In the last discussion about the hot engine from my 1937 212 a couple of members gave me the advise to take Champion C8 plugs.
I was recently in England and I tried to get them there. No way, in England they even do not import Champion at the moment.
All is NGK. Back in Holland I go to my parts schop and asked him to order 6 of this plugs.
He showed me on the computer that it was not possible for him to order them without a partnumber.
On the internet we were not abel to find that.
PLease, can someone help me on more information about the Champion C8 ?
For you in the USA it is as I understand at very common plug. In Europa you cannot get them anymore.
Is there also an old Champion number for the same plug . Perhaps I can find them on autojumbles.

    Hello,
    According to this site your car needs a J 8 (or J 7). Have a read, there is a lot of interesting stuff in there.
    I have not been able to find a C 8 mentioned anywhere.

  • You must mean Champion H-8. No such thing as C-8. The J-8's are what you need. Walt

    Sorry Rod and Walt , you are right!!! It is Champion J8. Just in my mind it is C8.
    In England people told me that the Champion is better for old engines than the NGK.
    I will try again to get them. Is there some information about the old code for the J8 ?
    About my heating problem : I' am now so far the car runs o.k. on patrol.
    With LPG after about 30 miles the coil is to hot and misfires again. Switching to patrol : the car runs perfect.
    LPG askes a little more energy for burning.
    I have had the advise to wind a sort of tape aroung the exhaust pipe.
    I found an address in Holland who can deliver the stuff.
    For me it stays a miracle that the coil never gives problems ( more than 7 years ) and now is much to hot. ( see : Hot engine ).That not only from the temperature under the bonnet but also from the ignition.
    Perhaps another place for the coil is possible. I think about under the dash inside the car.
    I inform you about the results.

    NGK plugs are very good, I always use them.

    Henk, I don't know if it is possible, but you most likely need a colder plug, set at a smaller gap. With the increased heat of the L.P.G. the voltage required to fire is much higher, so you need a colder plug, which may cure your problems. just a thought. I used to have Champion catalog, but can't find it. Generally, the lower the number the colder plug. perhaps a J6 if they are available. Otherwise, seeing you are already on 12 volts, why not go to an electronic ignition?

    FWIW, Hedley Bennett always mounts his coils inside car under dash and said he never has coil heat problem.

    OK guys, when I picked up my English built 36 Hudson (8 cyl), and got it running and got all the parts in the right place, I decided it was time to do a tuneup. I took four different types of plugs (H-11, C-4, J-11 and H-12 most were the J-11 plug) out of the car. The car ran fine--anyway, I put the right ones in with the proper gap. The car does not run any better but I feel better.. Kinda like my ducks are all in a row?

    If your car has been converted to 12 volts, did whoever did the job put a resistor in the line from the ign switch to the coil? If not, it could cause the symptoms you're describing pls the points won't last too long.
  • Check with a lawn mower service place. most still sell J8 champion plugs for small engines.
