The thing with the primer is that the fuel has to go through a "pump" or a smaler piece of pipe before it gets out into the fuel line. Now, with a bi engine .25+ the "resistance in the primer is too big so the engine does not get enough fuel, ergo does not go as great as it would with a normal tank. The Sav 25 tank also has a rear pickup that feeds the engine with fuel even in steep hils og fast accelerations. The way a get fuel through the line, when my truck has been standing still for a while, is that i put my finger in front og the pipe outlet and eighter pull the cord a couple of times og use the rotostart for 1-2 sec.
