Too much oil in the mix can be worse for the engine than too little.

Huh? Too little oil makes it SEIZE! Nothing is worse that I know of in
any engine...

A
mix that has too much oil can cause the engine to run too cool, which
in turn leads to excessive carbon deposit build-up, which in turn
leads to hard starting, poor running and at some point, broken piston
rings.
Even my little Yamaha 3hp has thermostats, now. The book says 100:1 on
that motor because Yamaha is trying to wear it out by the end of the
warranty so I can buy a new one. I run it on 25:1 and it runs just fine.

Gotta watch those carbon buildups. Those damned old Evinrudes, all greasy
'round the carbs from 50 years running SAE 30 Quaker State at 16:1. God,
how awful to have a 2-stroke engine that uses those $3 car spark plugs from
Western Auto and needs 'em every 5 to 10 years. Man, I'm glad they don't
have simple, easy-to-maintain-and-fix old 2-strokers any more. Why, you
should see my neighbor pouring motor oil into that pump-up gas tank on his
7.5hp Sportwin. The damned thing has been running like that for 50 years!
Hell, he should be runnin' a Ficht that blowtorches the end off a $20 spark
plug four times a year! How disgustin'!

Oh, oh, waitaminit! I don't remember anyone with those old 16:1 motor oil
engines having "carbon buildup"! We hauled 'em out of the garage as soon
as the ice on the lake melted off, stuck 'em on the back of the rowboat,
plugged in the red steel fuel tank with last fall's premix gas in them,
then pumped the little button on the tank to shoot some gas in the floats
and OFF WE WENT! Nobody had professional engine technicians with degrees
from Evinrude or Merc. Scotty mighta seen a couple of shop manuals over in
his boathouse. I don't remember anyone pulling the heads off to clean
anything like carbon out of the cylinders.....well, unless the screwjacks
got loose and it fell in the lake runnin'.

How absurd we've all become......BRAINWASHED....

The 25:1 in the manual probably refers to the break in period ONLY.
Almost all 2 strokes in recent years have been designed for 50:1.

1997 Mercury 2.5L V-6 175hp sitting atop a Merc Sport jet. Troublesome oil
injection nonsense removed after seeing other sport jets with blown
powerheads from NO OIL INJECTION when the plastic parts seized. Thing ran
like a champ on Exxon or Mobile (whatever was on sale) TC-W3 from Walmart
premixed at 25:1. After several hundred hours, I cleaned off the plug
surfaces with a paper towel and reinstalled them. The guy that bought it
from me runs it the same 25:1 premix I used. Not sure how many hours are
on it, now, but he says it still runs like a champ...(c;

100:1 my ass.......
