1541 Throttle Cable Adjust

[gkingbing]

Hi Folks,

Is there a process anywhere on how to adjust the throttle cable. I can get more RPM's out of the engine by manually increasing it on the carb but not sure how the governor is set up. The throttle lever will not go to the top of the limit on the dash. Would like a little more pushing power when the snow comes. Thanks

How fast is the engine running?
Just because the throttle lever doesn't go all the way up doesn’t mean it isn't running like it should.

Get you a hand held tach. Check if the engine is putting out 3600 RPM at full throttle. Almost all small engines can do well over that but once you pass the 3600 speed you start loosing power and creating major wear that will cause the engine to fail prematurely.

Or you can do like I am and put a digital tachometer on your tractor. That way you know what it's doing all the time. And 20 bucks is much cheaper than a new engine.

I don't know how many RPM's you think is "well over" 3600..... but the flywheel's integrity is limited to 4000 RPM. I don't like to go above 3800 for risk of exploding the flywheel. So.... safe bet is 3800.

I have a Case 444 that has hit around 4500 or so momentarily while adjusting the throttle stop to max out at 3600 which Kohler says is the max RPM for the engine. That's well over what Kohler says.

Momentarily is not the same as continuous. I think you are totally missing the important point......

I have no idea what you were doing to your Case... and it doesn't matter. Anything over 4000 is not necessarily safe. That's why there are 4000 RPM rules in pulling. Anything over that, a steel flywheel is required. No, it won't explode at 4000. May not explode until 4500, or 5000..... but it has been proven that 4000 and below is safe.

Thanks much for the feedback. Everything I have learned about the 1541 came from this forum. I like the digital tach idea and will try to find one. What would the wires be connected too? Thanks.

The tach is just a hand held tool that reads a piece of reflective tape you place on a rotating part.
