Hi all. I'm new here. A couple of years ago our lawn tractor rolled down a hill and had an unfortunate meeting with the back of our concrete garage. It started sputtering gas and the engine was sputtering too. I'm tired of paying someone to cut this grass, so I'm getting it fixed one way or another. It's a Murry tractor with a Tecumseh engine model OHV175-204803A. I had DH show me the damage, and after looking at the manual for the engine on-line (thank you MTF) I think that the carburetor is the problem. I was thinking that once I knew what the problem was, I could call some local repair shops (I have three recommendations) and see if I could get an estimate before bringing it in order to prevent sticker shock (or being ripped off.) BUT, now that I can see what it is, I'm wondering if I can possibly fix this myself? Just some background about me: I'm pretty handy (for a girl) when it comes to the house, BUT, I know nothing about engines. I don't mind taking things apart and seeing what is broken, but I am *very* nervous around engines and motors because I have absolutely no background knowledge, and would not have any clue where to begin troubleshooting. But then again, the problem with fixing most things is diagnosing the problem, and I already think it's the carburetor, so I'm halfway there. But I don't even know how the carburetor works? It may even be as simple as that little silver-colored bowl clip at the bottom. So I'm looking for opinions. Is this something that someone like myself could handle, or should I just take it in? It's also going to need a tune-up, which I don't plan on doing. And when the accident occurred, the brackets that hold the hood in place bent, so the hood is now crooked (possibly rubbing on the carb.) I think I'm gonna take it apart and try to bend the brackets back before splurging for new ones. And one other thing, the battery appears to be dead, no surprise since it's been sitting in the back of the garage for 2 yrs. DH says that unlike a car battery, it can't be charged. I find that hard to believe??
