[TR] 61 TR3A SU H6 Carb Issues

Everything was running smooth before the rebuild. The choke wouldn't pull out easily at all and it leaked a little oil. So I decided to pull the carbs and install a kit as the seals were quite old based on prev owner service. I do have the stethoscope for the car to listen. I don’t think it is the balancing of air flow. With old cars, I know anything can happen somewhere else (points, plugs, wires, fuel, vacuum leak etc.) that can cause a new issue even if you didn't touch those systems. Looks like its time to test all systems again step by step.
Thanks for the note.

I'll chime in with another comment on carb issues which others may not support, but it was given to me by Ray Henderson (Triumph Experimental and Competition Dept). Before attempting any kind of carb adjustment, unless your valve clearances and ignition settings aren't exactly spot-on, you can have 'carb issues' which in reality aren't carb issues. The hose pipe to ear method for air intake volume may sound rather belt and braces, but it's a technique that's been used in the UK by mechanics on SU's (and later Strombergs) for at least the last eighty years! Sometimes the old fashioned way is often the best solution.

Jim - I'd check with a club in your area. See http://www.mossmotoring.com/british-car-club/ as a sample that came up in a search. There is an MG club in your city. Not sure if any of the Triumph clubs are near by. You might be able to find a local club member to help you out or recommend a local mechanic.
When I got my TR6, I went to a local British mechanic and he got the car better, but after just a few minutes with a very experienced club member, the carbs were great.
