SNIP


Â* Since all my 2 strokes are Stihl (except one 45 yr old Homelite
chainsaw) I buy their premeasured bottles . 12.8 oz per 5 gallons , I
use a 2.5 gal container and half a bottle . I also mix my gas (87 oct
reg and 92 oct premium , both non-ethanol) 50/50 since Stihl recommends
89 or better .

Echo also recommends 89/mid grade octane for their two-stroke machines.

I could never figure out why such low compression engines would need
anything more than regular grade 87 octane gas. Is pre-ignition really a
problem?

Echo also recommends using a higher grade of two stroke oil (ISO-L-EGD
(ISO/CD 13738) and J.A.S.O. FD) instead of the cheap sludge I've always
used in my 1960's vintage 70 HP Evinrude outboard that's still running
like a champ.

Nonetheless, I've used the Echo-recommended oil in all my Echo lawn
tools and they too are working fine.

Has any homeowner actually ever worn out the engine on a weed eater?
They usually get tossed because of other things, just like cars.


Yup , got one the neighbor wanted fixed . It still ran , but only at
around half power . Had as much suction as compression when you pulled
the rope .

Sounds like reeds.


That trimmer motor has no reeds , the rings were so worn the most of
the compression was lost by TDC . No other way that I know of it could
have suction on the downstroke .

OK I really have never taken a little 2 smoke apart. I just know old
outboards.
