adjustment

I have an old 440 that I just made a 440/460 hybrid. I put a brand new carb on it when I did the swap because when it was just a 440 I couldn't ever get the carb adjusted correctly, or so I thought. The 440 piston was also absolutely shot so I never really thought about the issue being anything...

I have a Homelite XL-924 that I can’t get to idle and keep running! Here is what I know: -It has spark + brand new spark plug adjusted with the correct gap -145 psi -Exhaust baffle has been grinded and is free of any build up -Brand new fuel lines. Carb is pulling gas. Running 32:1...

I’m trying to adjust the carburetor on my MS461 and I have 2 problems: 1- I cannot lower the RPM on full throttle below 13800. 2- when the saw is idling (2800-2900rpm), the chain run a little bit (it moves a inch every 1-2 seconds). Is that normal? Thanks

Hi.I have a Husqvarna 236 recently rebuilt, but i have an issue.Saw starts only with choke once it's hot.Should i tune the carb again?Wich screw?
