    And of course when you get it running again, be sure to get dad out and about!
    '74 TR6 CF13007U aka "Mr. T"
    Custom Blue (Delft-Like) and New Tan (Formerly Mallard and New Tan)
    Points, Ballast Bypassed, Bosch Blue Coil, Moss Cobalt Wires, Champion RN12YC plugs.
    Peaks and tweaks, but the spirit of Original
    Redlines always.

      Triple Webers will deliver TR6 nirvana in the right hands ( small club on this forum though - see the UK forum or TRIUMPH EXPERIENCE for a large one ) but if and only if the cam and head / compression ratio are P.I. specification or beyond; the U.S. market emissions spec engines won't make more HP unless supercharged. The Webers will outperform all but modern EFI systems which will only slightly edge them out, and that at the expense of the vintage nature the TRs so quaintly exemplify. I've done over 130K miles with mine since 1996 and will never revert to Strombergs or SUs for that matter. Nothing else on the entire vehicle is as reliable or enduring as these either.

      I reckon once you get it running as it did when new you'll be itching to get more power and torque out of it, if only to keep up with modern traffic. Check back then and Weber enthusiasts will be happy to advise.

        Been there done that on many TR's over the years. At least your gas tank was relined...hopefully the lining hasn't separated.
        I use a four step process:
        1)remove spark plugs and spray some penetrating oil into each cylinder. Reinsert plugs. Let sit overnight
        2)drain gas tank. Add gas
        3)change oil
        4)Crank over engine with coil wire removed until oil pressure rises. Reattach coil wire. Start car.

        At this point you can figure out what else may be needed (like carb rebuild) but until you get it started you won't know.

        I would suggest that history has shown many new owners end up digging deep holes trying to "revive" a car by jumping into the deep end and doing odd things that aren't relevant to getting it started. Including...."suspension bushings looked cracked so I better rebuild the front suspension before starting". These cars are often sold without much if any miles driven on them. Anyway, my point was going to be that many of the deferred or now needed maintenance items can be done once the car is driving. Way more motivation that way.

        These engines are not delicate, in fact they're downright robust. Waking one up isn't that big a deal especially given yours has low miles and known history when it was parked.

        Triple webers will not work on your car as is. Way to little compression. So to use the triples, you're gonna have to pull the head and have it shaved.
        On the 76 there's other things I'd eliminate at the same time.....the air pump, the injector lines into the exhaust manifold.

        That said, I think given the low mileage I'd keep it as original as I could. Lots of warmed over cars available, far fewer originals
