Hi Guys
Just finished cleaning the carb and tried tuning the engine. I used a vacuum gauge to set the idle. The maximum vacuum I was able to achieve was 15.5 in. Hg. The book says I should get between 17-21. Should this low number be expected at Calgary's elevation of 3500' above sea level, or do I need to do more work?

Thanks for the help.

Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.
