Hey....been working on this Martin I acquired a year ago....replaced water pump, coils, plugs, cables, points, condensers. Starts right up every time but seems to lack power. besides the low speed and high speed adjustments is there a throttle adjustment that I am not aware of. Ay ideas as to what could be causing this lack of power. Manual indicates bent prop...this is ok and low compression (not sure if this is the problem.....any ideas are welcome....thanks Victor
