4l0 misfire after rebuild

[1260dave]

Just restored my 4l0 and tried to start it and its misfiring, It will not rev and cuts out after a few seconds, When you try to rev it it bogs down and cuts out, Its also not firing on the right hand cylinder.
I've fitted many new parts (new to this bike but second hand parts) like the stator, rectifier, coil, I've also fitted a set of pwk 28 carbs, So i've still got to sort the jetting out.
I'm thinking this is electrical,the spark doesn't look to strong to me.
What do you guys think
I never had the bike running before i stripped it

1st thing i wud do is try a new set plugs,,,are u getting good spark from the plugs?cud be a number of things so its a matter of ilimination!

If you haven't cleaned the carbs out then that could be a cause.
If the pilots are blocked it runs like a pig

I wouldn't have thought that would cause back firing

sorted it folks, just changed the reg/rec, wasn't that, changed the cdi, hey presto sorted, i'm gonna have to rip some wadding out of the stingers, it aint loud enough
cheers for your input chaps
