Morning sickness
« on: August 11, 2007, 02:56:36 PM »
Sometimes (about half the time) when I first start up from dead cold, one or more cylinders do not fire.  So far they have gotten heat from adjacent cylinders (I presume that's what is happening) and start firing OK within 5-10 minutes. 
Once I pulled the spark plug of the dead cylinder (as evidenced by the cold e. pipe) and cleaned the oily gas mix off the electrodes, popped it back in and away it went.

Ideas?
Too rich at idle?
It is not consuming oil and has recently been overhauled ie 1000mi I think.

Is it always the same cyl's and are they on the same coil? It might be the coil soaking up heat and start working.

So far I can recall #1 and #3...so maybe you are right. 
a marginal coil. 
The spark appears hot when I hold it agin' the cylinder and crank it.

Yep, a set of DYNA coils changed all that for me.  ;)

Compression can easly change that, it will tell you if the wiring is intact and you have power but that is about it.
