Hello Mark. Thank you for choosing Just Answer. My name is***** will be happy to assist you. If you partially close your choke, will your engine accelerate, without dying? This is a troubleshooting question.

No prblem occurs in any choke position

Thanks for your reply. You stated that you changed your fuel. How old is the fuel you are using now? Was your fuel filter clogged, prior to you cleaning it?

There is a possibility that if you make a small adjustment to your carburetor, this will resolve our problem. To make adjustments to your carburetor, you will need a special tool.

What special tool and if this doesnt work?
Expert:  Donald replied 1 year ago.

There is a special tool that is used for adjusting your carburetor. This tool is only made available to servicing dealers. Sometimes you can find them on eBay. I do feel that adjusting your carburetor will help. If not, you will likely need to clean your carburetor.

Will not be able to try this until tomorrow will have to get back with you then
Expert:  Donald replied 1 year ago.

No problem. The first link does not open for you. Try the second one. It shows how the tools look.

Your carburetor will have a (L) screw and a (H) screw. Open the (L) screw in small increments, counterclockwise, until your engine begins to accelerate smoothly.
