timing light only works on 1 cable

Hey Guys something wird is happening. i have e 13 b 4 port and the only cable that i can get a timinglight to work on is T2. it idles rough and the mixture is pretty rich. the plugs are also wet on the remaining 3 plugs. but how ever there is spark on all of them. but the engine will stal when removing cable on T2 ANd the rest hardly has any effect when remowing cable.
could this be bad plugs because of the very rich mixture.?

I have a 48 mm IDA weber. the dizzy is brand new and when i installed it i set the timing correct.



Best Regards Rasmus ANdersen Denmark. Parten my english

Have you verified you have spark on all spark plugs?

what is your ignition setup??? points dizzy or electronic dizzy... if you converted it to electronic, how did you do it...?

Also, the timing of the dizzy would not effect how much spark you get... but it will effect how well it will run.

it sounds like you have other problems like something isn't wired correctly or a bad coil???


*edit*... how wet are the plugs??? if they are dripping wet , they will not fire and you wont get the timing light to flash... to double check spark at the plug end of the plug wire... just place the plug wire without the spark plug about a centimeter from a grounded source
