I just ran apc gray plastics 8x5 14200 9x4 13200 they did not have an apc 8x4 in stock is was quite clean running not a lot of smoke
and more manageable now with a little more time on it no "wandering" did not have to mess readjusting the needle or compression
which was fine with me those apcs at that speed scare the p**s out of me. after being chewed up last year do not need an other ER visit
I was VERY careful adjusting the needle not much room between it and the prop, At this point do not see the need to cahnge to the ASP
twin needle carb. It will be intresting to see the numbers with the exhaust rings when they come. I do like the beefy rods compared to the PAWs martin
