I have the same problem, with the plug on my savage 25, my LHS is useless, so I buy all parts from the internet, I am running 20% nitro, I went to tower hobbies.com and looked and glow plugs but none of them specify to be used in a savage. So which plug would you guys recommend for just general operation. I see they have xtra long reach plugs and different temps, what is a good all around plug for a savage 25??
