Dist should go to rear of carb base but can also go to intake. large fitting at rear goes to brake booster. There should also be another large one for pcv valve.There other ports that supply vacuum to accessories options. Some ports on that carb are above throttle plate and only give vacuum at times when throttle is open. anything that needs full time supply should not be connected there.Block off all unused ports.

    ps: what's the carb sitting on top of?

  • Richard Scordino Feb 07, 2009

    There is a 307... no 305 as far as I know (used to build chev racemobile engines) Don't do too many burnouts with that one or you just may spit the crank out the bottom!!! (cast crank & not very big main journals) Good grocery getter... only problem with with the early ones was soft camshaft lobes. other than that, still better than just about anything else out there... Too bad its not a 350! I'm getting ready to put some really good cyl heads and stuff up on craigs list!
    Good luck with it!!

I have a gmc truck with a 351E v6 it will not idle there is a line opening on the back of the carb plate and a small line that comes off of the left side of the carb. Where do those lines go to? It is not...


I don't have a diagram but I think the replacement carburetor may have come off an engine that had a governor which was activated by a plunger under the distributor plate. The vacuum lines went between the carburetor and distributor. Check to see if there is vacuum at one of the lines when the engine is runnuing. If there is just plug it off. A vacuum leak could be causing your idle problem.

Need diagram of 84 Mercedes 300cd ignition switch. engine does not shut off when key is turned off.


sounds like a bad vaccum line at the key barrel... the old mercedes had vaccum accuated key barrels and with no vaccum the engine would stay running... check for the lines near the key hole and follow them and inspect as you go.

1987 chevy s10 will not run. changed weak fuel pump and prssure is fine now, swapped out ecm, replace fuel pressure switch, oil pressure sensor, distrib cap, rotor, elec chip on distrib, o2 sensor, map...


It does sound like a fuel problem, try running some jet cleaner through as you may have clogged jets. Sometimes, removal of air filter and placing the palm of your hand over the top of the carb's butterfly valve, will clear blocked jets when engine cranked over a couple of turns.
Also check the float valve is letting fuel in, could be stuck.
I hope this helps.

Check your MAP and TP sensors. Your throttle body may be having trouble determining position and is compensating by adjusting RPMs.
