OUTFXD Posted May 16, 2022 Report Share Posted May 16, 2022 Cleaning up the head trying to solve the leaking spark plug issue and I decided to check the spark plugs. Plugs 1 2 5 & 6 showed a some black soot but the insulator was dusted with grey ash. As I recall this is normal. Quote Link to comment Share on other sites More sharing options...
OUTFXD Posted May 16, 2022 Author Report Share Posted May 16, 2022 plugs 3 & 4 showed the same black soot around the edges, but the insulator showed some TAN ash. I dont remember seeing that before. Could someone with more experience (and a better memory) tell me if this is normal? Quote Link to comment Share on other sites More sharing options...
Sniper Posted May 16, 2022 Report Share Posted May 16, 2022 Tan is normal, it's the additive package in the gasoline, IIRC. Looks like your timing is good. 1 1 Quote Link to comment Share on other sites More sharing options...

I would suggest that you get another set of the same just to have as spares. If they are a regular plug then set the gap at 25. A friend of mine is running Autolite 295 sparkplugs and has found then at his local walmart. They cost around $1.85 each. They have the chrome base and are a replacement for the Champion J8. Whole lot cheaper than getting them off the internet. Just some thought on sparkplugs. Rich Hartung desoto1939@aol.com Quote Link to comment Share on other sites More sharing options...
OUTFXD Posted May 17, 2022 Author Report Share Posted May 17, 2022 I am running Champion J11Cs Just what was recommended by the local parts hause so I could get some fresh plugs in her. Quote Link to comment Share on other sites More sharing options...
keithb7 Posted May 17, 2022 Report Share Posted May 17, 2022 For comparison interest if wanted. Last week I took these out of my recently rebuilt 237 engine. 2 1 Quote Link to comment Share on other sites More sharing options...

maok Posted May 17, 2022 Report Share Posted May 17, 2022 You're looking for a nice light brown/coffee latte colour on the porcelain, electrode and ground strap. 1 Quote Link to comment Share on other sites More sharing options...
OUTFXD Posted May 17, 2022 Author Report Share Posted May 17, 2022 Thanks! Mine do have a little black soot around the edges (from running rich) I am currently rebuilding the carb and hope that clears it up! Quote Link to comment Share on other sites More sharing options...
Bryan Posted May 17, 2022 Report Share Posted May 17, 2022 If you're running gas with ethanol the porcelain won't color. If you found some "real" gas it will. Quote Link to comment Share on other sites More sharing options...
