With the ambient temperature at 68 degrees F. (65~70 is close enough); depress the throttle to wide open and release (this releases the choke lockout); with one hand hold the throttle about half open; with the other hand slowly rotate the choke cap until the choke butterfly starts to close, and continue to rotate until the choke butterfly just touches closed; release the throttle, and tighten the choke cap retainer screws. This procedure will adjust the choke to standard setting.
It is possible that depressing the throttle to wide open will close the choke valve.
Jon. Good carburetion is fuelish hot airThe most expensive carburetor is the wrong one you attempt to modify. If you truly believe "one size fits all," try walking a mile in your spouse's shoes!The Carburetor Shop | | |
