Hello,

I've recently acquired my Dad's old high wing trainer. The engine was ceased up so I took it apart, cleaned it out and put it back together.

I'm a complete newbie and don't realy know what I'm doing with this engine (OS FP35, probably 15 years old.)

There are three screws/needles to adjust on this engine - a big one which seems to control the fuel intake and two smaller screws near the air intake - one mounted horizontally and one mounted vertically. The longest I've had this engine running for is about ten seconds.

What do the screws/needles do?

How can I set this engine up?

Cheers in advance!
