are there any simple things i can do to get some more hp out of my super m. i just rebuilt it with 450 pistons and sleeves, the head was gone through and plained. i thought about electronic ignition but does it really add any power? is there anything i can do with the carb, governor, or timing? i use this tractor for farming so i dont want anything too serious.
 
You can change the carbs venturi or drill out the metering jet, yet the hp that you will gain from this is minor really. Anouther factor that at least i look at if fuel efficiency will go way down if you mess with the carb much. As it is your going to be using more fuel then stock. However if you play with the carb and fine tune the timing you may be able find a few horse. The best thing to do is if you have access to a dyno, get it on it. Then you can really find all the power it has.

yeah i will have to get access to a dyno again sometime and mess with the timing and carb. It cranks out hp in the 52 or 53 hp range so thats not too bad i guess but a few more hp wouldnt hurt anything at all.
 
What job are you trying to get it to do that it won't do now with the improvements you've already made? mike
 
My guess here is that the extra HP is not necessary to do the job, it's just a "would be nice if" thing...

Nothing "simple" is going to add more than a fraction of a HP, and will probably reduce the reliability and durability of the tractor.

For example, the carburetor is designed to give good smooth running from idle to full throttle. If you mess with the carb by drilling or grinding, and you will probably lose one of those qualities.
 
You're on the right track with timing and carburetor settings. Turning up the RPM will get you some more HP as well. Those are the only simple and cheap things I can think of.
