I have a FJ40/2Fmotor, smog removed, all extra vacum ports plugged. I installed a weber 38mm carb The first week it was great. I then had to lean out the carb. This worked great for a bit. At this point I am still running slightly rich and the carb will not lean out any more.
The second issue is when I climb very steep inclines, or over high angled rocks I stall...it appears to flood out ( when trying to restart I get black smoke out of the exhaust)
Now I realize there are many variables to a motor properly being set up. Here are a few of the tweeks I have done before the carb was installed, adjusted the valves per spec, new plugs, new rotor and cap ( no points), new fuel pump, new fuel filter, gas tank removed and checked for dirt ( none found). I have re-check after 8 weeks of the carb installed, valve clearance, new plugs ( old ones fouled a bit) tried to lean carb ( no avail)
Once the engine is warmed up it "seems" to run very well accept for the two issues above. Meaning when the engine is hot it burns the gas better...
Can you point me in the right direction Why can I not lean out the mixture anymore? Why would the carb flood going up very steep inclines? ( if in fact it is flooding) or do I need lower gearing?
I live at 4500 ft - Thanks for any info!
