I have replace several camshafts on the 310000 and 330000 series Briggs and Stratton engines in the last couple of years due to ACR failure.Its a very poor design.As popular of an engine this is I would think B&S would do something about this issue.It seems that the ACR breaks after the 2 year warranty goes out.Has anyone else experience a lot of ACR breaking.
The broken camshaft ACR seems to be a random problem with engines. I replace a couple a year, one this year just inside of the two year warranty. Never have had to replace the camshaft a second time in the same engine, so could be a ransom issue with the casting or the return spring.
Actually replaced the cam on a honda GC190 last week because of compression release issues, so not limited to briggs.
I have seen many ACR failures on Briggs engines in and out of warranty, some happening on engines with less than 10 hours. Seems like a problem to me as well.
considering they make around a million engines a year, I would expect the odd failure.
Never had one on my watch but I do 4 to 5 head gaskets a year, from still under warranttee to 10 years old.
Do 3 or 4 Kohler Cracks a season
And 2 to 3 Kawakasi heads a year.
The only engines I neve see internal failures on are Honda's but they are twice the price so you really do get what you pay for.
