Adjusting the Edelbrock

Owners of the Edelbrock Quicksilver II carbs:

Did you guys find that the carb came adjusted pretty well out of the box (besides idle)for an uncorked 650R? Or did it take some fiddling? Also, did you leave the adjustment tool on top of the carb or take it off? Thanks!!! Lee

You may have to do some adjusting for optimal performance, but it should run well right out of the box the way its setup if you bought it from Barnums. Most folks leave the adjustment tool installed all the time. Just install it the way you get it and don't forget to turn up the idle enough, then she should fire right up in a kick or two.

I left my adjustment tool on. The carb came very close to being adjusted. It was a little lean and I had a hard time starting mine but I had the idle way to high. Backed off the idle and richened the needle a few clicks and it was good to go.

i got my carb from rob barnum - it came with the 19 needle, 18 clicks from full rich and 2 turns out on the pump - after playing with it for a day or 2 i have it set up - 19 needle 12 clicks from full rich and 1 1/2 turns out on the pump (like the spec sheet that came with the carb says?) my bike is uncorked, HRC tip, holes in the airbox with a uni filter - she runs like a raped ape now - i just wish i would of put the carb on when i first bought the bike

i left the adjustment tool on also.

Thanks for all the input guys...good stuff. Just put it on yesterday. Initially I had trouble starting it but that was because the idle was too low. I'm officially a believer now! It's only taken me four years. That carb flat rocks! I can't believe how much "smoother" it makes everything. No more delay, hiccups, burps or protests like the stocker. Not to mention throttle pull is much better. 2 blips 1 kick.

John-

I have been reading your posts about the edelbrock--i have had similar things happen. I found the little brass needle valve in the AP 'chamber' was sticking--and so little or no pumping...if i was you i would focus on that first. They do seem to wear a bit-so look at the pointed end of that little brass valve (it slides right out of the hollow chamber) and see what condition it is in. Any little wear marks? Dirt? etc.? Thats the area to focus on first.

For some weird reason i cant log onto the current 650/600 posts-and only on occasion onto the older posts--so i cant get to your current post about the carb-but wanted to try to help out...plus i am super pissed off at the Yahoo site right now and avoiding it!!!!!!!! (but we all know how i get this time of the month...:thumbsup: Maybe i am black balled from the current 650 forum?!

ANyway-get that brass valve moving smoothly up and down and your carb adjusted and it will run great. Try the 17,18,19 needles with all your engine mods!

Hey Mike...

I saw the posts on 650R forum... man, I was gonna chime in but decided to stay away. :thumbsup: Anyway, that little brass thingy is missing. :devil: No worries about it being worn :awww: I don't know how... or why... but I'll be ordering a new one on Monday.

Thanks for the help... I just happened to look on this thread and saw your post. Very cool of you! :lol::D
