You should use a fuel pump,strombergs like 2psi.when warm or hot starting do not touch the throttle,just bump the starter and when its right it will fire in less than a full turn.Stromberg float level is critical @15/32"..if the power valve leaks it will cause a hot hard start condition,its located below the accelerator pump plunger,its opened when the throttle opens half way by the accel pump plunger to continue add fuel after the pump is out of stroke.
