917 295350 Craftsman Rototiller Fuel Supply

Thank you so much for the great information! The engine numbers are in a photo, as well as some longer views. The videos you sent are more than excellent, and from Bald Eagle 242's commentary and additional video, I think I have found the actual problem keeping this engine from starting and running. When I sprayed in some ether, it only popped at the intake. Didn't try to fire. I now realize it's likely that the intake valve is stuck open. I suppose we will need a head gasket. Again, thank you!

Not so much that the intake valve sticks open. More likely the valve face and seat are worn which basically, the valve clearance closes and get held open.

I'm working on a rototiller a friend got at auction. It ran fine at first, but quit,and can't be restarted. It pops out of the carburetor, but won't really fire. We suspect fuel inlet needs cleaning, but the carburetor is mounted directly to the top of the tank. I haven't seen that design. Anything I should know before I start into it?

On an additional note:

You are dealing with more than just a carburetor problem. Possibly it has a stuck or very worn valve valve from year of sitting.

The popping back through the intake on a flat head engine is normally associated with a lack of proper valve lash issue where the valve face has worn into the seat from years of running.

My advice is to search around for a small engine DIY person that knows what you have and how to deal with it. Amazon or eBay cannot fix this, only experience and the right tools will revive this.

Read post #14.
Best to not start taking things apart until you have done further testing or as post 14 suggests.

Can you do a compression test with a gauge?

If no compression gauge try this to get an idea if it has any compression before you remove the head.
This is how to get an idea if it has any compression without using a gauge.
