Your problems could be caused by any number of issues, or a combination. You’ll need to find a local mechanic with carburetor experience to perform some hands-on, tools-on diagnosis.

Very difficult when first start in the morning and took more than 5 minutes to idle and sometime experience dieseling when shut off. The jetting is factory standard. What seems to be the problem. Thanks

First how do you adjust secondary throttle plate with screw stop? I am down to a 120 p
main 170 air 50 idle jets and still runs rich?

The 32/36 is intended for an engine about half the size of your 250. Your engine is so large that the butterfly must be open quite a bit just to get enough air to idle. Opening the butterfly so far exposes the progression holes to manifold vacuum, which usually means a very rich idle and a lean stumble when you open the throttle.

You might try drilling a hole in the primary butterfly to allow airflow into the engine without opening the butterfly so far. Start with a small hole, maybe 1/16″ or 1.5mm, and go up from there. Take a look at some of the books mentioned in other comments to see where the butterfly should be in the idle position.

The ideal solution is to get rid of the toy carburetor and go back to one designed for a large engine.
