Re: Any help for a new guy?
Backfire out the exhaust and black plugs sounds like it is too rich and fouling the plugs. Of course, as some suggested, if the spark is not always as strong as your test showed, you could get the same results. When in doubt, replace the condenser.
When it won't start, pull a plug to see if it is wet. Do you smell raw gas under the hood or out the exhaust pipe?
