hey all for the reps.... finally got around to my sons and we can safely say it not electrical, plugs all good (new) checked for spark..... leeds coils ignition box all good.... cleaned out the carb
just because, fuel filter air filter bla bla.
what i found after cranking it over...... still only one cylinder (rear) firing and absolutely nothing from the front, if i had placed a feather in the end of the pipe it wouldnt have got blown out. no pumping of anything.
so i guess that means svs
now how the f#%k do i fix that, cant get seafoam here but im sure there will be something similar, like to try something easy before pulling anything apart
did find Marvel Mystery Oil.... but it would take too long to ship....
it did backfire out through the carb a few times.....
