I can't find "search", or an engine forum, so I'll ask this here. Briggs twins: good engines or pieces of junk? I'm looking at a tractor that the guy says the 16 horse B&S was swapped for an 18 horse B&S. Which engines are good, and which ones are to be avoided (like a KT17)? Currently waiting on pics of the engine to find out what type it is. Thanks!

I guess the main thing is how well the engine was cared for over its life, if its an older machine (80's) its likely a L head engine, from my experiences those are very solid built engines

From the owner: "The engine is a 18 Twin I/C Industrial Commercial, Cast Iron Bore engine." We have one on a start-all at work but it is the only one I've screwed with.

I have five Brigs L Twins. three horizontal, two vertical. I may be biased, but I like them. Easy to work on, and reliable. As long as maintained well. See if you can get the model number off the shroud and post. I dislike the overhead valves on the V twins.

I always told myself that I wanted the Kohler or Onan in a big L head twin, but after many experiences with those and the Briggs, I have had much better luck out of the Briggs twins and they always seem to be regarded as a lesser motor. They may or may not be quite as heftily built, but they sure do seem to run smooth and not nearly as finicky.

You can get roughly 2,000 hours out of a L head twin if it's a cast iron bore block with decent maintenance.At around 2,000 hours you'll notice they will be down on power and will have a good bit of blow by.
No they don't last as long as a kohler or Onan twin but parts to rebuild them are 1/4-1/2 the price.Kohler L head twins can run up to 3000+/- hours on them with regular maintenance before needing rebuilt or replaced.(except the KT17 series 1 but even that engine will last a long time if it's kept stationary lol)
The aluminum bore briggs flat heads I would stay away from.Rings and cylinders wear ALOT faster in those.
I've seen a couple ohv Vanguard twins with 600-800 hours on them that smoked from worn rings and a couple with 1600-1800 that ran good with no smoke so it's a crap shoot.Some good some bad.Might have something to do with certain lower quality Chinese parts?

I have a good stock of used BS twins from freebee LTs with unknown hours that I use to power projects or to repower LT flippers. The best thing about them is they are easy to come by, easy to get parts for and dirt cheap. If I get one with internal problems(doesn't happen often), I just swap it out with another one.
