nklr twingles

Ok I Loosened the screw didn't hear no click then tightned it down snug. My question is what is snug?? I turned the screw till it stopped. Is this too far? This is the first time I touched this screw and when I backed it off it seemed loose to begin with not sure though. Can some one take a measurement for me with a toothpick or something to see how far out the screw is from the case? Or mayby the torque value? I'm reading all of the horror stories in the archives and getting nervous. Still have the slight rattling noise. Next I will try the valves but without a book and torque wrench I will wait. Thanks again. Van A7

Twingles cam about as two strokes well before the understanding of the Lop Scavangel system was understood. The idea of the twingle was that the wall between the cylinders woiuuld block the charge flow from going straingt out the exhaust from the intake. While the inertial effects of airflow were vaugely understood..the concepts of the coanada effect and how to take avantage of it were not. nor was the value of swirl and turbulent flow known. the intake piston was timed to nearly the same cycle as the exhaust (the differance is due to the rocking of the u shaped conrod. this keep the supercharging to a minimum. A similar development is the domed pistons popular on old outboards. as for running ccharcteristics. both the domd and twingle tend to run very weel at low speed then flow very poorly at high..and they idle well. the Loop Scavanged systems (modern 2 stroke ic engines....deisels are another world.... idle poorly and runn well at high spped. this is because the lopp scavanging is designed to take advantage of gas interial and some ability to point the charge through the coanada and inertial effects. modern loop systems are degined with hiigh squish levels to promote turbulent combustion...this was unknow before the early 50s.

Faded memory can't remember whether the balancer tension screw can be removed without removing the side case. O-rings are leaking. Trivia extra points for size of the o-rings from memory. Thanks, Todd [Non-text portions of this message have been removed]
