Just made an introduction, and this is a follow-up that's more technical and fuel-specific.
I picked up a 1976 C&C 27 Mk III that's been sitting in its slip for two years. The PO pulled the carburetor off for maintenance, and in the process broke the copper line between the electric fuel pump and the carb. He never got back to it and two years went by. So far, with the help of this site and the Moyer manual, I've determined that the engine is build year 1976, with the late model 5-bolt carb. The carb has an adapter flange to accept the scavenge tube from the bottom, and that port on the manifold is plugged. Don't know why. There's another hose that would exit that flange and hold a little aluminum cylindrical thing that fits in a copper elbow coming from the engine. Don't know what that is.
The crank turns by hand, and a compression test was consistent across all cylinders. My thoughts right now are: siphon all gas out of tank, replace the main copper supply line with A1 rubber hose, replace fuel filters. Then re-install carburetor, again using rubber hose to replace the little copper one PO broke, but with an inline polishing filter. This is all to make sure that the first time I try starting the engine after such a long rest, I'm not introducing ancient fuel to the system.
I'd like to hear any suggestions, warnings, etc. I promise to run the blower for a long time before pressing start.
Thank you!
