[Roadsters] Datsun-roadsters Digest, Vol 9, Issue 46

[Steve]

I only briefly read these comments . Issues are usually always traced to :

1. Needle and seats stuck and your running on only one carb ,or

2. Brass float is sunk . These ALWAYS fail eventually. Engine will flood 
out on 2 cylinders and usually blow fuel out of overflow. Buy new 
plastic floats,the replacements Nissan came up with. Plastic with a 
metal cage on them. Or you convert to plastic 70 style like the Z uses 
and you have to get more parts to use them. They hang from cover.

3. Use Stabile as a precaution on fuel to help sticking Needles . If we 
could still get Groose jets,these problems would occur less.
