Awesome, that's exactly what I needed. Thanks much!

Well, I finally got back to this tiller last night. I pulled the head off and sure enough the exhaust valve was stuck open. Sprayed it with some WD40 and spun the engine to cycle it for a little while and got it freed up so that it is now cycling on its own when I spin the engine. The head gasket actually looks really good too so I think I'm going to be able to re-use it (at least for now). When I put the head back on, I know there is a certain torque to set the bolts to, and I think there's a specific order to torque them in. Does anyone know what the order and torque are?

Thanks again for all of the help so far!

always torque from the center to the out side or in a star shape and torque is about 200 in. lbs

I would not take them up to 200lbs.in B&S manual says 140lbs.in, and like I said I would be careful at that..!

Ok finally getting back to this project. Is it 140 ft-lbs or 140 in-lbs?

That's what I thought, but being new to small engine repair, and given the first time he told me he said ft-lbs, I just wanted to confirm. After I posted the question here, I did a little bit more digging and confirmed that it was 140 in-lbs, or about 12 ft-lbs.

Just to kind of wrap this thread up (at least for now), after I torqued the bolts down I sprayed some starting fluid in the cylinder, and pulled it and it popped right over. So I siphoned the old gas out of the tank, put a little new gas in (treated with seafoam), gave it another squirt of starting fluid and it fired right up! After I let it run for a few minutes, I walked it back to the shed where it will rest until this fall when I'm ready to till my dead vegetable plants in to break down over the winter. I did notice that after a few minutes of 'use' (i.e. throttling up and down, going in and out of gear, etc to see how everything worked) it seemed to stop responding to throttle adjustments so I'm thinking that I might either need a new throttle cable, or else something might've come loose/off. I also noticed that it didn't seem to run nearly as well after I put the air cleaner on, so I'm thinking that that may be clogged as well, which might have been causing it to not respond to the throttle adjustments (if it isn't getting enough air, it makes sense to me that it wouldn't be able to rev up, I could be wrong). so I'll still have a couple of minor things to tinker with in the fall, but at least I got it running and saved this 'tiller's life!

Thanks a ton for all of the help guys!
