LookingUp Posted March 20, 2018 Share Posted March 20, 2018 (edited) I've been having some difficulties with my motor. It is a he r120 with wg8 carb. I was unable to get it to idle and after switching off it would pour petrol out into intake. I have stripped the carb and cleaned and I am replacing parts with kit k12-wg. I noticed when disassembling, the metering lever was firm on the pin and required some force to move it. I assumed this being tight was the reason for over fuelling. Should the lever be free moving on the pin? Should the screw that holds the pin down allow the shaft to rotate? I can't find any answers on the walbro manual so would appreciate a little advice.

noddyc Posted March 20, 2018 Share Posted March 20, 2018 If I am correct the pin is screwed down with a screw on the one side , that would mean that the lever must be loose on the pin. That is how the walbro wb37 carb works Quote Link to comment Share on other sites More sharing options...
LookingUp Posted March 21, 2018 Author Share Posted March 21, 2018 That's what I had assumed but wanted to confirm. It should be free to rock on the pin (I ended up having to loosen the lever where it slides onto pin) Thanks for the reply. Quote Link to comment Share on other sites More sharing options...
GR002 Posted March 21, 2018 Share Posted March 21, 2018 The lever should be free to rotate on the pin. you should not have to slacken screw that holds pin. Quote Link to comment Share on other sites More sharing options...
