Hi there,

Do you have a timing light?

What distributor, what carburettor, and what's done to the engine?

Hi again,

Has the engine ever run in this setup?

Sounds like your ignition timing is wrong.

Do you have a timing light?

Has the distributor been fitted at a static timing figure of say 15 BTDC?

I would open the spark plug gaps up to .035.
