I have a Craftsman 4-cycle that does a good job.

I have replaced the fuel lines and the primer bulb because they rotted out and started leaking. I learned to not leave the tiller sitting out in the sun all summer.

With my 4-cycle there are instructions in the owners manual to adjust the valves every so many hours of operation. When the valves are out of adjustment and the engine heats up they run poorly.

There are some 4-cycle 2-stroke engines out there that require gas and oil to be mixed. Most of the mini-tillers I looked at before buying the Craftsman were 4-stroke engines with a crank case. The crank case on my Craftsman holds only around 3 oz of oil so I have to check it every time I use it.
