the choke shaft into position in the lower body casting. Place the choke
plate on the flat portion of the choke shaft so that the poppet valve spring
is at the bottom of the air inlet, pointing inward. Install two new choke
plate screws snugly but do not tighten. Check for binding by turning the
choke shaft. If the choke shaft turns freely, tighten the two choke plate
screws and stake the tips to prevent loosening, using Manzel Tool No. 9586.
If binding is noticed, tap the casting with a fiber mallet and recheck.
