j9fd3s

ok so my tr3 has a pair of su's and the problem is this: intermittantly its got a big flat spot, and occasionally while driving it will "foul" spark plugs. i'm thinking its not really fouling the plugs but its not getting fuel. when i started it up a couple weeks ago #2 carb was intermittantly not getting fuel.



i rebuilt the carbs, but didnt change the needle and seat, cause i didnt have any tool that would get in there and remove em.



at this point i'm a little lost, although i know why they call su's constant depression carburators now
