Rejetting for reeds and head temp

[m in sc]

regular petcock and everything should flow fine. check for restrictions. my advice is: clamp off 1 line, take the other off, and put a long line on it. put line in a gallon jug, turn fuel on. watch the flow for about 2 mins. if it reduces over that 2 mins, you have a restriction somewhere .

Just performed that test and there was no fuel flow reduction over a 2 minute period. The only indication of flow reduction I got when the tank was near empty on reserve. The line that goes to the RH carb started flowing droplets while the line for the LH carb was still flowing albeit weakly. Although I'm not sure if this is any indication of my issues since I try to keep the tank filled above half. Interestingly when I testing the petcock one port at a time if I pulled off the plug off one of the fuel port with a hose on the other the open fuel port wouldn't spill any gas unless I hooked a fuel line back onto it.

you need to pinch one line off or cap it completely or it will pull air up through one. this can and will give incorrect results if you dont.  trust me on this.
