H wont come up to full RPM.

Anonymous-0 · Jun 13, 2010

I have a 44 H, it is an ok tractor. I have to pull it to start it. Working on that at the moment but another problem i have is that it never comes up to full power. The governor does kick in, well sometimes. But it was especially noticable when i was pulling a brush hog and barely could cut the grass. I don't know where to start with it. Any Help would be great. Thanks =Keith

since it starts hard you might want to look into the valves... as for the reving up you should look at the rods and make sure they are adjusted so it can rev up enough..

Please clarify exactly to which "rods" do you refer?
Carburetor rods? Please be specific so I can be enlightened! Thanks.

Try opening the main jet scr?w near the bottom of the carburetor as this will enrich the fuel mixture. Even my garden tractor has this feature
as many old lawn mowers. Hal

The spring inside the governor is weak, or more likely, the holes that the spring hooks into are worn out and you"re getting a delayed response when the governor tries to compensate for a load. There are probably some other parts inside the governor that need some attention also.

The first thing to check on these old gals is the ignition timing.

As the points wear, they will in turn directly "slow timing", which really drags 'em down.

On a '44, I imagine you have a mag, and therefore set to .013". If your tractor is equipped with a distributor, set the points .018-.020".

Then, feel out and set that timing to where the engine breaths free. Oh, and carb adjustments should always be done as the last step.

This should make for far better starting also.

Leave that point gap at .013 where the factory put it. Increasing it will only cause your coil to burn up faster. If you want a hotter spark, buy a hotter coil, and/or convert it to 12 volts.

Check your high idle screw inside the gov. It has probably vibrated loose and moved on you. Set low idle first, then high idle. Check your serial number tag for the high idle setting. While you're in there, spray everything inside the gov with carb cleaner and make sure it all moves like it is supposed to, and don't forget to check for broken parts, like the spring, which may need replacing anyway. Then change your oil and filter. If this doesn't do it, the gov may not be adjusted to the carb correctly. If you need to know how to do this, let me know.

There are no rods to adjust on the governor linkage. The throttle lever does have link rods, and these do need to move the governor control lever (back of governor) through its full travel from idle to full power. If it runs OK the valves are not the first problem. A valve adjustment is important, but it is after ignition timing, and fuel delivery issues are solved. Jim

If you could tell me what the correct settings are on the governor and the carb are that would really help. And what all is involved with the governor. I have yet to work on this part of mine
