How can you tell its a 43cc, with that photo. Some 43cc 40mm bore engines come with a 15mm carb w/ the 33mm bolt spacing. The 33cc is alot smaller looking and has a 13mm carb and 31mm spacing.
You need a V-stack on front of the carb to so you can run a 44mm ID Cag style hp air filter. The bore on the 49cc is 44mm, you can measure thru the intake or exhaust port. 40mm or 44mm, about 1/8" bigger, I can tell by looking in the hole and the thickness of the cylinder wall.

???! Mounting bolt spacing is the same on CN 26cc - 52cc.

Could be either a 43cc or 49cc, performance carburetors are the same for each. Bore diameter is the only reliable way of determining the engine size, especially on the 43cc vs 49cc. They usually had the same size of carburetor

The stock 15mm pumper carb, has a much bigger venturi than the 15.88 ( 16mm ) carb that has a 12.7mm Ven. Hugh might know, has anyone ever bored a 15mm hole piston and carb bore to 16 or 17mm?? I have aleast 4 of them carbs, and have ask myself that question many times when I was modding stuff.
