Re: [T3] Only Running on Two

<x-flowed>Hi,

Thanks for the ideas. I didn,t replace the points yet but I did clean and 
gap them last night. It seems to have good spark.
I just now changed the manifold pressure hose. No Luck.
I just now checked the voltage and it looks to be between 14 and 15 volts. 
My volt meter has the needle and the DC scale is small but it holds steady 
right at 15 volts.
The problem is only with the left 2 cylinders. Why those 2? It's got to be 
something incommon with with them.
Any other ideas?

Thanks again,
Randy
