It gets cold in Florida?
Ditto on having the choke hooked up and functional, and don't forget that the Clifford manifold has no provision for manifold heat.

so the weather has been getting colder up here in jacksonville and the volare has been getting harder and harder to start, its getting so bad that i have had to spray a squirt of brake clean just to get her to fire up, and my god the cold off idle throttle response is terrible, stalling terrible till it gets sorta hot crazy 4bbl cliffy and 2bbl BBD, -Mike |

Got the choke hooked up to the BBD? ~RDE~ |

It's -5° C here right now, SuperSix, pedal to the bottom once, 2 sec. starter grinding, fires and idles like a kitten's purr.  Sell that Clifford to some California kid and get an Offy or a SuperSix intake. Haven't you a pile of spares laying about? Olaf. |

BTW: the fumes from brake cleaner are very bad for your health, when fired up they may be LETHAL! Take care, now! Olaf. |

I hear you Olafla. I don't think it is cold until it gets down to around 10 F or -12 C |

Volare4life: so the weather has been getting colder up here in jacksonville You sound like my son in Middleburg... [img]http://i294.photobucket.com/albums/mm87/wjajr/1967%20Dart/100_0768.jpg[/img] You can add a hydronicly heated hot-spot under the carburetor, and feed it from heater loop. I made this from a few chunks of ½†thick aluminum. First chunk cut like letter “Dâ€, second was a plate taped for two 3/8†90 degree hose to thread adapters from the plumbing aisle. [img]http://i294.photobucket.com/albums/mm87/wjajr/100_0835.jpg[/img] Sorry black hose over black headers over black engine makes a crappy visual, but the two hoses dipping under the manifold feed the hot-spot. [img]http://i294.photobucket.com/albums/mm87/wjajr/100_1006.jpg[/img] The guys are right, get your choke operating correctly. Clean all choke related linkages and check for freedom of movement of all related parts, and make sure all dashpots hold vacuum. You may have to convert to an electric, or manual choke where there is no longer a place for the bimetal spring to reside. Once you installed that Clifford, you defeated most of the cold start & cold drivability devices required for a four season conveyance. |

no choke has been eliminated, don't have my headers welded up yet, so i dont have the room for the "heater box", but more than likely thats what i am thinking the intake is not heating up enough. so time to finish up the header and make a nifty heater box, -Mike |

If this means you have eliminated the choke and no longer have a choke mechanism, then you shouldn't be surprised if the car runs poorly until completely warmed up. Chokes were invented for a reason.

If you can't run the water heated box as wjajr shows, Ford made a water heated spacer that fits between the carb and manifold. I have ran them on my SuperSix/Motorcraft setup and on my Offy/Edelbrock setup. They work very well and I have found them on the FE engines. |

I have no idea the vintage of Mikes Clifford manifold but some do in fact come with a water heated passage,mine does and it's several years old.Just saying

I should better explain. A hydronicly heated manifold won’t take the place of a choke. Heat is for unheated after market manifolds, such as headers, to provide better drivability, by preventing carburetor icing. Icing which can happen in the mid forty degree and cooler range under ideal conditions. Additionally a heated manifold helps to keep the fuel in suspension while traveling to the combustion chamber which is good for fuel economy. A cold engine needs an enriched mixture to efficiently & easily fire off, and to stay running until manifold & head warm up. You need to either install an electrically operated choke, or a cable operated manual choke to be able to reliably start your cold engine. Pumping & cranking over and over again to get it to run will just wash down the cylinders, cause starter problems after a while, and drain the battery causing added load to the charging circuit. I have an electrically actuated choke on a 4160 Holley. It would pull off way too soon making for a cold blooded beast of an engine. I installed a thermister, an electrical gismo that changes resistance as the head heats up, which slows the heating of the bimetal spring in the choke; in other words, the choke is slower to pull off. Now the engine starts easily, runs smoothly from cold to warm, and can be driven within a few seconds of a cold start without any drivability problems. |

no unfortuantly my cliffy is just a base 4bbl, no built in heater box, and no bungs for injectors, i have been meaning to swap my holley 4160 for awhile now with a 4 day weekend i get the chance, -Mike |
