Yes I saw that too. ( I think Vic snuck in the garage late night and sabotage the motor !)  I'm checking thinks out, valve to tight, spring floating, valve seat , head gasket, not sure?  Really, I wanted to give the scrubys' we will be racing a little help and only run the Y Block on 6 cylinders !

I just picked up a new project. Heart Attack 3 ? Not sure about motor combination yet, but could be a Y block for sure . Actually picked up two new projects . A 48 Anglia and a 49 Thames . Larry Short

Why is fuel spraying out of the injectors when you rev the engine? That doesn't seem right

 That is just un-burned nitro shooting out the zoomies

Your right, we leaned it down a little and the problem went away. Larry Short
