You can pull everythng but the EGR and the vacuum advance for the distributer. The tubes in the head are a pipe thread. 1/4 NPT, I think, but I would take the rail into the hardware store to match up for sure. Buy 6 plugs and lock-tight them in there.
Please, do the cruiser community a favor and keep the smog equipment together and sell it off as a package. 1974 F's (pass side filter) have somewhat unique systems and many owners in smog states (ala California) really need this equipment.
I would use anti sieze in the air rail plugs, just snug them down. the Allen head ones are better than square head if you can find them.
NO need to change carbs. Buy a package of vac line plugs. You'll like them better than a chunk of vac line with a bolt in the end. If you don't lock-tite the plugs in, be sure to carry a couple extra. I had problems with them coming loose.
Tell me if this sounds right....need 1 vacuum line from intake to distrubutor, one line from intake to throttle position diaphragm on carb, one line from intake to charcoal canister. From the Haynes manual and the diagram on here that is what it looks like but I guess I need reassurance. Thanks...
well, when we got our 74 (with 76 2f in it) I just said, well that doesnt need to be there. neither does that, oh and that too. I knew NOTHING about cruisers and it still runs fine. i dont think they are that picky
i took off the AIR rail and put in some pipe plugs we had laying around (actually dad got some more from work) they just screw right in. we didnt even loctite them and so far no leaks. we are doing the same thing on our 78. IIRC, i kept the dist vacuum advance, not the retard (mech told me retard is for retards) and kept the charcoal canister. also removed the air pump and plugged the hole for that on the air cleaner.
Don't get too happy pulling everything off until you know exactly what it was suppossed to do. Unless you are using an aftermarket carb. you most likely want to keep the evaporative emissions system, choke breaker, choke opener, positive crankcase ventilation and high altitude compensation valve (if equipped). Remember that many of the emissions controls on the 2F lean out the carb. so you will need to re-jet and readjust the carb when you are finished. If you have a grainger supply nearby the part number for the air injection plugs is #3P878, these ones are the inverted hex head and are made of brass, they fit very well and give the head a nice finished look.
