OK, I have been tinkering with the new-to-me AFM on my 1911cc engine all weekend. I have adjusted the spring about 20 teeth CCW to get to this point.
I have been using an A/F sensor and gauge. can someone tell me, or direct me to a chart/table of what A/F I should be shooting for on my daily driver. The last adjustment of the CO screw has left me here: I have always had a strange idle situation, so lets ignore that for now. any normal adjustments to reduce the idle at normal operating temp eventually stall the car. A problem for another post. (IMG:style_emoticons/default/blink.gif) the idle is high.... at 1200 the A/F is a smooth 12.2. I found a long hill and drove up it at about 3800 rpm and the A/F was 12.5. thoughts? |

I do like welding stuff.... but man you can screw things up in a hurry.
Here is the result of my BUNG HOLE (IMG:style_emoticons/default/piratenanner.gif) (IMG:style_emoticons/default/piratenanner.gif) welding. It took 3 bungs and some patching of the areas I screwed up, but I am not too proud to show the world. Point of interest here. I did not really screw up on the welding of the bung to the pipe. I saw a YouTuber that installed the plug that is supplied with the bung. He then welded. His thought was to keep spatter off of the inner threads.... makes sense to me. Well the bung gets hot and ends up galling up the plug so you can't get it out. I ended up covering the hole with a small bolt dropped in the bung and a large washer. Repairs are complete, I'll add some Hi Temp paint to hide my grinding work and start working on where the wiring goes this weekend. Good garage day, it is supposed to snow in Nashville.
