RE: 4-STROKE VALVE ADJUSTING QUESTION
Triumph cars eh ! Yep I had me one of those, a 1966 TR4A and a 1956 MGA, wire wheels and a continental kit on the back of all things and a 1957 'Vette and the list goes on & on, man I wish I had them all in my driveway now. All of my racing was done in a straight line or a circle, a 1/4 mile at a time. By 1973 the first "Kid" came along, I was broke and I had to give it all up. In 1984 that "Kid" fell into model airplanes and I followed, I've been having a blast ever since. As I say about my YS engines, R/C is a lot more bang for the buck.
