Need your opinions on wheather this engine is worth the effort to use in a rc project?? A 30cc Homelite.

I've had ones worst than that,as long as the cylinder isn't gouged up. I usually clean up the piston and put new rings if needed and also clean any buildup on the cylinder walls.

So I measured the exhaust timing and the intake timing on this engine and I think I did it correctly. If not let me know your thoughts.
exhaust timing: 125
Intake timing : 150
Compared to other posts these seem way off?
