I'm at my wit's end with this motor.The motor will start right away on high idle i let it warm up for 5 min.
Its smoking like the marlboro man at a poker game. It sparking on all 4,
138 psi on all four ,I set the static timing at 30 degrees by taking the plugs out and in gear cranking at wot its flashing on the middle of the 3 lines on the flywheel to the marker point.
I pumped out the old gas and put fresh mix in it,cleaned carbs set the floats even with the carb body when its upside down and level. The mix screws looks fine I cleaned both carbs ,inspected the mix screw seat with a flash light.The fuel pump diaphram was in poor condition flakeing blistering but no hole so I replaced it along with all the gaskits . The screen on the pump body was filled with cowl insulation foam but not clogged . I put new coil packs on becase the wires looked old and brittle . the primer bulb is rock solid.The Isssue is when I go towards neutral (after warm up 1200 rpms im guessing as there no tach on the boat) on the controll and it gets under 1000 rpms she cuts out and she will not start in neutal at all, Sounds like shes starving for fuel in the neutral position give the forward idle a push forward she starts and runs great top end sounds great. I synced the carbs and linkages.Is there a timing advance setting for the neutral position on the control some where and Im missing it or somthing .It seems like a very basic motor and cant belive I cant figure it out, I can fix anthing but I am stumped here HELP ME PLEASE as Im going to burry it in mybackyard shortly.
Thank's
