I've not contradicted myself at all.
In regards to question #1. You research that yourself. My statement stands until you prove otherwise. I have no sort of morbid interest on it other than I know it happens as I described. In addition I believe you know it happens too. (edit - MOD)
No need to curse just answer the question. The choices would be - the value is XX degrees, or "I don't know."
In regards to Q2.. as I have stated repeatedly now... Premixed fuel enters the crankcase in liquid droplet form. The heat from the motor changes the phase of the gasoline component of the pre mixed fuel into a gas and the oil is thus deposited on the rotating assembly by virtue of the fact that two cycle oil changes phase at much higher temps than gasoline. Proper lubrication is dependent on this change of phase as gasoline(a solvent) and 1.96% oil(50:1 ratio) has nearly zero lubricating ability. Likewise combustion is dependent on the gasoline being in a gas form prior to the sparkplug firing as liquid fuel will not ignite. This is detailed in an article I posted by a Harvard physics graduate BTW.
Are you grasping this? A simple yes or no while suffice. No need for a several hundred word diatribe in regards to a very basic concept that has been known about for a hundred years. No deflection or redirection, just a simple answer.
In addition to this. You do realise that any IC engine has to phase change its fuel prior to combustion occuring? In a 4 cycle gasoline port injection or carbureted engine this happens in the intake runner. In a GDI engine this happens in the combustion chamber. In a DI diesel it likewise occurs in the combustion chamber. In a two cycle it occurs in the crankcase.
The viscosity of the the oil once inside the motor is the viscosity of the oil prior to mixing with gasoline minus the effect of any solvents added for miscability. On other words fairly thick.
In post 64 you incorrectly understood viscosity and a lubrication concepts which I had to correct:
"Gasoline has an average viscosity of 0.75 cSt at 40C, 2-cycle oils average about 46 cSt at 40C (about a 20 grade).
At a 40:1 ratio there is no way the final 2-cycle oil/gas mix is going to still be a 20 grade oil going into the engine.
The reason for this is once the fuel/air charge enters a two cycle motor at operating temps...
The fuel mix enters the engine at a bit less than atmospheric pressure and at about atmospheric temperature. The carb atomizes (breaks fuel into small particles), it emulsifies (mixes fuel with air), and then vaporizes (changes into a rarefied form).
The carburetor is what creates the phase change from liquid to vapor.
the solvent in the oil and the gasoline changes phase from liquid droplets to vapors and thus deposits the two cycle oil of the pre mixed fuel on the rotating assembly. As you noted the viscosity of premixed fuel is very low and in additional has very little lubricating ability. If not for this phase change and the resulting deposition of oil the engine wouldn't last long.
A combination of the oil's base mix and the additives in the premix is what lubricates the rotating and reciprocating components."
In post 65 you said, "Vapor is the only thing the spark plug can ignite, so a choke is also used in a effort to flood the motor with enough fuel so that enough vapors exist that they can be lit off. " In 102 above you said, "Likewise combustion is dependent on the gasoline being in a gas form prior to the sparkplug firing as liquid fuel will not ignite." So what ignites in combustion, the vapor phase or the gas phase?
In actuality, the carb converts premix and air into a vapor, after which the piston moves down to compress the mixture. This compression, which you never included in the process, raises the temperature of the vapor; plus the residual (added) heat from the crankcase increases the temperature of the mix to form a gas which is ignited at the power stroke
In post 90 you said, :"Hint..its not lubricated by liquid gasoline with a smattering of oil in it. Its lubricated by oil deposited when the fuel entering the crankcase changes phase from a liquid to a gas." So in your scenario, the oil somehow magically separates from the premix and deposits on the rotating components.
The fuel/air mix enters the bottom part of the crankcase as a vapor (see my comprehensive explanation above). As this point the fuel-oil droplets deposits on the various components, lubricating them. A short time later, the piston moves down to compress the vapor below it; the
combination of compression and residual crankcase heat results in a phase change converting most, but not all, of the residual vapor to a gas. As the piston moves up the gas below the piston is allowed to enter the "combustion chamber" for ignition, the power stroke.
What you need to do is to actually read and understand what is stated, and to increase your understanding of the physics and chemistry of this process and the timing of these processes.
