more info you requeted
there is one spring (long one) on the left side of the engine. I'm trying to figure out where it attaches in the front. does this help?
model is 11A-18MC056
serial nbr is 1J177K30028 000001
top of mower says OHV 173cc/6.75 ft lbs.
Hello. What is the model number off the engine? It should be stamped in the sheet metal above the spark plug.
no sheet metal above spark plug
closest thing had JT-06-06-03
Is this a Briggs and Straton engine? Is the carb made of plastic?
all I can see is MTD products
also the carb is metal NOT plastic.
You have the Chinese MTD engine. That long spring keeps all the linkage tight. It goes into the same hole that the governor link is in. Throttle shaft and governor arm holes.
