my mf50 takes a good 15 mins on 10 degree morns to run good. it starts right up but putts and misses till it warms up and then runs like a champ. is there something i can do like warming the intake? or anything to shorten this long warmup or should i just stop complaining and be happy...
seems like when i first start it if i bring the rpms up slowley to 1500 hundred it smooths out alittle faster. like i said once warm she runs fantastic?

Not familiar with the 50 but
Thermostat OK? Has to be first port of call.
Cover the radiator partially but with a care that you do provide enough cooling area when it"s working hard.
Working the tractor reasonably hard(but not silly)initially will speed up warm up of course.

Mike,
I have a similar problem with my 1957 to - 35 gas.
I do believe we are better off that after a short warmup period the tractors run smooth. Rather have our problem than one that will not run and pull strong while at work.

We must remember these tractor fuel systems are near 56 years old.

All I can tell you is insure you have the electrical system in excellant condition. Run non-ethonal fuel, install a in - line fuel filter.

Tune the tractor so it will idle at 400 rpm, if the motor will not idle at 400 rpm 's you do not have it properly adjusted.

When you have it properly tuned, put the disk on and take it out to some open area (engine warm) . When you put the load on the tractor and open the throttle the engine should take the fuel with no he -cups.

Good luck

yea once warmed it will idle at 400rpm no problem. i did go threw all throttle adjustments pretty extensively. have the carb adjusted also. and everythign on the tractor is new, all ignition parts, tune up etc. i have heard of putting a heat gun and warming the intake or even putting a light bulb on the intake. im really thinking its just ice cold air being delivered to the engine before it warms? it was 5degrees the last couple mornings.

You might want to check the intake manifold gasket. A small leak due to corrosion can turn starting into a problem in the cold weather. Then, when the engine warms up, the manifold is pulled tighter by the expansion due to heating and all is well. Take a propane torch --- don't light it-- and if you get the engine to start turn it on slightly and hold the end to the seam of the gasket slowly working your way around as much of it as you can get close to. If there is a leak you'll get a definite response and you'll know that you need to replace the gasket after trueing the face of the manifold.

aahh a cold start intake leak that seals when warmed up, very good im going to look into that because my manifold is worn and looks like the original..

The 2 piece wooden clothes pins. After a full choke to start, keep both clipped on, then leave one on the choke rod till it is warmed up.
I clip them to the tin under the dash till next time, but if you have a toolbox with a bottom, that'll do. Low tech, but works for me...

Uh, they're not fuel injected or computer controlled, they do need to warm up a bit before use. How soon we forget..... Laughing
15 minutes sounds about right. I fire the 202 up then go find something else to do for 10-15 minutes before I even think of doing any work with it. Summer time is a different story all together.
