Close... one of those cheap GX clone 6.5hp or 196cc engines. Generator/tiller/go-kart style. New in the box, but someone dropped it and bent a bunch of exterior parts. So it was cheap... my favorite! 😁

Just getting some measurements to order parts for a build up, later. A little surprised at the nylon camshaft. I will replace it with a Black Mamba Jr. cam.

Looking for about 12-15hp on gasoline... high torque setup for my offroad minibike. I can't do the karts anymore.

I will come back to it, when all the parts are sorted and in hand.

But... yeah... nylon camshaft. 😐

Too clean.... 😆

Just don't want to be accused of being lazy... rainy day.

 

Nylon is widely used in small CC engine because the camshaft profile have very mild ramps . It primarily to reduce the mass of the rotating assembly Those nylon cams will likely out live the engine? In normal use. LOL
You sure are hopeful at an almost 50% power gain? $$$
But don't mind me looks like a fun side project

 

Not as expensive as it was...

I have the non-specifics, check it out.


ARC rod, with bearing insert.

Stainless valves +2mm both, 26# spirngs.

Torque cam

Not roller, but durable. Looking for torque not rpm.

24mm PWK flat slide

14cc head, large valve. This one will be fun, tons of fill and port work possibilities.

 

Switch quit...

 

Didn't I see an Od Rod card with one of your projects... lol

 

Original switch had a plastic clip-in strap broken. It was for a 5 speed. Went to the white automatic car, and pulled the switch.

Let's see what it takes to convert it to a manual... 😁

 

Some of the Mazda B-trucks get nasty in their ignition switches......

 

Little dab of dielectric grease.

Little dab...


Cleaned it with q-tips and acetone. Actually finger nail polish remover... because it is cheaper by the OZ.

 

The best part... the wife doesn't complain about the odor. Smells like nail time! 😆

 

I can’t get my Xylene anymore and have to go to RENO Nevada cuz our dictator for a governor billed it as a pollution chemical .
