Gil,
To go at this a little 'backwards' . . .

We're NOT talking about 'precision engineering requirements' here. The
proper oil ratio aside, 'Gas is Gas' to a 2-cycle engine. I wouldn't worry
about tetraethyl lead, Ethyl Alcohol, or 'winterizing' additives - on this
score.

However - always one, sometimes hidden in the weeds - engine EXHAUST is
another issue - entirely - for ALL 2-strokes. From a purely mathematical
'Fix or Repair' analysis, 35 percent of new cost used to be the figure. This
presumes a repair that will LAST a good ling time. Also that you are not
just putting 'Band Aids on a broken arm' - you are going to get a 'domino
effect' from the new STRONGER part putting pressure on the older, weaker
parts causing THEM to sequentially fail.

In this case, at SOME point you ARE going to have to get a 4-stroke {or
whatever has the least impact on the environment when you buy}. They have
been on the market for several years, so the first thing I would do is shop
around for a new 'left-over' from a year or two back to this past summer.
Next would be a 'Used but not Abused'. {Logic says NOW might be a good time
for inventory bargains. Or AFTER Christmas . . .}. While you will pay more
from a local dealer, a warrantee or some kind of written guarantee is
likely. IF you are 'engine savvy' and have the tools . . . the open market
{ebay, 'craigs list', etc.}is always there.

After you get a 'feel' for the pricing in YOUR area . . . the decision MAY
be easier.

Regards & Good Luck,

Hey guys and gals -

SNIP
Anyway...as most may not know, my Suzuki DT140 (1985) two stroke, oil
injected outboard motor got burnt (internally) probably lack of oil
circulation or cooling system . . .told it will cost over $1,000.00 for
repair.

All of you, compairing the pro and cons of repairing the motor for less
than $3,000 or go for a newer engine (avg 7k to 10k dollars). SNIP
