Mike,

Great diagram of the header setup. Question... will a standard carb(i.e. 2 stroke) have problems with running rich in midrange and loading at idle with a check valve setup? Also with a check valve there will be pressure in the tank all the time. This would cause fuel to run out the carb after shut down. Use a regulator of some kind?

I have run header tanks before but with just muffler pressure feeding the main tank and it works good as long as the main tank is also near the carb centerline. Get the main tank higher or lower by too much and there gets to be an inertia issue feeding the hopper tank and starving the carb on hard g manuvers. Best way in most cases is to use a pump. The header tank will help eliminate air in the system a trick the jet guys use.
