Thanks for the reply Mowersnob. I’d found this previously but I can’t find an area that addresses the concerns I have.
“I’m interested in the spark plug gap, initial carb. adjustments, and all other literature concerning maintained and proper operation.
I've got it all put back together and it's surging. I know next to nothing about these machines. I've noticed that the throttle plate is cycling open and closed (a little) in sync with the surging. It surges at all speeds. I noticed this linkage is connected to the governor. I don't know if this is a result of the surging or the reason for the surging.
It seems to surge a little less under the load of the blades being engaged.
I meticulously cleaned the carburetor and can’t believe there are any blockages yet the needle screw circled in red below has no effect.
I ran across this info and saved it for future reference hoping I would be able to figure out what the author was talking about but it’s still beyond me (red text).
“…as it is a 14sb, it has a kawasaki engine on it. when you push the throttle lever all the way forward, check to make sure the choke linkage is closing all the way on the carb. if not, pull the lever back to the fast position and see if 2 holes line up on the plate the cable hooks to. this is the throttle plate. if the holes don't line up, loosen the cable retaining screw and move the cable to align the holes
I've also read "Surging 318 update" Surging 318 update
posting plus all other applicable info I could find but am still at a loss.
Gas, fuel lines, oil (NAPA 30 wt. high detergent), oil filter, air filter and prefilter are all new.
Gas tank, gas valve, and gas filter (at bottom of tank) have been cleaned, but I’ve yet to install an additional, new inline gas filter.
Spark plug cleaned and reinserted without changing gap.
