Ok i got a chance to go do a compression test!! I cleaned the area very well with a air line.. The redings were 1. 90 2. 90 3. 100 4. 102 5. 101, and six i could never get too!! Soo i sprayed them with deep creep, i also sprayed the inside of teh carbs with deep creep!!! How long should i let deep creep sit in them? I was hopeing to get the numbers up higher on the readings!!
