I have recently purchases an 084 fitted with a tillotson HT-2 Carb. the carb seems to be over fuelling the saw even at its leanest setting. I believe these carbs have a second high speed circuit. My question is, has anyone else come across this issue before, and if so what was the solution? I have swapped a Carb off a different saw onto it and it runs much better with no rich running issues. I also have a carb kit on the way, but it wont be here for a week or so.

HT-7A. They are fully adjustable.

Also check your metering lever level.
Could be the problem

Metering lever is too high or the diaphragm is old and stiff holding the needle open.

They have a fixed nozzle in the carb, very common. Even closing the H needle it still overfuels as a method of limiting rpm.
