ok did the decarb today and took out on the river ran fine at wot or close for 15min then all of a sudden sputter, miss ,sputter miss, so i pulled plugs and top 1 starting to build up carbon check spark to see if jumps 7/16 no spark top cylander am leaning towards that coil being faulty so far replaced other coil, powerpack,fuel filter,head gasket also decarb has cylinders withen 5 psi, I didn't think both coils would go at the same time. lol thanks
