Hi
I recently purchased a Big7 which is not driving at all well. She seems to be sucking air somewhere. She would tick over relatively good but wouldn't take the throttle. When I removed the air filter and fitted a cap over the carburettor she would take it but the power was badly reduced and she sounded like she was off cylinder 3. A lot of work has already been carried out to her namely coil, condenser, plugs and plug leads replaced. The carburettor has been refurbished and reset more than once. The tappets have been reset and a compression test carried out. The manifold has also been taken off and resealed.
Has anyone run across this problem before? if so please help as my 75 year old mechanic is at his wits end.
