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...

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.

"The rod and crank journal cleaned up good with some Scotchbrite." Did you install a new connecting rod?

Run it till it dies. Check for spark. If it has spark remove the air cleaner and spray a small amount of starting fluid into carb. Does engine start and run for a few seconds. If yes it has a fuel problem. If no then compression problem and need to remove carb and tank and check valve clearance...
