Conversion of C75-12F to C85

The part numbers are 40487L, 40487R and 40488 and yes these are applicable to all C85 engines but not required on all C85 engines. The parts book is a list of applicable parts not a list of required equipment. The TSDS is and it only requires those baffles with the Beech prop.

The Ercoupe Parts Manual calls for 3 baffles each with it's own part number. All models with C-85 engines. I will dig out the part numbers and post them.

The extra baffles are only required with the Beech controllable prop.

A couple of engine baffles also need to be added.

The wide trim tab is not required. A trim tab is required but either the 3/4 inch o1-3/8 is acceptable.

I understand that to convert my C75-12F to a C85 hp the main thing that needs to be done (besides having the correct prop) is the following:

The carb need to be changed to a 1 3/8 venturi and the metering jet to a #45 size jet.
22031-4 TRIM TAB PLATE - 1 3/8" WIDE (Required for C-85 Engine)

Have any of you had that done? If so, how do you like it? What are things to consider? Etc.
