Hi everyone, can you help me with this issue. The engine (20HP Briggs,441577) runs smoothly only when the choke is pulled at least half way out. If the choke is pushed in, the engine will die. I have seen this issue on other engines so my question is.... what most likely is the problem? Thanks is advance for your suggestions.

Is this your carburetor?



I would ask if this is the carburetor you have first. since you did not provide a type number I can not be sure.
check the following:
Item #947 is getting 12 volts and moves freely. It is common for the solenoid to get clogged with old fuel.

Item#135 may be clogged or the gasket not seating properly


Item #131 should have no play in the body of the carburetor.

View your parts by type number at Arco Lawn Equipment | Home if you need.
