So I am a newer blaster owner and my blaster has gotten harder and harder to start when cold. I was told to check my compression and it was around 95 PSI. I haven't torn it apart yet, but when inspecting the outside of the cylinder and case where they meet on the front end about the exhaust hole is a build up of oil and I was wondering if that would make enough of a difference to make me lose compression. Sorry if I seem like a noob with this, but I am.... Any insight would be appreciated. Thanks Guys!
