If I buy one of these, I don't want to have to keep replacing cylinders or having issues tuning. Of course there will be upkeep and maintenance to do. ..but looking for reliability.
I haven't done anything but adjust the valves after 2 gallons of flight time. last year. I'm real happy with mine now. I blew the first one up. Here is the way I did the one I am flying the heck out of now.

And now the instructions are on top of the motor when you open the box. I took it a step further and ran 2 gallons on the bench and now its a screaming machine.
This is after the final brake in period. I had a 24x12 on the motor
