I need to rejet my carb. It runs better with the choke open part way and lots more power.

Right now I have the stock 1973 Fj40 carb with stock jets. I can boe out my existing jets, but before I do that, I wanted to see if anyone had larger than stock bore size jets that I could try first before drilling mine.

What numbers are on yours?

May have some spares here in Oakhurst. Like Poser said, What sizes are you running now?

 

[slickrock]

Went to get the numbers I had written down and my son used the paper for a drawing project. Can't read them anymore. Will check this weekend.

Gotta luv that! And when they're all grown up, we'll all wish that those are the biggest s that they give us!

did you see what size the extra set of jets that came with it are? (there in the 2 brass plugs in front of the carb,alot of people dont know their there. screw out the plugs and look in the end of them.)

Well there is one trivial thing I never knew.

 

[LAMBCRUSHER]

That's why you're on mud!. My old carb had a primary jet and a ?power valve jet? as the spares.

It must be an "F" thing, ya or na?
