Yea it is kind of a waste (Weber 36/38 DVG) but I have a number of projects that are sucking up $$$ so I am trying to make it a while with this set up. Had a huge stumble before changing to the 60s on the Accelerator jets. The stumble is mostly gone now. Waiting for a 70 to come in. But while its better, it seems to not want to idle. Regardless of how I try to adjust it acorroding to the instructions, it seems to want to die. At anything above idle it seems to be fine. The problem was there before the change but it was no better after. Did a good cleaning on everything else but did not change anything other than the accelerator diaphram. One thing I noticed is that fuel seems to be dripping into the primary. I am not sure if it was like this before as I had not looked in.
I am assuming this is not normal, so any thoughts on what I goofed up? |

Wow that is some great information. I just quickly read through that but it seems similar to the Weber lean adjust procedure. But it is explained 1000 times better!
Went through the carb tonight comparing what was suppose to be in it stock compared to what is there now. There are so e notable differences that I will post but I have verified that all of the parts are in the correct place. I did note that the primary idle jet o ring had become frayed and some small parts of rubber were on the jet. Cleaned everything and put it back together to see if that was the problem. What I need to do is pitch this thing and get a new one. But I just hate to think this thing can beat me and I am learning a lot thanks to the posts I have gotten on this. So thanks to everyone. |
