HELP!! SBC wont fire!
 

I have the motor all nice an in the boat. IT certainly has fuel and spark, but I just cant get it to light and run. It just back fires through the exhaust or carb. If I advance the timing it goes more through the carb, if I back it off I get neat flames out the pipes. I thought it may be the points so I converted the Mallory dist to electronic. I tripple checked the firing order, and timing, wtf is going on?

The last time I saw that , everything was perfect :eek: except the plug wires were in the cap backwards (wrong rotation) :rolleyes:.
Just a thought :crazy:

Re: HELP!! SBC wont fire!
 

180 out, or plug wires wrong.

No matter how hard I try I always screw that one up too.

Re: HELP!! SBC wont fire!
 

Oh crap. That is very possible. I've been working on Fords for a long time and wired it as if the rotor rotates clockwise. Is this correct?

Re: HELP!! SBC wont fire!
 

I think they should fire all those idiots at SBC.... Err oh... wait were talking engines.. sorry. It looks to me that you stabbed your distributer 180-deg off. BTW the roter does rotate clockwise on a SBC.

Yes,

The rotor rotates clockwise, but cylinder numbering is different than Ford. I did this once on a Ford 460, and spent 2 days trying to figure it out, til my buddys brother figured out how much of an idiot I was, wired it like a chevy!!!!

:eek: I can't believe I spelled rotor roter

Re: HELP!! SBC wont fire!
 

Firing order: 18436572

Re: HELP!! SBC wont fire!
 

You guys were right!! 180 out! I just swaped the wires around and it fired right up! She sounds great!!!! As soon as I get some exhaust hose in I will put it in the water! I'll keep everyone updated as this project finishes.
