Looks like Champion is no longer supporting this type of line. We are losing drag strips the hobby is getting more and more expensive. I need to win the lottery really badly!
I was running Autolite 65 and just installed the 64. I just was ready to cut over to Champions. But Champions are confusing me. At least I can read the Autolites they are available everywhere and the heat range is linear.
C6C and C6YC are not included on Champions site. Only the C61YC=794
Without the other plugs it doesn’t seem like I can use just the 61 if I can’t go up and down the heat range. I need to be able to tune. I am not familiar with Champions race line at all.
Champions web page sucks. No product...
