Well guys it goes like this I have had everybody look at my 78 merc missfire a nd still no luck
so what i have done is tried the spark jump test while running the results are as follows number 2 is strong and has a good blue spark number one is also pretty good but number three is hopeless I swap the switchbox to coil feed wires and it swaps the spark from coil to coil then i swapped the trigger wires to the switchbox and it also swaps the fault eg number two has stuff all spark and number 3 has a huge spark
could it be a wire in the wrong place or is it the trigger as the engine has been apart a few times
this one has me
anyhelp would be great
from desperate lol
