been having problems with my motor.. haven't ran it in 2 yrs but I started it with the garden hose hooked up and ran fine... put it in the water and wouldn't stay running... went home and replaced plugs and runs great.. took it to the lake the following day and started great and ran good... put in reverse and did what it was supposed to do.. put in forward and pushed on the throttle and no power... just bogged down... found a burnt wire under the flywheel going to I assume the distributor magnet.. can anyone help me and give a approximate cost of the part and tell me what it is.... thanks randy
