Default Fox Eagle 60

Can some one identify what Mk this is please? Is it a good diesel conversion candidate?
Thanks
Joshua

Fox experts will no doubt chime in and correct me.

The slant plug indicates to me that it is a baffle piston engine which makes it an Eagle 2. I believe the Eagle 3 was first of the schnuerle 60's.

Lovely engine though! I would like one for my modest collection of classic 60/61's.

Oh, and the baffle piston rules it out for diesel conversion for all intents and purposes.

It is a Fox Eagle I engine. It is a loop scavenged type of two stroke engine that uses a baffle on the piston to help control the intake charge forcing it to loop up over the baffle and not go out of the exhaust port so much. Unfortunately because of the baffle they make for poor diesel engine conversion prospects. the baffle tends to get too hot resulting in pre-ignition or detonation issues as a diesel. Now there have been a few model diesel engines that had baffles, but they are very few, but the baffle tends to be quite small. The other problem is the baffle interferes with a contra piston that you adjust up or down. So you have to have a contra piston that doesn't rotate as you adjust it in or out. In the past, some of the vintage model diesel engines had a notch cut out of the piston so that they could keep the flat top on the piston crown and have something like a baffle to direct the fuel/air charge in a loop up and over.

The Eagle II, II and IV engines are all Schuerle ported engines and more or less, have a flat top piston crown and they make excellent model diesel engine conversions. Davis DieselDevelopment makes diesel conversion heads for these engines too. The Eagle IV engines are of course the best for the conversion to diesel. The Eagle I is a nice engine and ran as good as all the other contemporay engines of its type way back then. But not as a diesel though.
