My neighbor asked me if he could borrow my backpack blower the other day. Can't say no. He's seen me in the yard using it. Can't use the excuse "it's broken". He's a good guy. Well, he had it for 2 days. Used it on some other properties he owns. Stuff never comes back the same way it leaves. Shoulder straps were readjusted, and I could tell he dicked around with the carb adjustment. Plus it looked like he had straight gas in the tank after I told him to use a 50:1 mix. Anyone else run into this problem???
