Old Sears Suburban SS12

Check to see if the flywheel key is intact

Yep, flywheel key is intact. I've had the flywheel off 3 or 4 times. I've had the magneto off and found a broken wire. That is why I originally wasn't getting spark.

Still continuing to mess with this when I have time. I've done a clean and install new gaskets and such in the carb. Still no start though. In playing around with this, you can feel suction on the carb as it is trying to suck air in. You can also feel air coming out of the exhaust as it turns over. Since I've been messing with this, now whenever I turn the fuel on and turn the engine over fuel comes out of a hole in the fuel pump. I've order a rebuild kit for the fuel pump. It should be here sometime this week.

Do you happen to no what year your Suburban tractor is. also, what kind of engine is in it... does it have a PTO.

Mine is about a '72 or '73. It has the 12 HP Tecumseh. I haven't messed with it in a while, but with starting fluid I will get occasional "fires" but sounds like the timing is off. I haven't pulled the flywheel off yet to get a new woodruff key.

It could be a blown head gasket too

Well guys, Saturday was a great day in the life of this project. It had gotten shoved to the side and I hadn't spent any time on it since this thread. I was moving out of the garage yesterday to a recently acquired shed. My son and a friend of his were there and they were helping. They wanted to hear what it was doing. So we started messing around with it. Low and behold, we were all thinking timing again - sound familiar? As I started to pull the flywheel off, the woodruff key fell out before the flywheel was even loose. So we proceed to pull it off and put it back together. I walked away to meet with someone that was there to pick up a goat. They tried starting it again and spraying it with starting fluid. The **** thing actually tried to start and actually did run for a few seconds. They went to the gas station and bought some gas and we put it in. It actually started and ran. We put the drive belt on it and it moved under its own power for the first time since 2002!!! Now, we couldn't let it run long as fuel was pouring out of the bottom of the carb. I jumped on ebay and actually happened to find a new carb for it. It is ordered and we will see when it show up. I also ordered a new fuel shut off valve for it....trying to keep it looking original. I will go to town and get fuel line, a battery, and a new drive and generator belt for it so we can actually get it running decent. I will also change the oil in it. Once I know it is running good, I will start the restoration process of it. Keagan's buddy actually went to trade school for autobody. I will have him lay the paint down on it probably with an automotive quality paint with clear coat. I don't plan on this being a worker any longer, but able to if wanted to be, but I want to be able to take it to the fair and display it and such.

Looks like Scotty was on the right track 8 years ago
