HiI had to change the carburetor because the mower would only work on choke and would die on HI or LO positions. I didn’t change anything else. When I pull the lever out of choke down to the Hi position the choke plate opens fully (as per the swivel on the carb) the rpm is pretty much the same but when I put it on the LO position there is no change in engine speed. The motor is GVX120 4.4HP 1 cylinder.The governor arm is free to move but doesn’t not move the idle plate back and forth while idling. There are no restrictions either on the idle arm where the 2 governor rods attach on the carb.Any Idea?Thanks
Hi @jazzier Here’s the service manual that may help. On p.17 it shows how to adjust the idle and the governor. Hopefully this is of some help.
Did you replace the governor spring? Update (10/13/2022)
Check all the springs are replaced
