Maiden voyage of the Murder Kart! Powered by a Clinton 501 with a generic Amazon-purchased centrifugal 10 tooth clutch, into an 80 tooth alloy sprocket, that is just a tad smaller in diameter than the 10" tires, I was able to get it up to about 20 mph on the street, rip around my yard, spin the tire and completely wipe out my mushroom crop. I will be smiling the rest of the day and I have work to do on it
.
.Lessons learned:
The engine produces plenty of torque to get the cart moving and I will be trying out a couple of smaller drive sprockets in the future.
I left the governor on the engine (auger engine) and it is a bit too basic. I will be adding some springs and doing some tuning to get it to respond better.
I installed an oval Tecumseh air cleaner with a paper element (it's what I had), I believe it is a bit too restrictive for the carb.
The drive wheel was not up to full air pressure so I now have some abnormal wear on the outside of the chain
Although this is not much of a yard-kart, it was great fun in the grass. it picks up anything that is not rooted down and slings it into the foot pan area. also the brake and throttle control linkage points are in perfect positions to pick up all grass clippings
I was able to reach about 20mph (seat of the pants), which is quite impressive for an 8:1 final reduction low drive tire and untuned carb. I assume I can get it much faster with some more work.
Drum brake is adequate to bring the Kart to a stop in all but the most puckering situations as long as it is not having to fight the engine at the same time.
The dash-mounted kill switch works!
all linkages, steering geometry, bearings, seat, etc. functioned as intended.
With only 2" of ground clearance, one must be careful in the route chosen.
Overall a successful first run.

There is a brake drum (slice of 4" pipe) welded to the inside rim of the wheel, to that is welded a 60 tooth steel sprocket. I drilled the 60 tooth to be able to bolt standard split sprockets to the side of it in order to get a better ratio for the small engine.
I started with an 80 tooth (on there now) but the diameter is about 1" smaller than the outer diameter of the tire giving me only about 1/2" clearance between the chain and the ground. Not a problem on pavement as long as I keep the tire fully inflated but it does a number on weeds in the yard
