MF 65 CARB

This engine is 50 years old and many 1000 hours of operation. Trying to increase power and performance shd have a sad ending. I have few old MF,s like yours which I take great care. If you use good quality fuel and oil for engine and rear train...if you keep all filters clean and changed regulary....good anti-freeze....good battery and working charging system....good tune-up and (no customize....ha ha!) you will obtain great power and performance.

You may spread expenses year along this month engine oil and filter...next month change anti-freeze next month change rear end oil and....

All this said it is "your tractor"

Good luck !

On a low rpm engine, power gains come from more efficient combustion instead of flow. Good mix and swirl are mandatory. The next bump would come from a compression increase. The stock replacement pistons for the 65 will net a 9.1:1 compression ratio over the stock 7.1:1. Ignition timing and valve clearances could be fine tuned.

I do not think the carb on this engine limits airflow. I have been toying with the idea of fuel injection... I could adapt an early GM setup... Or I could just finish my resto!

The answer is yes and yes. I was going to go through everything, and found everything shot in the process. I am currently hemmoraging cash at a rate that is alarming the spouse. My body man picked the paint, so I am not sure what he used on the tin. Looks great, though. I will be using Omni (from PPG) on the chassis as it is $67 a gallon while the PPG is $193. I plan to lay several coats, so it should not be a problem. The primer is Omni high build over Rustoleum Red Oxide Epoxy Heavy Rust. I am using it due to the fact that it seems to adhere well and shows what has been primered. With grey primer, I have difficulty discerning what has been painted and what is bare metal. It looks great till three days later and it begins to surface rust. I am several months away from any real painting, but that is the next big project after I get the front support bolted back on. It is currently at the machine shop getting the pivot rebuilt. More cash....
