I have added Fenton exhaust with intake manifold heat pipes, I have kept the standard intake manifold and single carb (Zenith).
The Fentons are definately doing something , as now I have the horrible bog off idle. It was running great with the original exhaust manifold.
Is there something tuneable in the Zenith to cure this, or do I need dual carbs also.
