From 9 to 5,5 horsepower

My mud mower came stock with a 9 horsepower honda engine. Im having lots of breakdowns with it recently and i want a different engine that runs better and is more reliable. I can get briggs walking mower engines brand new for a very good price and im thinking of using one. But im not sure if their strong enough. I dont need that much power but i dont want my engine to stall when hauling heavy loads. Does anyone have experience with this? Do you think it would have enough power?

What's been happening to the Honda?

there is no spark, my battery is broken and it runs bad. the replacement engine is a pullstart

I think the walk behind engines have the heavy flywheels which would help you take off with a load keep it from dying right there

Push mowers actually have a very light flywheel, they actually rely on the blade to act as a flywheel. Not sure about engine bolting up, but should work fine if the crank is the same size.

figured it would have been the other way around lol

will it work? yes
can i reccomend it? no

Like redline said, they have very light flywheels so that would be a problem. They like to stall very easily. As well as it would be rather underpowered. i dont think it would be very well suited for a mud mower for the sole reason of its not enough power.

as moose said: "I'm sure that it would be better that sitting on the thing making tractor noises"
if the honda is not running and it would be expensive to fix, than go for it.

Tdub ran a 4 hp for a long time on his murray, you should ask him

but what if i would ad a custom flywheel attached to my engine pully would that help? and how much would it have to weigh

I would say try it. It might run fine for you, or you can always add a homemade flywheel to it. No more than a few lbs you should need. Its is 5.5hp I only run a 5hp horizontal Briggs.

u should get a old 10 hp motor small and it wont stall if u have it on full throttle

It would would at least work until you found a bigger engine. I don't know what speed you want to go but if your ratio is right you can get plenty of torque.

Im not lookin for much speed, rather torque. With the honda engine it did about 10mph and since the 5.5 horsepower engine is making about the same amount of revs it should do the same speed. But i already have the honda engine giving spark aigan, but stil wont start. I figured its a carberator issue, so im gonna try to get it running aigan soon
