Dellortos advice needed, Unable to adjust #2 cyl Options

[Localboy808]

This is my first set of Dellortos. Never even played with a set of Webers. I cant seem to adjust cylinder #2. Mixture screw can be turned in all the way and engine runs the same. If I pull the spark plug wire on #2 engine runs the same. If I pull any of the others engine runs worse. I changed the distributor and wires and did not help. Also checked my compression on all cylinders and they were even 115 - 120. These are new pistons and rings and havent run this enough to seat them yet. I'm guessing its fuel related. Is this a common problem with these carbs? My plan was pulling the jets out and blowing them out when I get home. Any carb experts willing to give some advice?

Thanks, Scott

Good idea on the spark plug. I've had some foul after a spark problem before. I'll try swapping it out tonight. I'll also look for that bleeder screw adjustment. I've been looking for videos on these carbs and havent found much out there. Nothing that went into balancing the two sides!

Thanks!

CB Performance sells "the Dellorto bible" with everything you need to know. It's a bit disjointed, and many pages are out of sequence (and some are redundant -- it's self-published) but it's a very good book to have if you're a Dellorto owner.

I went through that whole thing while I was rebuilding my 40 DRLAs and came to re-kindle the love with my long-lost inner-carburetor...though I do wish I could plug in the USB port and get some error codes once in a while...
