I"ve received an older Fox Engine but it is in new condition. Idon't know where to start with the low speed and the hi speed. It says Fox Eagle on the side of the engine. Both adjustment knobs are fairly large by todays standards . It looks to be at least a 50 size engine. Your help would be appreciated. Thanks Flybye

Most likely it is a .60, is the lower crankcase one piece or two not counting the cylinder which bolts onto the crankcase.? Can you supply a Pic? Thanks.

The crankcase on the left is the Eagle 4 crankcase.

It is definitely the large three piece onthe left in the pic.. It sure looks like a healthy son of a gun. Thanks for your reply

Your fox should behave on 0% or 5% nitro. The carbs are often blamed for problems but keep the nitro low and you should get it tuned. ID your carb of the above site and follow their instructions. I like my Foxes.

Many thanks guys! With Hobbsy'sphotograph I was able to determine which engine I had. and with Badger's website referral I was able to print up the entire manual on acrobat reader. I never would havefigured that one out !!!

Fox makes the Eagle IV in two displacements, .60 and .74. They also made the .60 in ABC as well as ringed. The .74 is currently made only in the ringed version at present. I am not sure, but I think they made the .74 in ABC as well and discontinued it early on.

RCFly sed that
d:^)

RC, I have a Dieselized .74 ABC and a Dieselized .60 ring as well as glow versions of each. Fly will have to measure the bore to be sure but if it isn't stamped into the crankcase it's very likely the .60.

If the engine is ringed and hasn't been broken-in completely, be prepared for a long and tedious break-in trial. The websites mentioned should get you started on the break-in procedure. Follow it and don't take short cuts. Peaking out a ringed engine too soon can result in losing the tension in the ring's metal and require replacement. Not all that difficult to do, but then you are back to square one in the break-in process.
