  1. I have 3.5Briggs and Stratton lawn mower engine that I cannot get started. It has run in the recent past. I recently drained the gas, replaced the plug and air filter and cleaned the carb. My question is what should I set the idle speed adjustment and idle mixture screws at for the initial setting. I am getting spark and it seems like it wants to run. I just cant get it to. Any help is greatly appreciated.
