Hey Guys,
At work I have become friends with an older guy (retired mechanic) who has owned a 1976 Pontiac Bonneville 2-door hardtop since it was brand new. I guess it was one of four hundred which makes it a pretty cool car. Besides the timing chain and normal wear items the car is completely stock. It has a Pontiac 400 S in it and just turned 170,000 miles. This is a daily driver, not designed to be raced or even beat on. It gets him around town and is mainly a cruiser. The factory q-jet is starting to get tired and after quite a few rebuilds is starting to get more and more finicky (Runs rich even after adjustments, bogs a little, etc.). The guy really knows his way around an older engine and his rebuilds are COMPLETE with floats and rods and needle/seats, passage cleanings, the works, but we figure the carb just might be getting worn. The time it runs good before each rebuild is less and less each time. We are thinking of replacing it with a more modern carb but I figured why not get your input before so. I guess at one time he tried a Holley Economizer or something like that which I have never heard of but had problems and went back to the Q. He likes the Q but wants to see what else is out there I suppose. We are in Phoenix so altitude isn't a critical factor and the car weighs a few tons and has street gearing so I figure vaccuum secondaries are a must. We are not trying to get crazy performance, just a reliable carb that gets decent economy for what it is on. Not changing the intake so the carb needs to be spread bore. Any thoughts? Thanks a bunch.
