Thanks Bobby

Great info about titrating the pre-mix amount.

I assume that what you mean by "making sump oil refers to the oil level in the sump increasing with use. Am I correct?

What I was referring to in my last post was the break-in process and the oil to be used as a pre-mix.

Thanks again,

Rich,

 

If you are not using sump oil injection then I doubt you will ever see any carbon build up. We run our engines at high rpm. You start two stroke at a mixture around 1oz per gallon. Then reduce that amount until you stop making sump oil. I was still make sump oil at .8oz per gallon but didn’t reduce any further. With the constant speed prop and super charger I could run lean mixtures and 30-32” MP for hours at a time. I wanted extra oil in fuel. A little water through the intake will not hurt. I ran water injection for takeoff above 35” MP during the Texas summer. 100cc per minute. A freshly overhauled engine should have zero carbon buildup.

Head still breaking-inImage removed by sender. Unamused


Len, just to clarify,


Do you mean to put an additional 1/2 oz per gal conventional oil in the already added premix (about 1.5 oz total pre and conventional oil?).


Additionally in a newly overhauled engine do you still recommend the water technique to get rid of the carbon created by the break-in period of the oil mixture.


Additionally additionally is standard oil miscible with both pre-mix and fuel?


Additionally additionally  and as well---Do you think that the water treatment should be done periodically and if  so how often?  When I rebuilt my motor after only about 14K the rotors had significant carbon (which was a bit#h to remove.) perhaps to do the water as a prophylactic treatment.


Thanks again again, again

Rich

Cheap conventional oil in the premix at about 1/2 ounce per gallon as well as in the crank case. The round rings are oil scrapers and are supposed to keep crank case oil out of the combustion chamber, same as a piston engine. Do not tell anybody about this.......with a warm engine at 2,000 RPM...slowly add 1 cup of water to the intake over several minutes. It will remove all of the carbon from the rotor face and free up sticking apex seals in most cases.  Works on piston engines as well....like MAGIC. Saves hours of scraping. On street cars it will plug up the reactor.....with carbon crap...........
