I'm having fun with this - but if he has lost a critical component, it's really not funny.. He should not have gotten into the needle jet/emulsion tube/main jet assembly with what he was doing - only the diaphragm area (going to 1N) and the pilot jet area (going to a #40)..

Assuming he only did pilot jet and 1N - and it starts, idles, but dies with throttle -doesn't that have to be inoperative slide..?

 

*Update

I pulled the carb. Everything looked ok with the needle clip and washers. I decided to reglue the washers because they were slighlt off center. When I pulled the washers apart, I lost one of the washers. Couldn't find it. So I said F*ck It! I glued the remaining washer ontop of the needle and put it back together. I made sure the slide functioned smoothly. The float side looked ok too. I reinstalled the carb. BTW, I hate that boot. Almost as much as I hate the throttle linkage assembly!!

Well.....She fired right up. I mean right up. And she took throttle. I put the rest of her on and took her out for a quick rip around the block. Impressions? She feels stronger. The front tire leaves the pavement easier in 1st. No flat spots noted. What about the back firing? Well, it's between the same or slighly better. I think the #40 may have helped.

To summarize, clip on first position with only one washer glued on top has improved the power. The #40 to improve the backfiring at sea level may have worked. No idea why the bike wouldn't run right, but it is now.

Thanks for your help!!!

Well, I know what you said, but here's what I heard - "Blah blah blah, not going to tell you maggots what I did wrong, blah blah blah, go find someone else to pick on, blah blah blah, Ok, I forgot to turn the fuel petcock back on, blah blah blah...



Seriously, congrats..

If you have removed the air injection system, the #40 will certainly cure decel pops - usually @ approx 2 turns out near sea level..
The one lost washer may not cause any noticeable fueling issues - if so then I'd let-er-be.. But know that you now have .020" of sloppiness to the needle/slide "connection"..
You ain't the only one that hates that airbox boot..
