One number #4 nylon washer from Ace Hardware measures out at exactly 2/3's the thickness of the stock washer...

Sounds to me like your needle has stuck.

The notches- that's what I mean.  Can the plate be installed wrong and if so what could effects be?  Are they for vacuum?

I did notice a tiny, tiny dimple on one side of the plate, but it doesn't seem to line up to anything, and seems too small to have any real effect on function.  
Puzzling?... I doubt it makes any difference to anything... Huh

There are two dimples in the plate on one side. the plate needs to be the right way up. I don't recall which is the right way offhand however. If the plate is upside down it wont align correctly with those holes in the bottom of the slide. I don't know what they are for but right side up the holes are both completely open. They're above half covered if you flip it over and bolt it down. That may be your issue.

Absolutely right. Right side up - holes open. Wrong side up - half closed. Just doesn't look right. I can't remember either where the dimple go Smiley

Yep, down.  

Here's a pic just before installing the plate.


Here it is with the plate correctly installed.


You know, I'm not so sure now if the plate can be installed incorrectly.  Kinds looks like the screw holes aren't quite placed in the same spot on each side.  


And, nearly everyone does this mod yet I don't recall anyone reporting back that they had problems and found they had installed the plate backwards somehow.  Whoever opens their carb up next can verify this for us.

Quit easy for the spring to slip off to one side when re-installing the diaphram cover - using a clean thin putty knife to hold down the spring while you put the cover in place might be helpful. Yes if it slips off the center of the plate it will prevent the slide from opening up and produce a moped

If the #4 washers are too big just put them on a long bolt held in place with a nut - put the bolt in a drill and turn them down to size against the garage floor - instant redneck lathe

Thanks for all the replies.  I guess I'll take the top off the carb and make sure the springs good.  I'm almost positive I installed the little plate correctly.

So the spring was jacked and I corrected it.  That took care of the moped thing but I'm still getting backfire on deceleration and shutdown.  Does that mean I should put in/take out another washer?

Open the air screw 1/2 turn.
In some cases that back fire on shut throttle is a feature ...  Smiley
Cool.

Grin An attitude I can sympathize with.  After my white spacer mod and new exhaust I now have hardly any pop on shutdown, more of a little burp/gurgle.  I do however have a real nice snap when I wind it a little and let off, or after rapid upshifts.  Not so much on just decel though.  As long as it's not running way rich or lean, I kinda like it!

Make sure the washers you used fit into the hole down in the slide.  If they don't , you'll lean out your mid-range preformance.  

And, make sure the washers are on the correct side of the needle and spring .   If the washers are on the wrong side you'll be real rich.... trust me on this one.....
