Small Engines (Lawn Mowers, etc.): B & S 124802-3219-01 engine, mechanical governor, primer 3

Question
I assume I'll need to disassemble the carburetor to find out if it's a float style carb, right?

Question -
I just was given a Murray 21775C lawn mower with a 5hp Quantum XTE 5H engine. Model 124802-3219-01.

My friend told me it hasn't started for 4 years. Would this entail rebuilding the carburator? If so where would I get a manual for the process? By the way it does have a primer, however when I press the primer 3 times as told, gas comes out of the hole in the middle of the primer button.

Thanks for any help.
Answer -
I'd definitely clean the carb and you will have to replace the primer bulb based on what you described.
As for the manual, any Briggs dealer will have a factory repair manual.  The Briggs manual you purchase is the same manual as we use in the shop.
Is the carb a float style carb?
Let me know.

Answer
According to the model number, you have a flo-jet carb with a mechanical governor.

So the carb should be a float style carb.  These carbs are very simple to work on.  I'd remove, disassemble and clean the carb with compressed air and carburetor cleaner.

If you have a needle adjustment on the front of the carburetor be very careful not to over tighten the needle.  Over tightening can damage the carburetor.  Use a very small screwdriver or your fingers to GENTLY seat the adjustment needle and then back it out 1 & 1/2 turns for an initial setting.

Let me know if you have any questions and if it works.
