Agree with W8YE, I have several of these little gems and the carbs are interchangeble with the LA. Only major difference is the LA has rear needle and the FP has the needle on the carb, but both are air bleed idle, simple and reliable. The LA manual for break-in and engine adjustment has worked fine for me, but this engine is so simple, who really needs a manual???

Note; I had one with a Macs muffler on it and it would spin an APC 12.25X3.75W prop on 15% nitro without a problem. They breakin very quickly and are easy to set the carbs on.

Have fun with it.
