Re: Eska & Tananka, what the ?
<Tom, I once was young and so were you,>
But that was a loooooong time ago for me!
<---did you know there were 2 cycle engines with with valve's like a 4 cycle? I didn't tell a few days ago...>
Actually I did, but I was blessed (or cursed!
) with an insatiable curiosity.
The very 1st internal combustion device I ever owned was an ancient Johnson outboard when I was 8-9 years old (in retrospect quite probably one of the first models Johnson ever built) given to me by an Uncle who wanted to feed my fascination with the boating which he loved. Like most kids I tore it apart and never got it back together, but it inspired me to research IC engines. By the time I was 13 I was able to turn two 5 gallon buckets full of rainwater and engine parts into a running (sometimes!
) 2 cycle motorcycle during summer school vacation.
<----kind of like multi ratio 2cycle oil I really don't understand yet...but I will if someone teaches me>
Now you bid fair to get me launched onto one of my spirited diatribes about 'snake-oil salesmen'! Never---and I do mean NEVER---buy the hype that some new 'magic' lubricant can adequately replace the fuel/oil ratio recommended by the engineer who designed an engine!!!!! The man---or men---who design an IC engine know better than anyone what will be required to PROPERLY lubricate their design and keep it running into a graceful old age. Oil is one thing but the basic metallurgy of an engine and bearings is a totally different matter!
Example: Johnson/Evinrude brought out the 3 horse twin in the very early '50s of the past century. It had plain bronze sleeve bearings in all places where a bearing was required. The recommended fuel/oil mix was 16/1. But Mercury started advertising "Fully Jewelled" (meaning ball, roller or needle bearings) engines shortly thereafter that would run well into old age with much leaner oil proportions. Since they soon took a big bite out of OMC sales the OMC SALES department made the decision to change the suggested fuel/oil ratio for the 3 horse and other plain bearing engines in their line to 24/1 in the late '50s followed by even leaner mixes a bit later. The plain bearings in the Lightwin/JW series never changed----only the recommended fuel/oil ratios.
Since I have a weakness for the 3 horse OMC twins I've acquired quite a bit of experience on just how that worked out. In short I MUCH prefer to run across an early 3 horse. Even if they have many more hours on them than the later models running a thinner mix they virtually always have better compression! I just bought a powerhead from a first model Evinrude model 3012. It has compression in the mid 90s! When I finish the repaint it is slated to replace the worn-out powerhead on a cosmetically near-perfect, extremely low hour '58 that was operated by someone who bought into the snake-oil sales hype!
I suppose that's enough rant for the day. Just sorta sorry that the OP failed to understand that I was exercising 'tough love'.
If the ancient wisdom "ignorance is bliss" is indeed true then he must be a very 'happy camper'!
