Greetings, My name isXXXXX and I am here to help the best I can. My goal is 100% satisfaction. Let's get started.
Very likey it is a very simple problem or one rendering the engine not worth fixing
OK, just kidding
likley you have lost a governor spring or it has just popped off and is just hanging there
The engine numbers you gave are not particular helpful
would need model number and then the type number and then the serial number
If it is a Briggs engine the model would be much like
and the serial number woudl be 01646546546 or something like that
But anyway, the only reasohn I would need the numebers if I need to help you get parts
Or if a diagram is needed to help hook the governor spring or linkage up right
If the spring is missing, you have to go buy one anyway
so, If one of My customers were smart, they would play dumb
and bring the entire mower in and say..
Can you help me to get the right governor spring for this engine
then once I had the spring in my hand, they would say "how much to install it".
If I am standing in front of a mower with the cright governor spring in my hand, if offerend $10 bucks to throw it one and make sure it is hooked up right, I am hooking it up...
Takes 45 mins if you do not know what you are doing
and 3 minutes if you do.
IF it is not a governor spring issue, then likely you have broken the governor gear inside the engine and it will need replaced
the gear is cheap, the repair is a pain in the rear and takes 1 hour to 1 1/2 hours start to finish
It is in side the crankcase and requires removal of the base plate.. You would need to make sure the gear on the cam shaft is OK..
AND, if it were me, I woudl replace the rings while I was at it to account for any wear over the past 10 years and regain engine power
Having saidf that.. It is likely a spring or linkage problem.
You have found the numbers, I think
But you may wish to check them again. The above shows all known model type number combos... (2 short pages).
But even then, you could click on any one and be likely to bring up a carb, linkage, and control diagram set that may help or at least let you take inventory of something missing..
I just do not show a 0269-E1 as an option for the 124602
I found this which may also help..
It is a complete service manual for this engine.
And other engines in the same series..(Not exactly the same).
