I have an old Echo blower that was running ok and then put into reserve and not started for about a year. I just need a blower that can be used once a week or so on a property I have elsewhere. It is not cranking now and I'd welcome any help I can get diagnosing the problem. It's 10 years old but was used only half the time by myself so the hours aren't what they might be on a heavily used unit. 1. It puts out a spark that seems healthy. I also replaced and regapped the plug to spec. 2. Air cleaner is a newer one. 3. The carb was replaced a few years back but has minimal hours on it since it was just a backup unit. It ran pretty good after replacement, so I assume its settings are ok. 4. New fuel strainer installed. 5. It will run for a few seconds after I spray a little fuel in the cylinder. That makes me think it is a fuel supply problem. The rubber tubing is mostly original and this unit is 10 years old. Could it be a vaccum problem getting fuel up to the engine? Do I need to remove and visually inspect them all or is there a quicker way? 6. I have a compression tester but don't know what spec to look for. Any ideas?
