[QUOTE="Rick Stephens, post: 6723015, member: 159892"] Building my second Huztl 361. Doing some port mapping preparatory to port and piston mods. Was very surprised that the upper transfer ports are about 1/3 covered by the piston at BDC. While plotting out piston mods, kind of realized the low transfer port location as it relates to the piston, means the entire load makes a 180 degree turn coming down off the inside top piston cavity, through the piston ports, and downward around the lower cylinder transfer port edge before traveling up to the upper transfer ports. Nearly 30º is spent with the piston close to or at BDC, and most of the fuel air mix will transfer with piston nearly or at BDC. Looks to me like lowering the side ports in the piston and raising the upper transfer ports will do more than anything else for the transfers. What am I missing? I know I'm just learning this stuff.
