Bill,

Your response is the power of an active, experienced readership. Clearly, I have no alky experience, and was attempting to formulate a means of dual-fueling an engine. Your solution makes...

Your guess is as good as mine, but 4-5 minutes minutes one would think.

Wbat abour the same carb, same alcohol jets, burning methanol mixed with TCW3 for the last few minutes to wash out castor?...

If the gasoline is only for cleaning & rust preventative, why not use the carbs for methanol only and separate injector system for the gas/oil mix to be used for shutdown only?

Sorry, but I sent the wrong information. So much for short term memory! See below:

Gasoline - Gasoline is what most of our cars came setup so it's usually what we stick with. Gasoline is a...

Possible, but gasoline burns at about 12.5:1 fuel-air, methanol at about 7:1. How do you propose to make up the difference in flow required?

Thanks for the excellent articles and great thinking: Your suggestion for dual oil feed makes fantastic sense!

This effect was accomplished in my turbo OMC as a by-product of fuel selection: At...

For those of you that have "Iron Fist" turn to page 296 and read about port clogging in the MK75 endurance event. It says ports were closing off while running at 4500 RPM with oil of the day (not...

Excellent indeed!

Having been in the marine business for 40 years (OMG am I getting old), I've got to say the engines, oils, props, everything has gotten way better. My Super 10's ran 16:1, later...

Why would air vs water cooling make a difference?

Hey Yellowjacket: The test Z refers to indicates power begins to suffer under 18:1 to a limited degree, but without fear of bearing, ring, and cylinder damage. Most of us would rather suffer 1-2%...

Thank you for the data! The motorcycle article speaks volumes: 2-stroke mechanics routinely see evidence of the "river" oil that flows through an engine. Though crank wheel references don't apply...

This thread offers great reading, and I'm certrain there are terabytes more data available, but a few tech questions should be addressed to make oil purchase and mix ration decisions:

1) For all...
