With temperatures turning cooler, I need to address this problem before I find
myself stranded. I have a 72 MGB with SU HIF carburetors. If the temperature
is in the 60's or lower, I can't get it started. It's as if the fuel bowls
are empty. Starter fluid will get it going a little but then it seems to run
out of fuel. I replaced the float bowl valves (jets) recently, so I don't
believe they're getting stuck. Is this just a mater of not having a rich
enough mixture? It seems a little rich as is while I'm driving, and I don't
see how I can pull the choke out any more. Could it come down to the fuel
pump? (Mine's one of those square solid-state deals rather than the original
SU.)
