Folks, I am a new owner of an early 1974 TR6. Car was in storage, dry garage for 28 years and basically unmolested, she has 28,000 miles and the original Stromberg carbs. Since bringing her back to life, fuel tank was flushed and a new fuel filter added, new plugs, wires, distributor cap, points and condenser installed. Car fires up cold every time with a little choke and runs great for the first 5-10 minutes. Then the idling gets rough/low and will eventually stall out while waiting for a light to change or at a stop sign. The car will not re-start, typically have to wait minimum 30-60 minutes until it will re-start and the process starts over. I have ordered a new ballast coil (set to arrive today) and a carb heat shield based on other articles of "possible causes." Any other suggestions or culprits that I should explore to resolve? Thanks.

Is there any debis present in the new filter? Have you checked the fuel pump's internal filter?CF1634U+O Pimento/Chestnut

It doesn't sound like it's a heat issue if it begins to act up after only 5 or 10 minutes of the engine running.
How about flooding ? Have you investigated that possibility ?Driving a 1973 TR6

Since the car sat for so long, Pop those carbs off and send them to Pool Boy...it will be money well spent ! (see Ken's contact info above)Comment

Open the gas tank filler cap and see if it continues to run. If that doesn’t help, send the carbs to Ken for a rebuild. They’re probably all varnished up inside.Last edited by lfmTR4; 04-20-2023, 06:29 PM.72 Pimento w/overdrive - Lilred

I think the fuel bowl vents to the carbs are covered or blocked. How about removing the air filter assembly and seeing if a gasket or gunk is covering the fuel bowl vent? The vent is at 10 o clock on the face of the carb.
The bowl can't vent so a vacuum gets on the fuel and therefore it can't get pulled up through the jet. Sitting for 30 minutes allows the vacuum to go away and fuel can go up the jet.
This happened to another member a few years ago who made his own gaskets and covered the hole.1972 Sapphire TR6 #CC84,something

See what the new coil does. The coil for the 74 unmolested should be ~1.5 Ohms'74 TR6 CF13007U aka "Mr. T"
