nope - just put it on the plastic mounts - I don't remember making offsets -
on my engine - I just push choke closed - turn on ignition flip madly as fast as I can and it starts -I release choke and it is running- takes about 5 seconds (from 50 years of startin old glow two strokes)
-I do NOT recommend this as a sequence for anyone else - It is just the way I do it.
