I purchased an Echo PB9010T two days ago to use for my small mowing business. I have never used equipment with a 2 stroke engine, nor did I fully understand how to properly operate said equipment. Long story short, I thought I could run it with straight gas. 5 minutes into blowing it craps out on me. So far I've drained the gas, added new gas with the proper mixture of oil, changed the spark plug, checked the air filter, and that's as far as I know to troubleshoot. I definitely damaged something internally for it not to be starting. Should I take it as a loss or is there something I could do to salvage it? Thank you in advance for all the help!
