What does it have for a choke? Is the choke flap in carburetor closing? Or is this just an enrichment valve? If no cable for choke, then the carburetor needs to be rebuilt!

just a enrichment valve

Expert:  Curtis B. replied 1 month ago.

Is the enrichment valve opening when the choke is puled? Or does the cable need to be adjusted?

Customer: replied 1 month ago.

It is opening

Expert:  Curtis B. replied 1 month ago.

Have you closed it down, then adjusted it just so it barely lifts off the seat?

Customer: replied 1 month ago.

Not quit sure what you mean sorry? Does it have to be fully seated for enrichment?

Expert:  Curtis B. replied 1 month ago.

No, it has to open the enrichment passage for enrichment.

Customer: replied 1 month ago.

ok so I should adjust for their to be a little slack in cable or should just have slight tension.

Expert:  Curtis B. replied 1 month ago.

I would start with slight slack in cable and then keep adding tension, until it gets better or worse! Same adjustment as Polaris uses.
