Hi everyone, I have an older Lawnboy (model 5126) that will only start if I shoot a bit of lighter fluid/carb cleaner into the carb. Here is what I have tried: - Emptied the floatbowl and cleaned it - Removed the main jet and cleaned it with carb cleaner (it was pretty plugged) - cleaned the air filter - removed the fuel filter (very temporarily to ensure it wasn't plugged) I have taken the carb off a few times to work on it. Everytime I have done this the float bowl is full of gas so I know that gas is getting to the carb. I'm sure that I haven't adjusted the jet properly since I took it out to clean it. From my understanding the adjustment of the jet would not impact starting. It only kicks in at higher RMPs. Am I wrong? I also noted that the spring is broken on the "air vane". To be honest, I'm not sure what that spring does. Moving the air vane still opens/closes the butterfly valve in the carb. However, moving the throttle control does absolutely nothing because it is not connected to anything anymore. I ordered a spring for it but would this prevent the mower from starting? Thanks for all of your help.
