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? |

OK I am beaten! Maybe it is just me but I have redone this carb 5 times and it has never been right. Ran a little better each time but never right. So I replaced my pride with my wallet and got a set of dual 44s.
While I know I now have a new set of problems to sort I am hoping that will be more predictable. If not, then I have a very expensive set of carbs sitting on a bad engine. Anyone interested in a single carb set up with lots of new parts but still won't work? I bet I could make you a deal! |
