McCulloch 4 Cylinder 2 Cycle Drone Engine. Here are the specs:
Model Spec 0-100-1
Ser. No. 43124347
Contract No. AF33 600 266
Timing BTC 25
The propeller on it is a US Propellers Inc. Model 22008 Ser.No.YY254
Prop has a very small nick or piece missing on the edge of the blade about an inch long but looks as though it wouldn't effect its operation at all.
I've owned this motor for just a year and I've decided to sell it as I'm cleaning out the garage to make room for more stuff I'll never need so check out my other items for sale, lots of engine stuff. Engine ran good when I bought it, I never ran it since, its not locked up and has good compression.
Selling as is, No Reserve, prefer buyer to pick up but I can help with shipping, questions gladly answered.
