Briggs & Stratton Model 252702 Engine

[Vizslaman]

This is a bit of a long shot but does anyone have a manual for a B&S 252702 Engine.
I have searched the B&S website and managed to get a parts list but not an owners handbook/manual.
Also does anyone know the power rating for this engine ?.

What do you need to know?

Have you any photos of the engine?

 

[TripleSix]

Had a search about.

Vertical crank?
It'll be 10 or 11hp.

 

[Vizslaman]

Yes vertical crank,soft spin recoil start.
It is fitted to a walk behind flail mower

Oh poop, someone on here used to tinker with them

I'm a time served horticultural mechanic by trade...

 

[Mursal]

Is it giving trouble, then?

 

[Vizslaman]

It has not been run for 6 years, so just trying to find out as much as I can before try starting it.

My plan is to remove fuel tank and clear any debris, replace the fuel line, strip and clean carb. There appears to be a healthy spark

 

[Mursal]

OK then so .......................

I'd wet the plug with a sup of petrol, (sprinkle a few drops into the cylinder, as a treat) top the tank up, check for oil in the sump and give her a pull?
They just dont give trouble ............

Chuck it away they pure junk and buy a honda,life is too short to waste on them things.

I would drain the fuel tank, then drop the float bowl off the carb and clean it.

Add a bit of fuel to the tank, check it piddles out the carb.

Refit float bowl.

Add more fuel, try a start.


If there is a large amount of gunk in the float bowl the main jet might be blocked...

I,ve a syringe in my tool draw for dribbling fuel down plug holes

that was footsfitter on the old forum

They are old side valve engines so a decent head gasket helps With them

 

[Mursal]

But the head gasket wont deteriorate while lying up, but the head bolts are known for coming loose in service.
Leaves them a tad hard to start .............

 

[Vizslaman]

Well I have managed to get a parts list and owners manual from Briggs & Stratton.
I removed the carb to give it a thorough clean (just as well because float bowl was full of rust.)
Whilst waiting for the new gaskets etc I removed the fuel tank and replaced the fuel line so all being well the fuel side should be OK. There is a decent spark at the plug so once I get the new gaskets I do not see any reason why it should not start.
According to Briggs & Stratton this engine was made in 1979 and was rated at 10 HP

Have you good compression?
Consider a drop of oil in the cylinder to help the rings, if you think its cranking over a little easy.
Lying for the few days while you wait for parts will let it soak in well.
