so my sohc zc is missfiring eversince i rebuilt it, i've replaced plug wires, dizzy cap and dizzy rotor and new spark plugs...two sets actually one is ngk v power correctly gapped and the other set are densos.

the engine is still missfiring and the other day i was messing with ignition timing by moving the dizzy back in forth i noticed this for the first time that it sparked between the top bolt that holds the dizzy still...i dont think thats supposed to happen...what do you guys think??


i am thinking that the spark is grounding there and there isnt enough spark sent to the spark plug to fully ignite all the air fuel mixture in the cylinder? or am i wrong?? i am desperate for help now...ahhhhhhhhhhh!! help.

Near the distributor ? I would say its a bad cap or rotor. Check the cap for cracks.

 

brand new cap brand new rotor any more ideas?? its arching between the top mount of the head and the dizzy whenever i slide it.

Yeah take it off an inspect it, I don't care if they're brand new, caps can break if someone drops it.

 

Possibly sand down all your grounds, the dist grounds it self through the case, so it could be a grounding issue, any way to get a short video or anything?

 

uh i'll try to get a vid but i'll have to put the thing back together and make it happen again...cap looks good dude...no cracks no tracks.

 

While you have the cap off have a look and make sure nothings shorting out on the distributor body.

 

how would i be able to tell if anything is shorting out?

 

look for bare wires touching the dist body, black spots, evidence of blue smoke escaping!

 

the dizzy grounds through the case if you had the bolts loose then guess what, Shitty ground.
