replacing a secondary jet?

<< < (2/2)

Well I got the replacement secondary jets (washers) and they are .010 larger than the originals.  I put them in along with the kit I got from Cliff and everything was running good until I got into the secondary's and the engine wouldn't idle back down to normal and was running very rich with tons of black exhaust coming out.  I found a donor carb and was able to get the jets out of it without damaging them by cutting the well area off the bottom and lightly punching them out.  Haven't got them installed yet but hoping that will solve the problem.

And the saga continues, got the jets in just fine and steaked them slightly with a sharp punch. While I had it apart I replaced the
.041 primary rods with .044's.  The carb now idles very nicely and has really nice power through the entire range of the primarys through all four
Gears.  The secondarys come on strong with no bog but they tend to stick slightly open .  I ground the base gasket back a bit
But apparently that wasn't the problem because it did the same thing again when I got it out again.  Anyway, I'm very happy with the way it runs
And idles and ill get the secondary thing figured out.
