HP 40F - RC

Postby dmacpherso » Fri Mar 09, 2007 9:04 am

I have had this engine since 1975 but have never used it. I'm now ready to use it on a SIG Kadet plane. The engine instructions seem to be missing a page. There is no carburetor shown on the engine. The carburetor which came with the engine has a needle valve and an idle adjustment screw. However, there is a third adjustment screw which isn't even mentioned in the text of the instructions. The instructions which I have are labelled HP-Motore 1974-1/E-1. Can anyone provide einfo on this carburetor?
