Solo Bing Carburetor
1/10/112 Type SRB
- This is the only carburetor used on the US imported Solo's. It has both a spin off bowl and slide cover. similar to some "race style" motorcycle carburetors. It's small 10mm bore limits it's usefulness for performance applications. This same carburetor was sold from the factory bored out to 11mm. A 12mm bore is safe as well. Anything over 12mm will result in the fuel bowl vent circuit to become exposed. This can be fixed with epoxy. Theoretically it could be bored to a 14mm, although the slide it self is only 14.5mm and leakage of air around the slide would be likely.
Stock Main Jet #44-021/58
- This is the same jet as the one used on the common Puch bing carburetor. An entire range of larger jets are available.
Stock Needle #46-031
- This is the only needle produced for this carb.
Stock Needle Jet ## 45-141/2.12
- A range of sizes are still available.
