Weak spark
Weak spark
I have a 75 440 t/t and it runs ok when it is at an idle some what but as soon as i give it Throttle it starts to run week like it is only running on 1 cyl it starts to bog down i can pull a plug wire and it won't make no diff and it don't always matter witch one i pull. The spark on my 340 t/t is a lot better I can turn the clutch by hand and get a better spark nice and bright, could this be a week cdi box.
