A few months ago a old friend of mine I've know for 40 years went and bought a Stihl saw at some dealer in my neighbor state of Maryland. He brought it to me to sharpen. Naturally I had to give him the riot act for buying elsewhere. He whimped out and said well I needed a saw right away and I was over in Maryland that day. I said well take her back to Maryland and get it sharpened. He goes but I'm here today, I go so whats your point. He gets whimpy not realizing I'm just pestering him. I warned him for buying elsewhere that it would haunt him. I sharpened his saw, we had a few laffs and away he went. Today came his haunting. He brings me the same saw complaining it won't start. I go thats whatcha get for buying it somewhere else. He says no, I was using it, refueled it and then it quit running. I go serves ya right. He goes well will you take a look at it. I go ya should take it back where ya bought it. He goes awwwwwwwwww man come on. I go what did I tell ya, told you it would come back to haunt you. He goes okokokokokok now take a look at it will ya, I go give me the dayumm thing. I open the fuel cap and the fuel is red. I go what is in this tank. He goes Stihl mix. I go oh no its not. He swears up and down it is. I get my handy jar and dump the fuel and give it a wiff. Hmmm its not even gas, its something else. I know what it is but I'm being sly. I spilled alittle on the table and tried lite it, it would not burn. He goes well what is it, I go its diesel fuel. He goes whatttttttttttttttt, no way. I go no way my azz, thats off road diesel in red tint. Re-fueled the saw with good mix and varoooom. He goes I must have got my cans mixed up. Now comes the good part. I said I'm telling all your brothers what you did and better yet do you remember me telling you this saw would haunt you, he goes yes, I go well ya beleive me now. He says I will never buy another saw from anyone else again, I go ya best not now give me $5.00 for a Wendy burger, he did, we laffed, all is good.. Topping that a buyer of mine brought in a little 180 complaining it won't run and groweling I just bought it 5 months ago. He's expecting warranty of course. I open the fuel cap, pure gas, I show him and he swears its mix. I go no way. He goes yes and growels I still have the can on the truck. Now its on. I say great, go get your can. He does. I dumped out my buddies diesel and pour his fuel in my jar, ut oh, pure gas. He says no way, I got the bottle of Stihl mix to prove it. I go great, get it. He does. I pour alittle in the fuel and it turns a nice pretty green. Now he's dumbfounded. I go you beleive me now. He's ticked. I pull the muffler off his 180 and its scored to hell, he's ticked even more. It gets better, he takes that saw back to the truck and brings in a 361 for me to sharpen. I opened the fuel cap for just a look see and sure enuff its got a 1/4 tank left of pure gas. I go well lookie here, another saw with pure gas. He isn't having any of it. I get my jar and dump in the fuel, pure gas plain as day. I go you want me to pour alittle of that mix oil in it to prove it to you AGAIN. He's like you SOB,LOLOLOL Never agru with a man that has a jar!!!!!
