Hi Folks:
I'm a TR6 driver (former Midget owner too! ) but was helping a buddy with his 1976 single-carb Midget tonight and I brought my Moss mixture adjusting tool to see if I could help out with his carb problems. I know my way around a Stromberg fairly well and how to use the tool but the metering needles on my TR6 move easily with the tool and his just doesn't want to move and although the Allen key fits the needle, indicating that it is in fact an adjustable version I am hesitant to apply too much pressure. Can these needles get gummed up with carbon or varnish requiring the carb to be removed and soaked in cleaner (Gunk) or can I just horse it loose? I know enough to check all his vacuum lines, diaphragm and bypass valve but I'd really like to see if it's running rich first, which it appears to be judging by the sooty plugs and the exhaust and I really don't want to bust a buddy's carb by forcing the needle. Are they pretty robust or should we take it off, soak it and just rebuild it - any suggestions?
Cheers,
