"We need a better explanation

"We need a better explanation of what the engine is doing John. Id there compression on both cylinders, and if so what are the readings. Do you have spark on the other cylinder that will jump a 7/16" gap with the spark plugs removed?

Are you not getting spark to either cylinder? Describe the problem as good as possible."
 
it has compression but have no

it has compression but have not took a reading. the problem is neither plug is firing but the coil ohms good. im not sure if the power pack is bad or or if its not getting power or the signal to send fire to the coil and dont know how to check it.
 
Attempting to trouble shoot el

Attempting to trouble shoot electrical problems without a manual is very frustrating. Either buy a service manual for your engine (e-bay or elsewhere on line) or check your local library.
