dynojet kit questions?

anyone know what the purpose of the 2 little washers that go on above the clip that snaps on the needle?and then the plastic housing goes on that and is held down by the springs.what would change by removing the washers?

Removing the washers would result in a leaner setting...the washers fine tune your clip settings...needle "in" is richer and needle "out" is leaner...I think...yea pretty sure thats it...

The plastic piece keeps it all together once it is installed...

the washers go onto the top of the clip on the needles and has no affect on the height of the needle.doesnt the clip do that?

Without them on top the needle can move around some causing it to run richer.

They just go there

Actually they work together...the washers are 20,000ths each and if they are on top they will push the needles "into" the carb and thus effect your metering...so you can fine tune your clip settings...

well i am using one washer on both instead of 2 becuse i lost one of them.anyways there is no slack in the needles when installed.you guys are saying that the 2 washers are for taking up slack in between the needle clip and the plastic peice so there should be no slack.

consider them 1/4 clip adjustments. if you need to be in between clips 1 and 2 or 2 and 3.

I never said that...I said they will "push" the needle into the opening 20,000ths further...thus effecting your metering...

The spring keeps the tension or pressure on the spring seat (plastic piece)...now under that is the needles that sits tight against the spring seat based on where your "clip" is...and how far the needle projects into the vacuum piston...so logically if you put a washer or 2 between the clip and the plastic seat base then the needle will project into your vacuum piston 20 to 40,000ths more...thus changing the amount of fuel your carb is going to have to meter...it matters...

Don't feel bad...I have one on one carb and two on the other because I lost one two...somewhere?. I had wondered this before too....it's tricky to even get the thing put together. Anyways, I'm glad it was asked. Good question.

SJ is exactly right, look at this way... there is no sense in adjusting clip position, if you don't have the washers in there, wish I was technical enough to explain....(I ain't) Your needle clip adjustment would be somewhat senseless without the washers, [BECAUSE] this is going to effect your "MID-THROTTLE" mostly. It is also going to affect the fluent shift from mid throttle to just flooring it (and that is why they (washers) are there), you will have bog downs and skipping in mid throttle to hauling ass, my only proof is that...I've done this a thousand times, and I know (I did it stock with muzzy's and 840 with muzzy's) , really... I ain't kidding...I have had these carbs off well over 100 times...that's cause I'm ignorant.....but so be it.....if you can't accept that....then I don't know what to tell you. The people telling you this are from experience, not from an engineering perspective.......from experience, they know.
