well i dont know alot about this carb but i have one. does any one out there have any info or know where i can get info on them? i know that i has a realy stiff throttle and i dont like that(even stiffer than my banshee)and i dont even know if it is jetted right. if any one can help it would be appreciated.

thanks

 

I have one on my 400 and really like it!! The altitude compensation feature seems to work very well (probably not something you'll need in Texas). The power really hits hard in the mid and high range, but I can't say I gained much low end. Never felt that the throtle was stiff either. Anyway, call Edelbrocks tech service. The guys there are Jason and Mike, and they have always been super helpfull. They are local, so I had them do my installation. Sorry I don't have their number here, but you can get if off one of their adds in the magazines.

Adjustment (don't call it jetting, because there are no jets to change) is simple. There are different size needles, which you use to set the mixture at 1/3 to full open throttle. Below 1/3 throtle, just adjust the needle height (you can do it out on the trail while you are riding).

Good Luck!

 

what happens when u only have one needle

 

Ah, I did have the phone number. It is 909-654-6677, ex2. Also, the pump shot is adjustable (the skrew on the side). See the article http://www.off-road.com/atv/projects...wiksilver.html There is another (better I think) article out there, but I can't find it right now.

 

There is a number stamped on the needle. Call the tech guys, and they can tell you if it is the right one. If it is the standard one, it works for engines that are not highly moded.

 

what is the pump shot???

 

This is a "pumper" carb (the stock carb is a pumper also). When you hit the accelerator, there is a "shot" of fuel into the carb. This improves low end response, and eliminates the hesitation you get if you just rely on air flow alone to suck fuel up from the float bowl. Of all the things to adjust on a carb, leave this one until last.

Has this carb been on a bike?? If it has, all the settings are probably different from stock. Call the tech guys, and they can tell you how to get it back to the stock settings. Then install it, and fine tune it according to its performance out on the trail.

 

THIS MAY HELP.

 

Mike-Thanks, that was the other article that I couldn't find!!

 

no this has only been on my bike. i bought it new and had someone else put it on and now he is nowhere to be found. i have a full procurcit T4 exaust, ported head, bored 20 over. i had a race cam and high compresion piston and all the other stuff but some how got sand in the motor(somehow it dint get the carb.) and had to get all new stuff and didnt get the piston and cam cause i had intentions on selling it at the time. so i really dont know alot about the carb cause the sand got in there on my second ride with it.

how do i ajust the stiffness of the throttle.
