I am looking at purchasing a 97 Trailblazer. The person selling the quad said it is hard to start. I am going to take a compression reading to make sure the top end is in good shape. What should the compression reading be? I'm thinking 150-190 but not sure. any info would help.

 

A good condition stock blazer should read about 120 pounds .

Rick - Thanks for the info. I was able to run by last night and check the compression. I was getting 125. Looks like a winner.

 

Hard to start could be something as easy as a new spark plug, jetting, not choking right......that is not a problem,,,,,we can help ya though it....

 

125 huh??? mine runs 129 wit a mill so it might be milled a stock head will run no more than 120 i thinkk
