rebuilding wt253 for a stihl bg72 blower. checked the nozzle assembly by blowing/sucking through a piece of fuel line. no resistance either way. I'm thinking its the check valve. if so how do I get the old nozzle assembly out?
I assume they install the same way. any sealant necessary?The main fuel nozzle just presses through into the throat of the carb. You need to unscrew the high speed mixture needle first and then press the nozzle through. Some people use a drill press to push them through. i just use a pin punch and hammer. They push through at a bit of an angle and not square with the carb body.
I'll have to order this and see if it is any good.
