[FlatheadTed]

Advance is up for both the crab type?and the helmet.We were flicking the points on a Model A the other day it had a new condenser on it .we were getting a few shocks (made me jump a bit ) and reasonable spark of the HT coil wire .after adding a second original Flathead condenser at the coil it started jumping almost 1/2 "
The symptoms you describe can be any number of things they can all give smilier problems .a voltage drop due to dirty Ing switch or bad low tension connections .a badly earthed condenser .leaky vacuum .secondary jets blocked ,bad coil .week points springs ,condenser ,faulty fuel pump .
