spark plugs ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I keep fouling out plugs on my K5 Blazer............It is work in progress and doesn't get ran much so I'm not sure why? Could it be bad gas? Is it because it never really gets ran but just idles? What kind of spark plugs should I get for it and what gap should they have? All help would be appreciated....I need to get it running again so I can get it out to where I store it for the winter. I need to get it out there by the 20th. Let me know if you need more info from me.

.45 gap. Is it not running now?

It won't start but ran in May when I brought it home from storage this Spring. I figured I'd buy some plugs and try and start it again. I tried to jump it today but it barely was turning over and not starting.

retard the timing a bit then try again, see if you have spark.

What plugs are you currently using?

Define 'just idles'. If your starting it periodically, let it run on high idle for 5-10 minutes, then, by hand (finger) drop down the choke linkage a setting (or two) so it isn't at a low idle, and let it run for a while longer. You want it to reach operating temp and stay there for a bit to get condensation out.
