I have an echo 21.2cc engine and I raised the exhaust and intake ports but since I have no experience with this I think I might have ruined the engine . it's 170 degrees exhaust duration and 140 degrees intake duration what do you think?
Spark and compression ok.Plenty of fuel to carby,but I suspect this might be where the problem lies.Tried a mate's carby(working) without any better luck.Frustration setting in....!

Nice bro keep up the nice videos!!

Nice Port! Ur engine los weght.
I have a 26 that won't start.Any suggestions?
Can be many things as always. Check if it has spark and if fuel supply is enough. How is the compression?

@@briangardiner228 Did you port your engine yourself?
No.Don't know for certain if it has ever been ported.Good place to start?
@@briangardiner228 try with a new sparkplug! Spark maybe ok when off the engine but under preasure the plug might be failing.
any big power gains out of this ?
Top end rpms and top speed got better.
Just to much speed.😒
