<span style="text-decoration: underline">Car</span>: 1974 TR6
<span style="text-decoration: underline">Problem</span>: Weber Dual DGV downdraft carb conversion completed on rebuilt engine, car is backfiring through carbs and stalls at stop. It also seems to be burning rich as the fumes waft back to me while driving. Adjustments to the carbs don't seem to help. My TR6 experience is limited, but I can't believe it normally runs so rich as to smell raw gas.
<span style="text-decoration: underline">Research</span>: I did a search of the site but could not find an answer. I also searched the www and couldn't find the exact answer.
<span style="text-decoration: underline">History</span>: I have been in here before whining about this, and thought I would redo the distributor and hot things up. I didn't do that because I wanted to understand what was going on for a change. After reading all I could, my vague understanding is that the problem is with the carbs, so I didn't want to add changing the distributor into the mix of problems. I tried adjusting the Webers, and so has my mechanic.
<span style="text-decoration: underline">Advice received</span>: My mechanic, who I think is a mechanical genius, tells me I haven't run the car enough since its restoration and breaking it in may solve the problem. Maybe he thinks that after the engine has a few more thousand miles on it, the the carbs will work better.
<span style="text-decoration: underline">My opinion</span>: Okay, I am a complete idiot when it comes to mechanics, but it seems to me that a break-in should not be necessary. I think it might be in the porting.
<span style="text-decoration: underline">Help</span>: Does anybody know of a shop in the tri-state PA-NJ-NY area that is expert to review and fix this problem? (Assuming that my mechanic is wrong and all I need to do is drive it a few thousand miles)
Or should I buy a new W-DGV kit and try to do it myself and hope I get better results? There is one on eBay that is a complete kit with instructions. (This probably isn't the best solution - I set things on fire)
I'll be coming back to the U.S. in May for 12 days, and I would like to spend just one day getting this to work right before I head to St. Louis to pick up a hardtop I purchased for it. I am afraid the plugs will foul before I get halfway there.
Thanks so much for your help as we approach sports car season. - Dan
