I believe I understand your objections to this modification, that hot gas will escape from the combustion to the intake chamber and cause the intake charge to ignite much too early, Lynn estimated this to be as much 100 degrees before top dead center (I assume this term is just as applicable to a rotary as a piston engine). Keeping in mind that I have only one data point with rotaries that I can expound upon from experience (see next paragraph), can someone direct me to anyone who has performed this modification and run it? I've looked all over the auto rotary sites and got no replies based upon experience. I don't have the knowledge to judge the accuracy of the opinions given, although I can certainly understand the logic. Rick's one data point: The "el cheap" motor stand from Harbor Freight Tools fits a 13B rotary with an auto TX flex plate. The standoffs on the arms of the stand fit right over the two locators on the flywheel mounting surface and give about a half inch clearance to the flex plate. I snugged the arms up lightly as I put the four mounting bolts (10-1.75 X 75mm. The one going in the bottom right blind hole must be shortened 12 to 15mm or it bottoms out short of tight), then loosed and retightened them one at a time after the engine bolts were tight. Total price was about $50 after buying the stand on sale and picking up the metric bolts at the local hardware store. Great for rolling the new "Art" around the living room.
