Here's where I'm at right this second. Impatient & frustrated yes. Stupid and willing to make hasty decisions? No.
Save an internal problem of low compression, or some little electrical wiring bugger at the coil.. we've essentially eliminated everything but the carburetor. I can do one of three things to troubleshoot that.
1. Take it to my local mechanic and have him run the gamut of diagnostics. The only way he's gonna find the carburetor at fault is by bolting on another proven carburetor, right?
So he buys a new edelbrock 1405 and installs it.. and tunes it.. and she runs like a dream; in the end 3-4 weeks later I have a shiny new bill of at least $1,000.
(plus the front end alignment he was originally slated to do= $150).
2. I find a proven carburetor myself right now, whether it be a 1405 new in box for $300. or another Carter 4299s in good condition (ebay or forum members shelf? I just saw a good one on ebay for $50, then find a "better" shop to rebuild that?)
I then install the new carb myself and get an answer.
3. Remove the original 4299s and either a) send it back to the original rebuilder to go through it and if possible, make it right. or b) send it to a different, more reputable guy to rebuild correctly.. hopefully one who easily finds what fuckery lies within. Both of these options possible only if rebuilder a) hasn't already permanently screwed it up.
I have already figured out and done the work myself on several systems here over the last two years. I replaced the fuel tank, fuel lines, fuel pump, fuel filter, and reinstalled the carb right after the rebuild.. yes, all by myself. I rebuilt the master cylinder(granted the cylinder was sleeved by a machine shop, but the new pistons, valves, brass seats, springs, etc. were done by me.)
So why shouldn't I get a working carb, (max $300 for new), install it myself within an hour or two, and have my answer right there.. all in one day, from store to car???
