RE: RC Car Actions "How to port a Nitro Engine"
Here is a pic of the K4.6 block looking down the hole into which the carb goes into. In my effort to accurately calculate the induction timing, I need to know what the width of the port in this block is. This is the width of the port that is adjacent to the crankshaft. I cannot put my dial calipers far enough down in there to measure the width of this port. Anyone have a clue on ow to measure this port in the block?
