Hello. My name is Tan.

Remove the flame arrestor when engine is cold. What position is the choke plate? If it is open close it by adjusting the choke module. If it is closed how tightly closed is it? If to tight it can cause the engine to flood.

Now if adjustment ios good then turn key on and watch the choke does it start to open?

Customer: replied 2 months ago.
It remains closed completely while trying to start. It is definitely getting fuel because you can smell it after a few cranks. I pulled the wire going from the coil to distributor and there is spark. It just turns over and does not really seem like it is trying to start just turning over.

Ok open the choke plate. Loosen the 3 screws on the choke module and open the choke plate just a little. Once you have it set try starting the engine. If the choke plate is closed to long it will flood the engine. Once you get the engine started verify the choke is opening.
