my BBD ssems to be the source of my trouble on mr "Road trip form Hell". i have it all broken down on the bench. seems the bushings i had put into the base plate have worn out already. is that normal? is that too quik? maybe they used bushings that were too soft? aside from that, i have 2 spares to work with. one i have gone thru already. it seems to be from a different application. i suspect an older one. it has a large spout for a vent tube above the meter rods. anybody know offhand what app this design was used for? is it an acceptable replacement for a slant 6, 225? one of the 3 has the hole in the choke plate. the other 2 don't. which is it that's correct for the slant? D~~~! |

What material are (were) the bushings you installed? Properly-installed bushings of an appropriate material should last many years. The carb bowl vent tube is present on some '70-up carburetors; other than that not enough detail to know what you've got. Send me a PM if/when you want a new carburetor. |

Rug. . . . i had the bushings put in at a local carb rebuilder. i took the shaft and the bash plate in and he made it fit real nice. SSD. . . . the bushings are the color of brass. i haven't had an analysis of the metalurgy done. thx for the offer of the "new" carb but i think not. i'd like to put a brans spanking new weber on the OBD but the 225 is 19 years old now. the compression is on the low side but still all even. when i wear it out completely i'll be looking for the Weber. sorry about the scanty info. haven't taken any pics of that carb. don't have a photobucket yet. where would such a vent tune be routed to? open to the atmosphere? D~~~! |

What year and model is the vehicle?
open to the atmosphere? |

possibly my throttle cable is pulling it wrong?it looks ok but maybe the geometry is off? i have this carb in a '68 A108 van. they never had the 2bbl in them. the original Holley 1bbl had a small vent hole on the top. it had no vent tube. which is the correct choke plate for the slant? with the hole, or without? D~~~! |

Don't worry about the hole in the choke plate; it's not a question of "correct" or "incorrect". Either works, it varies by carb. Yes, on a '68 you'd leave the vent tube open to atmosphere. |
