Running Rough, Starting & Power Loss
Carb overhauled new gaskets on inlet side new fuel pipes can’t find any air leaks but won’t run even, tried squirting oil around all manifold joints no change in engine speed or running. Can’t think of anything else now.
Would a fuel pump give me these problems.


If it's the SU carb on that car , nothing much goes wrong with them apart from needle , choke tube wear . Have you checked the cylinder compressions . plugs , plug leads , air filter , fuel filter ?

Have you tuned / set up the carb since you got it overhauled ?
