Everything is OK with this engine from idle-full throttle.
I must mention though that i have 5-6 tanks of fuel through it right now (12oz).
Am i done with the break-in?
It idles very good.
So,i must also mention that when i am running it rich i see bubbles come out of the backplate.
Is this a problem?
Should i tighten the screws?
Or is the excess amount of fuel that comes off????[]
