Roper starting issues

I acquired a Roper two stage snow blower that doesn't currently start. It sat for an unknown number of years. I haven't been able to find any manual, or parts list in my searches. If you have one, or know where I can find one, please let me know. I drained the fuel and oil, replaced the fuel lines, checked for spark, and cleaned the carb. I have never rebuilt a carburetor before, and I'm not sure I have things adjusted correctly to start. It has fresh gas and oil. Any tips would be appreciated. Thank you.

Welcome to SBF Mr.Smith. The stamped 737 number on your carb body indicates it is Tecumseh carb number 632113. Looks like a 5 hp motor.

Remove the spark plug and squirt a little gas into the cylinder, install plug and see if the engine tries to start. If it does, the carb may be dirty or worse. If it doesn't try to start, you may have ignition or possibly valve problems.

Experience is something you don't get until just after you need it.

Thanks! I’ll see if that works.

My engine is only a 4hp. The link for the carb is not the right part, so I will do some more checking there. I am definitely having a carburetor issue though. It does not seem like fuel is making it from the carb to the motor. I sprayed some carb cleaner into the intake and it fired right up for a second.

I would suggest trying to clean the carb , but if it were mine, I'd just replace it with one from E-bay...

What is different about the ebay carb and yours? If yours is non adjustable, this is an improvement.

Keep in mind I am not an expert by any stretch of the imagination. On the carb in the link you provided it looks like there is the main jet and also an adjustment screw on the bowl. On the carb I have, there is just the main jet on the bowl and the adjustment screw is on the side. The manual you provided has been helpful. I have identified the type of engine, it is definitely a Tecumseh, I pulled the carburetor off and need to clean it again.
