Steven: The Zenith carb is one I purchased from Moyer. I equipped it with an extended idle adjustment screw, an adjustable main jet and quick release ball joint cable connector. I used this carb as a quick switch out when I was dealing with dirty fuel from an old galvanized, varnished up gas tank. When one carb would get fouled I would take ten minutes and exchange that carb for a clean one. I'd then take the dirty one back to the shop to clean. I did this to get through an entire sailing season until I had the chance to tear out the old tank and install a Moeller tank.
I once had a spare engine I picked up from a local guy switching to diesel. The new, in the bag from Moyer, adjustable main jet kit was for the carb on the spare engine. My brother-in-law talked me out of the engine before I started to upgrade it.
The mechanical fuel pump is the original from my 72' E27. I upgraded that A-4 with an electric fuel pump, electronic ignition, coolant by-pass kit, exhaust pressure gauge, external oil filter and oil pressure and temperature alarms. It is in good condition but a candidate for a rebuild. Those housings are getting hard to come by.
The manual is a Moyer. Clean, no grease smudges.
The tranny cover gasket is a spare.
The crank is a Moyer. Used only twice for ignition and valve timing adjustment. That has been spoken for.
I've posted these for sale on the SBO forum. Prices are listed there. Let me know if you have any further questions. Al Frakes
