If it cuts out in prime, then it's not the petcock,
if it is, replace the vac line
When you try it on Prime,... remove the vac line completely, and block the taps at the back of the petcock and on the carb...
Just turning to prime will only work if the vac line is leaking,...
not if the petcock diaphragm is leaking gas...
