Title: OS40fp ABC vs. iron/steel
Post by: Steven Kientz on August 29, 2015, 06:33:42 PM

Picked up an Os40 fp today. Got home and compared it to my other one ,realized the case was different. It is the iron/steel earlier version(1986?). Is this worth working with or should I sell/trade it?

If it has a good piston fit it will be a good engine. See how it starts and runs.

actually, with my experience,, the iron piston version was actually a better stunt motor than the later versions
