chainsaw motor vs 5hp honda

[midwestmadness775]

I have an 87cc mcculloch chainsaw engine and in picking up 2 more big mccullochs next week. Im wondering where I could get a clutch to fit on a mcculloch chainsaw engine so I can convert it over to a go kart motor. Or I have s 5hp honda but im wanting to build a go kart that will do atleast 55 miles per hour. If I use this motor and put a straight pipe for the exhaust and rig the governor are there any other things I can do to achieve my goal of 55? I would also be taking the tank and stuff like that off and running. K and n air filter

Welcome to the forum. I do not think that the chainsaw motors are going to give you as much ooomph as the 5HP will. They will also just be more of a hassle to fab up mounts for, get clutch etc.

IMO, use the 5HP and look at THIS sticky

Check out Vintage go kart forum for info on the Mac's. I think you will be surprised on what they can do with those engines.

True enough...however, vintage chainsaws were very much larger than they are now.

The old McCulloch karts were fitted with a 49cc engine & they screamed...

As for a clutch, being a chainsaw engine, it should have a cent clutch fitted...

Old is a relative term I guess. My MCs' were close to 100cc and I have seen some 125's. Personally, I would not waste time on any 2 cycle below 90cc.
An 87cc engine should be ok. Keep in mind that the MC's rpm range is about double that of the Honda.

Do an online search. I am sure there are folks out there than can steer you in the right direction.
