i have a Tillotson HS-176 carb with governor that wants to go lean at full throttle. It starts out four stroking and moves to a lean condition after a second or two.
Here's what I know
The governor is blocked off.
The throttle shaft is not worn
The carb has been tried on two saws which have both been pressure and vac checked and both are good
The saws run fine the the 176's ungoverned brother, the 168.
New kit in the carb didn't help.
The carb was cleaned several times with a US cleaner.
Any suggestions would be appreciated.
