My TD's carbs have no piston lifting pin, just a hole to poke something
through. It's rather difficult to precisely lift the piston this way on a
hot engine. On the other hand, it's very easy to move the jet down by way of
the jet lever. Now it's said that lifting the piston weakens the mixture.
Lowering the jet would richen the mixture. Has anyone heard of a tuning
procedure involving moving the jet instead of lifting the piston? (I'm
thinking here something along the line "moving the jet down a certain amount
should have such and such affect on the engine rpm".)
Just wondering.
