Thanks for all the info... I been running the stock china plug and want to upgrade. My motor seems to run fairly cool, so I think I'll go with the B6. And thanks for the cross-reference number... the help at O'Reilly's is not very savvy when it comes to parts that they can't look up on the screen.Yer right, The B6HS is the middle of B5 and B7. So if the B5 OR B7 is OK, why not the B6? ( Not too hot, Not too cold, It's just right.) These engines generally run a little cooler than most 2 strokes so a little hotter plug is fine. I don't know why you would want to run a cooler plug though. I don't know it all so if you can explain it perhaps I'll learn something new.
Big Red.
