Small Engine Repair

I have been looking for someone to repair my little tiller for some time. So long, that I wasn't even able to use it last year. The only problem was the repair shops wanted to charge around $60 an hour. If a small engine mechanic can get $60 and hour for his specialty, than I should be able to get $60 an hour for putting a new zipper in a pair of jeans. After all, sewing is my specialty. I know, realistically that would never happen, but some jeans are sold for as much or more than my tiller was. I didn't say "worth as much", but "sold for as much".
I finally decided that it was doing me no good sitting there. I had to decide if I was going to pay to have it fixed or try to tackle it myself. I opted to attempt to fix it myself. I pushed on the primer and no gas would pump into the bulb. Now I know that it is not getting gas. So I checked the gas lines and one crumbles in my hand. I love Google and resort to looking online. I find a weed eater that is similar to my tiller. I study how to change the gas lines. I remove the cover, even though I am not sure what it is covering. I then take out a couple of more screws to allow me to remove the gas tank. I head to the local parts store and picked up a foot of gas line for $1.05. It was just enough to run the 3 different lines. I figured out how to put them on and attempt to start it. No luck, so the gas lines must be in the wrong position. I attempt to connect them again. Wow, one, two, three pulls of the rope and my little tiller is running. I am so happy and proud of my accomplishment. I worked up my small raised beds and planted my tomatoes. Now, I wonder if I could fix the big ancient tiller, sitting unattended and neglected? I do have the courage now that it takes to attempt it.
