Nick. A C-75 becomes a C-85 by different carburetor jets and a bigger ventury.
In effect the engine will run faster and develop 10 horses more in calculation. Horsepower is a result of torque and RPM. To allow your engine run a higher rpm you need the right propeller as well. 2575 is the redline for a C-85. With a 71/50 you should be able to see that rpm behind a C-85. Your header tank should be removable sideways and down after removing all attachments bolts when no radios or instruments hinder its way. They usually do and one ends up tearing apart the whole panel.

If I understand, it is just mods. My log books make reference to my C-85 , but also mentions theC-75. The plate on the motor says 75. I need to know so I know what rpm to cruise at. I have a 50 pitch prop. Also , my header tank leaks (cracked at bend in rear)How do I remove it. _________________________________________________________________ Your E-mail and More On-the-Go.
