Re: Autolite 75 plugs

[Schuyler Wrobel <sky62@xxxxxxxxxxxxx>]

hey rich, back in the days when I was driven around with that old  
tired oil burner
of an engine, I was replacing plugs all the time. I quickly learned  
that all these plugs needed
was a good cleaning and then they worked fine. sometimes my car  
wouldn't start, so I'd start pulling
plugs and clean them up, with a little wire brush tool I had, and the  
old Poly would fire right up.
that was a long time ago but I have saved sets of all 3 of those heat  
ranges also have some AC's
and a set of Bocsh Platinum plugs. the only time I tossed them was  
when the electrode looked
damaged beyond repair. those 75's were the normal heat range for the  
Poly if you can find an
Autolite plug with a lower # then 75 in the same size that would be  
going to a colder plug.
I have Champions in the half built Poly I am running right now. I  
think they are J12 YC or something
like that, I recall I was looking for 9's but can't remember if I  
ever found those. My Poly doesn't foul
plugs anymore so I haven't had to check them in a long time. last  
time I did check, they were all in the pink
so to speak- that pinkish or hazy orange cast to the electrode and  
that ceramic insulator area around it,
which indicates they are or the engine is burning good, from what I  
understand anyway.
