The LHS... And a whole heap of online threads... Suggest running a cold plug for my savage XL. I'm runING a hot plug at the moment, it's running really nicely . I tried to put a cold plug in but had a dog of a time getting it to run nicely. Hoping someone more experienced than me can suggest what I need to do to transition from a hot to cold plug. I understand the basic principles, that a cold plug needs to run leaner, but how much? I'm very worried about going too lean. Are we talking a quarter turn leaner? Or a significant change? Will there be a noticeably lower amount less smoke running leaner setting on a cold plug?

If it is running well on the hotter plug...please refer to the following rule....

If it ain't broke.....don't screw with it :)

The rules are not set in stone, some engines don't want to play by the rules, and this is a perfect example of that....if you are happy with the current set up and it works, throw the rule book out the window and just enjoy some good runs
