I now understand the problem here! However I don't know how to fix the problem.
I was explaining to a friend how the reed valve works the other night and I see exactly how this fits together with thiis problem.
When the piston goes up it creates a vacuum in the crank case which unseals the reed valve and sucks the fuel air mixture into to the crank case. It needs all of this vacuum and the volume as well to get enough of this in there.
When the piston goes down it creates pressure in the crank case which seals the reed valve and forces the fuel air mixture past the piston via the cylinder port/s. It needs all this pressure and volume to achieve this properly it seems. This last statement very well may not be true for the Tee Dees can run using crank case pressure and do so successfully. More on this in a moment.
By 'stealing' some of this pressure the reed may not seal completely nor deliver its full volume of fuel air mixture into the cylinder as it should.
Attached is a picture of a Cox twin cylinder that can never be made to run because it will never create any vacuum in it's crank case so long as the pistons are alternating. On the other hand, if the pistons were to made to fire at the same time and down stroke at the same time, there would be vacuum in the crank case as it should have
When you tap a Tee Dee engine, the difference is this seal is made by the crank shaft! As for the volume, I mentioned before, this doesn't seem to hurt a tapped Tee Dee in the least so I think the problem is in the reed/seal department.
Larry, the RR1 is rather a valuable engine and I have always wanted one but have not been able to afford one. Do you think the rotor seal in this engine would work better? I think so.
