Ya, for sure I'll be getting ahold of S&S Mon., I'd sleep better if I could get her going tho. It's disappointing, I spent all winter going thru it top to bottom to make it a good dependable sickle for the next few years. I'm bummed

 

You need 3 things for engine to run..Fuel, Air & Spark.. you said it has \Spark and you can rule out air unless your air cleaner is totally plugged.... only thing left is Fuel.. Simple. You have a Fuel delivery problem...

 

Well, I wish it was simple. Not to say I couldn't be wrong , but when I let it sit for awhile then try and start it I get a backfire, then cycle the ignition switch and try again and it just turns over and doesn't fire. I pull a plug and it's wet, that tells me it's getting fuel.
Fuel, Air, Spark ....what about timing? Doesn't the ECM control timing?

 

Well.. you left out the plug was wet in your initial post. so yes. If you have fuel, air and sp[ark and it still doesnt run.. then you could have a timing issue.. sounds like something moved somewhere for it to stop running...

 

At the point you are at now, I would just wait until tomorrow and call S&S. You have so much into the motor and if you do something wrong, it will just cost you more money. Get as much info from them as you can EG: what do I test, what should voltage be, and where etc. etc. Followed up with well if that checks out OK, then what? S&S is a well known company, I cannot imagine them leaving you on your own for this one. If you have any trouble, casually mention this forum and how you are keeping us up to date on what they do for you, sometimes that helps.

 

make sure you have compression in both cylinders. without that, all the gas and fire in the world wont do any good

 

BINGO! S&S said they had a bad batch of Valve Springs
Lucky me

 

Aways the most obvious stuff that bites you in the shorts. So are they going to fix it for you? And - when??

 

Cool, hope that is it and you have a speedy recovery!!!!!!

 

They said to take it in to an authorized S&S dealer and get it fixed and the would pay up. My problem with that is, I thought I was buying a good dependable motor I could put in myself and not have anyone else monkeying around with my ride. Now I'm supposed to trust someone in my motor when I didn't even want somebody else messing around outside the motor.
