Hello all,
My bike is spitting back badly through the carb. The carb is the correct Amal 376 (which looks fairly new) and is jetted correctly. She’s awkward to start from cold now and I’m having a bit of trouble getting a steady idle.
I know she’s weak and is drawing air in through through the inlet manifold/head joint as she’s failing the carb cleaner sprayed on the joint test whilst running.
I’ve fitted new gaskets from our hosts all round but still no good.
All mating surfaces are clean and true with the exception of the head flanges. When a small straight edge is placed across them they are “high” in the centre area and the straight edge rocks. The manifold edge is perfectly flat.
I’m loathe to tighten down too hard or pile on loads of goo.
Your thoughts as always would be appreciated,
Cheers.........Shaun.
