I like my needle valves on the carb also, the angled ones that TT, Moki and others use are a plus.

I like the bronze glow plug threads that OS used to have and ST still does. They wear better.

I like the ST swing mufflers, after drilling out the rivet that holds the baffle and discarding them both. Their mufflers are still pretty quiet without the guts.

I hate OS and MDS mufflers that break in flight and lose their back halves in the tallest brush, never to be seen again!

I like YS fourstroke engines, their power and throttle response is a cut above all others. The price for this is they are thirsty and require premium glow fuels.

I like true ABC BB engines that dont cost a mint to purchase, like ST

I don't really like plastic parts on my engines, Throttle arms and perry carbs are okay, nothing else though.
