It sounds like good advice. The symptoms you describe are exactly what I
experienced in my 76 TR6 a month ago, even slightly choking it as you did.
All I did was richen the mixture a bit and now it runs fantastic.
Good luck

Dick and all - thanks for the advice on the carbs. This is a "new" set of
carbs that I installed on the car. The old set worked fine but looked like
hell and there are no modifications to the engine since I switched carbs.
These carbs had been sitting in a box all wrapped up for over ten years.
They
look practically new. I had kits installed and plopped them on and hence
the
problem. I will make sure there are no vacuum leaks and then proceed
through
the steps of "tuning" as posted on the Buckeye Triumph web site (Thanks
Nelson
for passing that on to me).
