Rebuilt? Did you set the float level?

Yes, I will check that again though.

Plan to replace all the ignition bits I listed, then pull the top off and spray out the jets/check float level

Also, check that the seat is tight. Make sure the sealing gasket is there, or it can leak back.

The one the needle valve goes into. Basically, your problem appears to be that the float bowl empties, and it takes a large open throttle to refill it, and then start sucking fuel. That delay is making it idle like crap and hesitate. You need to figure out why the float bowl is not filling up and staying full.

Look down the carb with the engine off and go WOT fast and see if the accelerator pump is working. If you try that while it's running watch your eyebrows

It is working. If i go wide open or pump the throttle it squirts in.

Man, it could be so many things... Be careful of fire. If it flares up out of the carb, hit the starter and try to suck it in. Good luck on it.

Its a 2100 so yes you can. BUT BE REALLY ******* CAREFUL. I don't want to have to re-learn what you look like.

Funny this... I was going to utag rleete and hornetball earlier but I was on my phone. I figured one of you two guys would know how these things work

Lol @ Constant throttle rpm oscillation vid, no one ever accused those fans of not moving enough air

****** still is being weird.

Sometimes it runs fine, then kinda slows down, starts missing, slowly dies. I tried basically every position for the idle mixture screws.

I'm thinking I might not have cleaned it out well enough.

Well I'm pissed, probably taking the day off work tomorrow to try and get it running.

In other news I'm going to do a small announcement in my thread, and later were going to do a big announcement with a group buy. Some of you may have noticed the links in mine and seans signatures, but SADFab is official. Website and everything.

www.SADFab.com

The website is very basic right now, as its just a copy of my personal site, slightly edited. But its a place to show off our "products" which is really just us doing group buys for our open source projects.

Thats right, everything we do/design is going to be open source, and we will supply all dimensions, CAD drawings, schematics, wiring etc. Basically if you have the tools, you can reproduce everything we do.

See here: www.SADFab.com/opensource.html

Our goal isn't to make a profit, but to share information, and cheap products with the community. When we do group buys we will calculate in a labor cost, and a small administrative cost to cover websites, stickers, etc.

Our first product, and the one that really started this idea is delrin bushings. More information will come in the official announcement but expect an entire delrin bushing conversion at a price that beats everything else available.

Give it a bump of carb spray when it's idling like ****. If it comes alive, fuel issue not ignition. Sounds like lean spitting starving for fuel to me. Might be sucking the bowls dry/bad pump. Is it mechanical pump or electric? If it revs/runs under power it's probably not the pump. A weak mechanical pump might not work at low revs, seen that before on a 302 long time ago.

Also if you have a vacuum gauge, what's it show? A vacuum leak is most likely problem if it's not a pump and you've already rebuilt the carb.
