I have noticed the cams are wearing badly in some of the ohv engines, between 14hp and 17 hp single cylinders,adjusted the valves in a 17hp briggs
yesterday didnt help the running it still loped,but got it tostart and run.I TOLD THE CUSTOMER it needed a new cam,he said it had run like that the first day he brought it home and left with it running like that.Replaced three cams last summer,lobe on exhaust wore clean smooth on one of them.Anyone else noticed this on briggs.

If it's a newer model, cams are probably made of plastic nowadays... LOL, you guys know how things are made thses days.....

.....valve springs could be too strong, and is wearing the cam......

.....I dunno, unless the valves and cams are made out of two different metals, one wears faster... under heat....compression....??

Thats Unlike Briggs..... Mabe a Honda (no offense).

I think its the softer metal they are using in the cams,replacement cams were of better quality,by the way the replacement cams were genuine briggs parts,where the cams came from during factory installation who knows, with all the out sourcing going on these days,mexico, china, who knows.

18.5 HAVENT experienced them yet, working on a 3 year old craftsman right now 17 hp briggs that needs cam, when sears sold it to the guy it was loping when he brought it home, amazes me it ran that long without major inside damage.I CAN TELL YOU these engines all have one thing in common, they have the plastic flywheel cover that surrrounds the metal cover underneath,personally I THINK THEY ARE ASSEMBLED IN MEXICO.I prefer to work on briggs, think its overall still the best value for the money,kohler just uses roller bearings on each end of crankshaft,increases the life of the engine, parts are to expensive in my opinion. 11hp briggs best they made,leak oil from bottom crankcase gasket, but it hardly ever slung a rod.16 hp twin vanguard, one tough twin cylinder.12hp synchronizer on crankshaft, if it goes to knocking, piston rod is soon to break and knock a hole in block,saw a lot of 12 hp sling rods

Thats why I myself like briggs, cheap to buy, cheap and easy to fix, and last almost or just as long..... Lol, have a 17 year old 12hp I/C single cylinder, I'm the third owner, gonna rebuild it in a couple years or so maybe, I beleive the oil control ring is broken or worn out, that and the exhaust valve has started to leak oil...., but still keeps going, and I like to pull on the string I have tied to the governor alot....
speaking of briggs, I just think this goes to show how tough they are .. ( http://youtube.com/watch?v=GL1tA8FXmkg ) guy put a 60 shot of nitrous on a stock briggs engine. Also have a 8hp briggs from 78 I beleive the code states, on a murray (when they actually were good) things still going strong, has had the ignition conversion done to it, and its a synchro balanced engine,... has it boldly stated on the hood like it was a big deal back then..
