Fouling spark plugs su carbs

[Datonedatsun]

Pic 2&4 are front carb, 1&3 rear

[240260280]

the front nozzle needs to be lowered and the rear raised. Adjust nozzle height by turning Idle Adjust nut  (6)  (knurled knob)

[Datonedatsun]

Is there a specific height recommended? 

[240260280]

to set both nozzle heights, turn Idle Adjusting Nut all the way up then turn it down 3 full turns.

Not sure 3 turns was enough looks pretty short here's some photos, these nozzles seen a bit different than my other ones

Great photos!

Now it looks the same for front and rear. (needle tip showing amount is same)

Try it. If the plugs need more colour, lower the nozzles 1/2 turn (3.5).  If it runs too rich, raise the nozzles 1/2 turn (2.5).

Alright so I drained the fuel cleaned the spark plugs and started it, got a horrible back fire and dies when given throttle, I tried turning up the fuel and it didnt seem to help? Out of curiosity when the needle goes lower that is more fuel correct?

Lowering the nozzle adds more fuel.

The next thing to check is fuel level in  the bowls and correct needle valve functioning.
