hello everybody, I am new to the forum as of today. I am a full-time mechanic and I work on heavy equipment daily. So I understand the basics, I am having a frustrating issue with my snow blower. Last season it was very hard to start and eventually became a no start condition. Whenever i pull the cord it backfires out of the exhaust, even when using starting fluid it will not attempt to start, it just backfires from the exhaust. It is getting spark and obviously getting fuel viA starting fluid, I also replaced the carburetor last season with a brand new one. I have removed the flywheel to check the keyway. Everything looks great, I thought maybe I had a stuck valve so I pulled the jug cover off and both valves are closed and good. They will hold some WD 40 for a good half hour or more without leaking.head gasket also looks good.as of now I am completely stuck with this thing. I do not see anything wrong. It is a good old snow blower, very heavy duty all metal with tire chains, I hate to just trash it. Hopefully someone can help me out here thanks guys

Heh You and I are in the same boat with these one lungers. . . . We can rebuild a Cummins blind folded, but can't get or little motor to run. Go figure.
Anyway Welcome
Yeah weird one. I was thinking burned valve too. Did you take a compression test on it? Timing? Yup I just found out these old Tec's need timing.
Here's the link to the manual these fine people gave to me. http://www.mymowerparts.com/pdf/Tecu...NES-692509.pdf

Through the many years as a mechanic I started working for Chevrolets dealer on trucks when they first started coming out with the V8s gas engines up to diesels so I worked on them all. You will find that the basic running of a engine hasn't changed much through the years as when they first come out in the early 1900's. Fuel, ignition, compression, and timing. Just the newer equipment now has added a computer to make things run better. Seeing you are a full time mechanic as I was you have to see changes yearly and have just adjust to it. I was talking to a truck driver and he was telling me that his diesel was computerized so they have changed since I worked on them in the early 80's. I am sure that if you start working on these small engines that it becomes a enjoyable hobby which I have found now in my later years. Yes you will learn as you go and make some mistakes along the way which I sure had done. My problem is I added motorcycles to the list and found I love to ride them more then work on them... Love retirement
Hah! Listen to you. LOL I'm retired too
I'm not a full time Mech either. I was one of those people you people cussed out. An electrical engineer. I had a few strokes a couple of years back that took much of my scholastic and administrative faculties away. My mechanical skills started when I was a kid on a farm. I was fixing John Deere's at 13 years old. (I spread my share in those days too) My mechanical skills have been sharpened over the years because I am a car and truck nut. I spent loads of time at the dealer service dept learning too. Today I restore my own. Everything but steering boxes and interiors. They tell me I am above average mechanically. That;s why this little devil is so embarrassing.
They're usually on the fan shroud
That looks better :thumbsup:
