Anyone have anything positive so say about these things? It looks like my choke is all screwed up from this thing. The previous owner of my car had a Cool Carb heat shield installed on the car as he stated he had issues with the fuel getting vapor lock. I've heard both good and bad about these things, personally, but I don't think its worth having. It gets hot here in Long Island, but not for long. Also, I've been running 93 and adding TC-W3 into my fuel, so I don't see vapor lock being an issue anymore. I've also sorted a lot of issues to the fuel system that I found were all wrong, so fingers crossed, I won't see vapor lock in my future.
With the plate installed, the carb (Carter AFB 4200) sits about 5/8" above stock height. On the carb, the choke operating link was bent to **** because it looks like whomever installed this plate tried to compensate for the new carb height by working that link, instead of the divorced choke mixture adjustment.
My issue at this point is that she starts great... warms up no issue. Kick off the choke, good for a few minutes and then she start loping like I have a huge cam in it, then dies. After sitting a while, very hard to start. Smells like it's loading up. Finally when started... I'll be driving it around for a while, pull up to a light and sometimes the loping starts again. Sometimes no issues at all. Sometimes I'm running at fast idle. Car runs great on straight throttle... but hit it for kick-down or fast acceleration... nothing. I've opened the hood to check the carb while it was loping and I could see the choke diaphragm pulled in and the choke on. I've adjusted the mixtures per the FSM, no help. I've had it where the choke reset itself as I pulled up to a light and I'm sitting at fast idle trying to kick the thing off.
The reason for the rebuild is that I can see the top plate gasket is leaking like a sieve even after I've retightened the screws. I figure a good cleanout and a re-gasketing won't hurt anything but my pocket. I took off the carb off and will be sending it to Dana for a rebuild. In the meantime, I really don't want the Cool Carb plate on the manifold anymore. I'm going to ask him to replace the bent choke link, or bend it back to normal stock position.
I'm looking at making this all OEM and getting it back to square one as this plate seems to be causing more aggravation than it's worth having installed. I'm pretty sure the height and the screwed up adjustments are causing the problem with the choke. Does that sound about right?
Thanks.
