Starts right up and runs...dies when chocke is opened past half way

the carburetor needs to be cleaned or a new needle and seat installed. engines will start but may only run on choke, are starving for fuel. this means that the carburetor has a problem. usually a good cleaning and maybe a needle and seat will cure this problem.

The main jet of the carburetor is likely blocked by a piece of debris. You are going to need to remove the carburetor and clean it thoroughly. If it is one that has the carburetor mounted on the fuel tank, replace the diaphram while you are at it.

I hope this was helpful.

For mtd 3hp 2cycle motor only stays running when pushing prime repeatedly on full chock 5 sec

This is usually a symptom of blocked or partially obstructed metering passages in the carburetor. Carburetor should be removed and metering passages cleaned to restore fuel flow through the carburetor.

Poulan pro 42cc starts when choked,take off choke runs almost 1 minute and dies.chock and restart same thing. will not stay running even when throttled.

Check the fuel filter, air cleaner, and muffler for plugging. Inspect the fuel lines for decay or other damage. If no help, remove the carburetor, disassemble and clean the interior with spray carburetor cleaner. Check the condition of the diaphragm in the lower chamber--it should be flexible with no holes or cracks. Also check the small needle valve that the diaphragm controls. Check the crankcase impulse passage behind the carburetor for gasket failure or other damage. This passage pulse-pumps additional fuel into the carburetor as it runs. Hope this helps!

Is your air filter dirty? If so replace it. If it is still doing the same thing try this:

Turn off the fuel valve, or drain the gas tank, then place a rag under the bowl to catch the gas that will run out (the bowl is under the carburetor). Loosen the "nut" that holds the bowl on, and after the gas has stopped draining remove the nut and bowl. Blow out with compressed air, if available. Put the bowl back on and try to start it. If it still will not run off choke, the carburetor probably needs a good soaking or to be replaced.
