I have a Weber 32/36 that I purchased from WeberCarbsDirect.com. Here is a picture with a logo.
Does this mean I have a "fake" Weber? I remember reading on one of these threads where the carbs from Weber Redline were real Webers and the ones from Weber Carbs Direct were fake. And that the real ones have logos cast into the metal whereas the fake ones have a label.
The reason I bring this up is that it failed emissions today here in Texas. HC level was to high indicating it's running rich.
Whenever I run the lean best idle procedure I run into the situation below in bold:
"If the mixture screw is more than 2-1/2 turns out turns then the Idle jet is too lean (too Small). When the mixture screw is less than 1-1/2 then the Idle jet is too rich (too large). These assumptions are based on the fact that the speed screw setting is not opened more than 1-1/2 turns. If the speed screw has to be opened 2 or more turns then this is also an indication of a lean condition usually requiring greater change. At times it may appear to be showing signs of richness or flooding it is really a lean condition. "
So, the carburetor has always run well, but no matter which idle jets I put in I can never get it to run with the speed screw set at 2 turns or less. I think technically it's running lean but I'm having to compensate by having the plate opened up dumping more gas in. My theory is that this is why I have high hydrocarbons.
Bottom line, the reason I asked if my carburetor was not a "real" Weber is that I'm concerned this carb isn't right and I'm never going to get it zero'd in. Perhaps I should bite the bullet and replace it.
I think after having this carb for 2 years and rejetting it multiple times, I'm going to go with the motor craft. It runs good but I've never gotten it optimized per the instructions and now I'm flunking the smog check.
The bad thing is it's the last smog check it will ever need since in TX it will be exempt when it turns 25.
