Hey all!
My 1973 GT550 is done working on fine tuning Jets notice gas boiling/bubbling in the clear fuel lines
From carbs up to tank when it's warmed up is this normal? I have Pingle petcock with 3 separate feeds.
I have UNI foam pods and JL chambers pilots are 35 and mains 117.5 still seams a bit rich but goes like hell!

I've never had clear lines so it's a tough one. The carbs have an air vent on the sides this is to help the atmospheric pressure on the surface of the fuel in the bowl. Try lifting the petrol cap on the tank when it happens as sometimes the air vent in the cap becomes blocked.
