Reading back, you should have a Walbro LHM carb on there, you can still get rebuild kits.

 

I wonder about the previous rebuild and what might have gotten messed up.

 

There are 3 separate adjustment screws on this carb, the needle on the bowl is for higher end and the other one on the side is for the actual air/fuel ratio mix, then the other is for low idle rpm throttle stop.

I would screw both the bowl and the side screw out to 1 1/2 then go from there.

 

My carb is very touchy due to it needing throttle shaft bushings.

SO here are a few pictures, I think the engine is from a GT16(because it's orange), Body ST16, Hood SS12

Carb was rebuilt first, then a gasket set for the head and exhaust leaks, then new head. Seems like I need a starter now. And maybe a new carb.

The third photo shows a spring that was hanging no one knew what to do with it. Any and all help it welcome. I only have a few weeks to get going.

That's definitely not the stock motor, not even sure that's an OH160 that came in a sears. The only ones they painted orange was in the older suburban 10& 12's late 60's/early 70's.

That carb is set up a lot different than my '77 16, does it even have a choke lever/butterfly? if not, that coule be your hard start issue. Mine has the adjustment screw on the side, I see yours is on the top, wondering if this is a newer motor or carb?

 

how did you determine this was a 16 hp? If you look on the flywheel side on the lower oil pan, there should be a number stamped, that will determine the HP of the motor. Inside the blue circle in pic below, just on the side, not the front

I'm wondering what it came off of, that's not a Sears throttle setup on the flywheel or the choke assembly...or the lack of.

Maybe it came off a welder or generator that was idle or WTO?

Do you mean the carb? or the whole orange thing (engine) I think there is some old beige/yellow paint under the layers of orange.

Those pics help. I didn't see the choke so was confused.

 

Are you sure the cables are in correct positions? My throttle cable comes up from under the flywheel and connects to governor ( yours connects to choke) and choke comes up over the top. Obviously yours is changed, but just something to double check.

 

I don't know. My guess is that little extra springs was added due to a governor issue.

I'm also wondering if the throttle cable should be attached down lower on the governor arm where the paint is chipped away.

So far the starter was missing a bolt so was out of place and grinding. Nathan has it going now. Adjusted the carb and is working on throttle.

YAY!

Glad to hear its getting better.
On your machine, which moves the butterfly closest to the engine (the one on top?)

Yes?!
Seems better but since I have no experience with how it should run, gun shy. Seems really hot, and would love to know how to find the right high-n-lows...Hate to say it fellas but sometimes it takes a lady standing over a the fellas saying....these other guys say to try this...as opposed to the...we worked on it for hours and it...

so Really THANKS for all the
input, it made the difference! It runs! and a few hours at the shop, reading your inputs aloud.

The throttle moves the butterfly closest to the engine, if I understand the question correctly. Nathan made some adjustments to the carb and she lives to see another day! I asked him if I could drive it home and he said he thought it was a bad idea, trailer it home and drive it around the neighbor hood for a while. Easier said than done. Still thinking it could use a lawnmower man's fine tuning but we shall see. Nathan burned his arm pretty bad on the muffler. Now it's time to start on the mini-float!

Hope Nathan's arm is OK.
Glad it's running. Time to run it a little and then change the oil. Good chance it got watered down with excess gas and its a good idea to change it anyways. After that I would find an excuse to at least drive it around the block.

During the parade, running it at a mid to lower RPM will help with the noise and heat, also reduce the chance of an issue mid stream.
