Cu engine blowing back through carb on L/H bank.

Post by fungusface »

Can’t work this one out. Engine has twin Webber carbs. Valve lifters replaced 1k miles ago because of same fault. Head replaced because it dropped a valve seat 500 miles ago. Luckily the seat stayed in one piece so no piston/bore damage. Mixture, timing etc all spot on. Now it’s doing it again. Help please!
