I have a 69 TR6. I read Part 3 of the Buckeye Triumph article on tuning the carburetor. I am only on the second page. I wasn't able to get my car to idle smoothly at 900 RPM, so I went through his checklist. I found one of the elbows in the vacuum system split from the bottom (couldn't see it from above at first), and three holes in the rear carb diaphragm. The rear carb had black soot inside, but the front carb was clean inside. So, here are questions I hope someone can answer for me. 1) What would cause the black soot in the rear carb? 2)I put in a new diaphragm in the rear carb, but the air valve does not drop "with an audible click" like the front one. It did this before and after I put in the new diaphragm - any ideas on why? 3) I need a posidriv screwdriver for the top cover on the body, and the posidrive screws that hold the diaphragm sealing ring. Who carries these and what size would I need for each? Any suggestions are always appreciated.
