Thats the fuel pump body.

If the cover plate has 4 screws Briggs P/N 693487.

If the cover plate has 3 screws Briggs P/N 691896.

True newz =) but thats how i got into engines =O took open my honda... scored plug super black no spark almost no oil but dipstick said full >=( and stuff,,, then bought a 2 hp briggs.. thats how i began!

 

[tommyj3]

I agree with newz somewhat, but I think the purpose of this forum is to help others out that don't have the knowledge to jump in to some projects.

[tommyj3]

I agree totally.

 

[oscaryu1]

yup now that you say it... i agree

Guys I know what im doing. I was looking for a techincal term. Its working or should i say did work for 3 hours. It ran outta gas and would not restart. I checked everything for spark, changed the plugs ( one of them looked rich the other was smelling like gas) It will run for about 1 min but horribly on 1 cylinder and barley stays alive. It also is spitting gas back up through the throttle body into the air filter whcich leads me to beilve its possible a exhaust valve is stuck.

 

[oscaryu1]

well good luck =) ive never messed with a exhaust valve stuck DOWN but ive gotten valves stuck up

 

[kodiak956]

Well why then am i getting pressure back up through the carb?

 

[oscaryu1]

dunno maybe theres carbon buildupin one of the exhaust valves

 

[kodiak956]

hmmm. Has anyone here taken apart a briggs v-twin? how hard is it to get to the valves?

 

[tommyj3]

Kodiak956 check your valve clearance.

Intake valves min .006 / max .008

Exhaust valves min .009 / max .011

Sounds like the intake valve is sticking or the clearance is to tight.

Valve Seat

The engine you posted model numbers for is an opposed twin, these engines have had a history of problems with the valve seats coming loose, this could cause a problem similar to the one you describe.

Determine which cylinder is causing the problem and remove the cylinder head and inspect the valves, seats and overall condition and you should be able to tell what is causing the problem (loose valve seat, stuck valve, excessive carbon build up, etc...)

 

[kodiak956]

Thanks 30 year tech... You would not happen to have access to a service or repair manual would you? What is the fix to these problems... how hard and long do they take and how much money? Is it worth doing my self?

 

[oscaryu1]

depends how good you are at engines, like me in a kinda beginner, with knowledge =-) google the info
