Hi guys
I have a B&S Quantum XLS50 Push mower with Cord Pull Start.
Engine number 12F802-1783-B1
I push the primer 3 times and it takes about 20 vigarous pulls to start.
I've checked primer bulb, inside the carb,air filter is clean, spark plug OK.
The Spark Plug Connector was a little rusty so i've scraped that with a screw driver.
The Gasket between the Air Filter & Carb was a little torn, I've ordered a new one. Could this be my problem ?
Should this model have a Gasket between the Carb & Engine ? There isn't one fitted, it has a sealing O ring but I can across this Carburetor Gasket 272199S Order now for same day shipping. 365 day return policy. RepairClinic.com
Should one of those be fitted between the Carb & Engine ?
Thanks For Any Advice :cool

Thanks for the excellent replies guys ! :)
As I said, I've ordered a new gasket for beyween the Air Filter & Carb.
I've also ordered a gasket for between the Carb & Engine.
Would fitting this extra Gasket cause any problems ? The O ring does look OK

Thanks Again :)

I've just fitted a new Air Filter to Carb Gasket but still got the same starting problem.
I've removed the Air Filter, looked through the Carb hole & pressed the Primer, I'm not seeing any fuel coming out of the Brass jet in the Carb.
The Primer Bulb looks fine, it has a manufactured hole in the centre of the bulb, which I could never work out why ?
Would i be better with a new Primer Bulb, one without this manufactured hole in ?
Thanks Again ;)
