RE: K&B Carb?
[b]Ross:
The K&B 40 R/C engines have been supplied ex factory with five different carbs. Three were Perrys, the later K&B "Block" carb that had K/B on the front face, and the latest called the "Ribbed" carb, with the K&B inside an oval on the front face. The ribbed carb has been supplied in both front and remote needle versions, so I suppose you caould say six different carbs.
Two of the three Perrys look the same, but the earlier engines had a smaller spigot in the front housing, the earlier carb also had a slightly smaller throttle bore. If you have the earlier engine the later carbs will not mount. The third Perry is the pump carb, it has a 0.375 tnrottle bore, it wont work without a pump due to insufficient fuel draw.
Some people have cursed all of them, others such as myself have no trouble with any of them.
Just run it with the carb that's on it, nine times out of ten all will be well.
Bill.
