I started up a aTR4A that had been sitting for 10 years. Updated the ignition system and ran gas from a container....checked the compression and it was good.It started up OK. I had to have the choke pulled all the way to keep it idling and there was black smoke coming from the tailpipe. Not sure if the smoke was just from sitting so long or because of the choke being on. I'm an SU guy so not familiar with Strombergs. Is there anything I can do to set them up so I can have a decent idle ie. replace the diaphragm ,adjust the mixture? This car has frame issues so I'm going to sell it in the Spring and put the money towards my TR3. I don't want to get kits to rebuild the carbs...that's for the new owner, just want get it to run half decent. Is there one major issue with the Strombergs that I should be addressing?
