine like yours is go to Walmart and buy "Gumout - Entire Fuel System Cleaner" and dump a little in the gas tank, it does wonders. I usually just let the tractor sit and idle for the first 15-20 minutes after dumping the Gumout in for the first time. If that doesn't fix it there are more solutions, just tougher.

:welcome: to GTTalk!

Yes, you got a good deal. Maybe better than good.
I do believe there are going to several minor maint. adjustments and possibly a carb rebuild in your future... but Casey has the best first step. Try some carb cleaners and also look around here a little bit to read up on the effects of ethanol in the new gas and also the benifits of SeaFoam for continued long term reduced troubles.

When you get the chance, there is a service manual that will be invaluable. It can be found in the manuals section under Massey Ferguson. Good luck with your new GT, and if you have pics, please post them.

Justpics, welcome to the best forum going. I agree with all that has been said and hope your new tractor gives you many hours of service. There are lots of folks with knowledge of your 12G.

Thanks for the welcome, and for the advice, I enjoy working on things so this will be fun. the local MF dealer was very helpful printed about 50 pages of part diagrams for free. was told to check the compression as if it is low that could be one of the problems. looks like the ignition switch is shot, so will replace that tomorrow.

pictures will be coming.

Sounds great, good luck with it. I had a shot ignition switch on one of my tractors, still rewiring the whole tractor but that's a scope creep problem lol.

Make sure you get the right Ign switch for it. You need a mag style, not powered. If you put the wrong one on, you could kill a very expensive part on the ignition system. May want to go back to the nice dealer for that one, unless someone here knows of a generic drop in?
:anyone:

Keep in mind that if you take a compression test using the plug hole the engine has a decompression valve that doesn't kick out until about 2000 rpm, so it will not show true compression when cranking the engine. May only show between 50 and 60 psi.
