Conversion for carb

My Walbro carb has a 24 stamped in the venturie. What size in mm is this? Also where can I get a new arm for the butterfly?

Thanks
Joel

Joel,
The 24 is 24/64th. It is 9.5 mm. It is a good choice for an 18 to 22cc engine. This is the venturi size (smallest section).

RE: Conversion for carb

What is the carb number. IE WT... or WA...? According to my formula you would want to try a carb in the 11 to 12mm range which would give you a venturi of 28 which will be cast into the carb also. For a carb arm you could use a steering nose gear arm. The arm would sit on top of the throttle shaft and be held in place by a socket head screw. There are many other ways too.
