THANKS for all your suggestions---it appears to be rust/garbage in the fuel
tank & lines. Runs great in the garage but as I get it out on the street & up
to speed it starves for fuel.
Thanks again!!

Subject: TR3A Runs great til it gets warmed up!
I just bought a 1958 TR3A and it ran fair until it got warmed up and then
had incredible power loss--in fact we couldn't get it to run for more that
30-60 seconds and that was when really feathering the gas. I put in a new
ignition coil & fuel pump and changed the plugs. Now it runs even better,
great in fact, until it reaches just under 185 degrees on the gauge and it has
the same power loss--ie. step on the gas in 2nd or 3rd & it's just like
there's no fuel or spark--at lower RPM's ( & in 1st) it runs rough but it
runs. I checked the compression when it was at the temperature of the problem
& I'm getting 150 in each cylinder. I get 50 for oil pressure when it first
starts & then it falls off to a 40 at 2,000 rpm when it's warmed up. The
plugs for the back two cylinders are great but the front two are carboned
up---I assume because I was still pushing the gas pedal and it wasn't firing
cleanly. Again, when I let it cool, it starts & runs great. Any ideas?
