[TR] Webers on my TR4

[Lee&John Howard]

Good ideas.
I never added the fuel pressure gauge because, well, it was working fine
without it! I have checked the filter screen and it was 95% clean.
Condenser is a god idea and might have gone coincidentally with my screwing
around with the fuel lines, I guess.
I will pull the jets, but don't see how anything could get by the fuel
inlet screens.
Incidentally, your Weber site is a regular reference for me. Thank you for
that.
