well, as long as you check oil, youre pretty much fine. briggs quality is very hard to beat by some clone
Why wouldn't you check your oil?
As for clones not lasting as long well...... Have you taken both a clone and a late model Briggs apart? I have, the castings of the clone were actually quite good quality, I can't really say the same for the Briggs. Whilst the the Briggs castings were accurate and with out fault the aluminium it was made from was quite soft and porous, not a good thing, especially with an aluminium bore. The stuff that was bad quality on the clone was the tin work and throttle mechanism, the tin was poorly stamped and the throttle had broken, it was easy to see why too. The Briggs tin work was stamped much better but was quite weak, a few of the bolts had pulled through from when it had been pull started so I had to solder washers over where the holes used to be. All the linkages were still good on the Briggs though.
The thing that really got me was the clone has ball bearings and a cast iron bore, the Briggs had bushings and and an aluminium bore, so why does the briggs cost twice as much as the clone?(clones cost about $250 here in aussie land) I'm not really sure. It should really be the other way around. What's more, the clone has more power and is easier to start than the Briggs, used less fuel too.
So, the engine that is more technically advanced in every way and has higher quality castings wont stand up to the power you think? By the clones basic design it will make more power than the Briggs and say they were both making 10HP, I think it's fair to assume that the clone would be less stressed making that power than the Briggs.
Sure, older Briggs were pretty good quality, say pre 1990s ones but it's unfair to compare engines of different age.
Not having a go at you mate, just stating my personal experiences. I don't particularly like the clone engines, I don't really like Briggs either, I just don't like it when people assume things because of a general stigma around something.
Thanks
