Do you remember the topic, “Great Idea. Wish I thought of it,” it’s about the young lady who rebuilt carburetors (You should, both of our “fingerprints” are all over it, we both wrote several commented in there…)?
Where I wrote about the hassle I had with the carb on the '85 even when it was only 10-years old and even with the Toyota Dealer who freely admitted they no longer had any Carburetor experts on staff and could not even recommend a dependable one in town…
I ultimately rebuilt it myself from a kit that I bought from NAPA and it really was a nightmare. The instructions covered at least 4 versions of the carburetor (none of the illustrations matched exactly.
It was as if I had the 5th version that the kit did not cover…) and the only number that matched was the Engine Model “4A-LC.”
There were several versions of almost every gasket in the kit and I had more “unused gaskets” left over than I used as they were not for my specific carburetor… It was almost as if the carburetor was “Body Color” dependent… Red got one carburetor, Blue got another…
Here is my posting and the funny thing is that it is a response to you… L
