Triumph Repair: TR6 Carburettor, damper, oil
QuestionWhat type of fluid do you put in the carbs
AnswerIf it is the stock CD-175, a lightweight oil.
Some have used auto transmission fluid, and some heavier weight motor oil (30w)
It all depends on how fast you want the piston to move/react to throttle changes. Racers don't put any oil so that they get instant reaction, at the expense of the piston not have any smooth transition.
