<DIV><FONT face=Arial size=2>air leak somewhere! gaskets....valve cover,
carb, reg gasket...throttle barrel seal...head gasket....something is leaking
air. Sometimes its a small leak and doesn't affect performance much.....but look
for leaking fuel in the engine compartment....A new set of gaskets would go a
long way...could also be a o-ring...like on the pushrod tubes, maybe a intake
tube O-ring....Usually these things are easy fixes.....but its leaking somewhere
if that reg is not sealing.</FONT></DIV>

Fuel system has no leaks. However, when I defuel, the pump sucks air
bubbles in the fuel. If I pinch the fuel line at the regulator, the pump
primes and no more bubbles. Regulator has a new diaphragm in it.
Engine doesn’t appear to leak fuel anywhere when running. Something to
worry about? What should I check? Thanks in advance!
