OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines Electrolux 380 (B&S 380)

Hi All,

This mower has been faultless except for a very very low idle speed. So, i tweaked that a little by removing the starter and ever so slightly playing with the spring. Great, it worked well , yet not overrevving or getting too hot.

Now, ive some how managed to stuff up the pull starter. When i replaced the unit and started it, it made a god almighty sound like the shaft was spinning inside the white plastic starter. I removed the unit and its chewed out a fair bit of plastic. The pull cord didnt appear to retract well either until i had removed the starter housing from the motor.

Does anyone know if just replacing this piece would suffice and why this occurred in the first place?

Does anyone know the part number for this?

Thank you
Kris

its a square shaft on top of the engine ? if its not fitted correctly it will chew it up fast , or if its the throw out pawl type ? you might have left a pawl sticking out when was fitted and chewed that out .
what type is it ?

sort of sounds like it might be a quantum , and numbers or a photo ? its the easiest way to tell

a Briggs 380 is a rebadged sprint 375, generally earlier type with the square clutch starter. It's quite possible that the starter clutch has come apart slightly as its been disassembled.

Some pics would be handy to give guidance

hmmm, I just scrapped one that had that exact problem. It was the square starter pulley was knackered. A high pitched scream? Easy fix though. Just need a new starter pulley.

If it is one of the ratchet starters as below:

Then the center drive can be slightly bind to crankshaft. Sometimes all is needed is oiling thru top hole to re-lube the felt pad. Other times the top of the crankshaft is damaged and require filing down the high spots that is causing the binding.

I have seen these to be screamers and even destroy the recoil springs when they are binding.

Hi guys thanks for all the replies. I'll get some photos tonight of the bits and pieces.

Mines the type above with thr square shaft.

Hi Guys, here is the starter in question

Are you missing two bolts there? Or is it slightly different from the one pictured above?

If you're referring to the bolts that hold the mesh down, there's only is 2 bolts in them from factory. If you strip or break them, then you can use the other pair of holes.

So guys, any idea on what I need to replace?

Depends how much got damaged. With your initial description the starter pulley needs replacing. With the possibility of the recoil spring and starter clutch but you need to remove the starter clutch and try find out why it tries to stay engaged. As said it could be a dried out oil problem, or it could be binding on the top of the crankshaft. Usually with it trying to stay engaged it will squall a lot with possible pulley and recoil spring damage.

If you remove the starter pulley it need to be re-torqued to 55 ft-lbs. Use a torque wrench and not the hit it with the impact as it can damage the flywheel.

For actual part numbers we would the model, type, and date code to look-up those. These are usually locate on engine tins.

Thanks AVB, its very odd that its suddenly gone faulty when i just removed the starter/engine cover.

Ill post up the engine number/model/type this evening.

Pulled this from another thread..

Model: 98902 Type: 038501 Code: 95100352

KrisK, are those numbers the ones on your engine? That's not quite clear.

Yep, the info pulled from another mower of the same type.

Anyway, in the interests of time ive got a mechanic coming over (mobile type) to sort it out. Too much hassle Thanks though!

OK, fair enough.

But I should mention, for future reference, that the numbers off the actual engine being fixed are what's needed, as parts changes do occur during manufacturing runs. Even of the one engine model. B&S tracks these by the Code numbers in particular.
