Small Engine Repair: Adjusting the low speed carburetor circuit on a Ryobi Blower

Written By: Leaf Blower Guy - Apr• 11•13

**Always follow the instructions in your repair manual when doing repair or maintenance work on Outdoor Power Equipment. Manuals can be found at the manufacturers website.** This video is about adjusting the low speed carburetor circuit on a Ryobi Blower. On this particular blower the low speed carburetor circuit was adjusted to lean, so the blower would stall when you tried to accelerate the blower from idle to full rpm. The low and high speed adjusting screws on this Ryobi blower use adjusting screws commonly referred to as pac-man screws. Adjusting tools can be found on ebay. Tools Used: – Pac-man tool driver

    @oabus Not sure, but when i bought the tool it was part of a set of 4 drivers. If you look on ebay you will see what I mean, and one of those tools should work.

    I learned something today Thank you. I have a sears blower that looks almost identical to the ryobi you were adjusting. Is the pac-man tool you were using going to work on the craftsman. the model number is358.794765. Its rated at 450 CFM.

    @ahmedzs74 Than the engine probably isn’t getting fuel for some reason. Check everything related to the fuel system. Start with the simple things first…..
