Anyone ever try to use one of these in a minibike ? they seem to 4 or 5 hp these days and all over Craigs list ,, since I dont have one is the crank size right ? Enough Torque to pull around a mini ? Just asking ?
That engine came from the UNIBLOCK family ( itself a decendnetd of another common tech 2 stroke developed by Lauson power products. Thats engine has an intersting history since it almost because an air cooled 3 cylinder marine engine Untill Tech bought them out and ruined the company. The 3 cylinder version was hidden in the old Lauson Engineering building attic for almost 50 years and forgotten untill Tech went tits up and the demo guys found it lucky it was saved ).
There is a high compression head used on the ICE AUGER version.
There is a read plate from the lawnmower version you can add and run 2 carb.
The rod is the weak point in the engine. Too bad no one made a Billet rod and invested somn effort into porting and upgrading these engines. They are dogs compared to a MC but they had some charm and potential not to mention VERY CHEAP...
Older post but had to comment I recently put a tecumseh HSK850 on a pocket bike, and it ROCKS! Goes 40mph and is still pretty quick! Little extra effort in building a engine mount/plate, modifying the carburator to idle/have throttle control, throttle linkage, and exhaust but worth every second spent.
Sounds like a neat set up but you should start a new post on your build and put some picture with it.
FYI,Shoe started this thread and he has past away since this was posted.
