Back in the 1970's I asked Champion for some samples of L61Y plugs for my 25ss engine. Unexpectidly they sent me a complete Racing Promo package that included a box of L61Y plugs, a pluge Tuning guide, stickers and sew on patches. I have scaned the tune up guide and it is available free to any that wants a pdf copy. Lots of usefull info. To large to post here 47 pages total at about 12 mb. Here is a sample:
Just leave your email in a PM and I will send it to you. Note sending to a phone email like gmail might have a problem with a 12 mb file being to large?
