Help!
My '74 TR6 won't start when the engine is hot. It gives me the choice to either
restart it within 5 minutes after shutting it off or to leave it alone for one
hour until the engine has cooled down.
I'm afraid that I have multiple problems at the same time.
When I take off the fuel line to the front carburator (under these hot
conditions) it often happens that fuel will only come after manual pumping with
the lever on the fuel pump.
I revised the fuel pump (1 membrame spring was gone), exchanged fuel lines,
clamps and filter. Is quality of this filter critical? It's a FRAM, >1 inch in
diameter.
This sounds like vapour lock to me but I don't know what else to do.
The carbs have been cleaned and adjusted. The float needle valves seem to shut
off properly.
The heat not only attacks the fuel supply it also impacts the battery. It's a 3
month old 680 cranking amps Delco. Did I buy the wrong brand / type? It's desire
to turn the engine (when hot) varies from just ok to almost none. Who put
designed this thing so close to the engine?
Again after 1-2 hours it starts ok.
Any help is greatly appreciated. A reference to a good mechanic in my area is
also welcome. Two places in this town who claim to work only on british stuff
have not been able to help.
