My 390 is in a very bad mood at the moment. At no gas she runs nice but when I give her a little gas she dies, and then when I give her full throttle she pulls but misses a lot and shoots in the pipes. Have checked sparks and cables and they seems to work.
Hope you people understand my writing.

They are changed to something called "Ignitor" Think it cant be adjustable. Some kind of electronic thing.

Hmmm, definitely sounds like an ignition problem. Check inside the distributor cap for anything funky...things like carbon tracks (look like cracks), center button worn way down, loose pointer on the rotor, etc.
Also, make sure there's no play on the magnetic pickup beneath the rotor. It should rotate left to right, just no side-to-side motion.
Make sure there's no carbon tracks on the coil, from the tower (where coil wire plugs in) to the coil case or to the negative coil terminal.

If it starts to rain, they'll tax the splash.
If you want to fish, they'll tax the bass.
If you plant a yard, they'll tax the grass.
If you don't play nice, they'll fine your *$#!

Have checked it and it lookes ok. But the plate under the Ignitor feels maybe a little bit hard to move but dont know exactly how it should feel.Johnny Canuck wrote:Have you checked to see if your vacuum advance hose is leaking, broken or right off?
Vacuum hose from the carb to the distributor.

I shall check that but myself I had a feeling before that the fuelpump maybe were getting bad.Slick Fan wrote:Hmmm, definitely sounds like an ignition problem.

You might have a bad accelerator pump, and by now you most likely have a bad economizer valve with the backfiring.
