The intake valve is not sealing sometimes. Possibly worn guide.

Pull the head and check the intake is seating and sealing properly. Had one where the valve looked good but gave random backfire in the carb. New valve and a lapping job fixed it.

There are 2 different wheels that look identical but the metal gears are not the same. Seen this problem when cust got new wheels off amazon and the gears barely mesh. Not the correct wheels but "looked" right New OEM wheels and drive gears fixed it.

Probably the best lades are made with marbain steel https://www.fisherbarton.com/products/turf/marbain/

If this is a flywheel magneto engine and not battery try opening and closing by a couple thousandths each side of .020. Kohlers a picky about timing between the magnets/coil and points. Just a couple thousandths will make a difference.

this one is a little higher than than 7.5:1

This tester works good for small engines

In the summer of 1974 i worked at a small airport as a ramp tramp in the maintenance shop. I changed lots of oil in lots of small planes. Most didn't have a filter but rather a fairly coarse screen that might stop fine sand. I asked the head mechanic why no filter. He said dirty oil under...

Just went through something like this on a 731. The original coils on older engines have internal diodes. The aftermarket coils don't have diodes. Not 100% sure but the internet says the new OEM coils don't have diodes. I had a bad coil and couldn't get a new non diode coil to work with the...

Many commercial mowers use a tank pickup like this. Most residential mowers just use a pickup tube with no filter.

I have the Lisle ones and if not careful they will pinch the s__t out of you.

The best thing i have found to cut thhose rock hard tires is an oscillating tool with a hooked carpet blade. I cut the tire rubber off close to the bead then cut the wire bead with a cutoff wheel. But usually i can break stubborn beads with the floor jack and the hitch on my truck.

I change quite a few tires. I have the HF manual tire changer and the mini tire changer. I have a bunch of tire tools, tire soap, bead sealer, bead blaster, plus other stuff. I don't enjoy changing tires but it's not hard with the right tools and you learn a lot of tricks and tips.

Call me a radical but i put a little plain old red grease on the threads of all the blade bolts and nuts.
