YES
The white ones "if they are original General Pump Parts" are made out of a material that handles higher temperatures. Kit 101 I think. The only difference is the material in which they are made of!
If the engine is cold this is normal. If the engine is warmed up then the pressure is too high or your air filter is dirty or the tip is too small or plugged up.
Open up the unloader and look for peices of that broken valve stuck inside of it.
i found out why the motor would bog down when the trigger was pulled,one of the rocker arms on a 20hp v twin honda engine came loose,my local dealer fixed it under warranty.
I was thinking pumps not engines. Just had one like that a couple of days ago but I didn't even think about that as the problem on yours because the engine would just throw out oil into the carb and choke it's self off, so it was easy to see the motor needed work.
