More PP455 Questions

[thomas72]

I have just replaced the top end on my 455, and would like to know if the blow back tube has a gasket or does the plastic tube make a good enough seal? What type of spark plug does it use? I have a champion CJ7Y in it, and would like to know if it should have a hotter or cooler firing plug as the plug is a lighter brown than what I am use too. It also has the standard air filter assembly, does the other filter assemble with the round tapered filter work any better, or is the standard flat filter work okay?

CJ7Y with gap at 0.025" recommended plug. Here is an IPL , page 9 shows tube and a gasket.

Thanks for the post. I had seen the same IPL earler, but the gasket looks like the one that goes infront of the carb.
