Ct90 stalls out

[plagrone]

Okay, my 1969 ct90 has a very specific problem. It starts first kick, choke on, and I can quickly switch it off and it will idle. It will rev, but as soon as I put any load on it (try to move) it dies. It will get going if I leAve the choke on.

What is this indicative of?

I've bought a $25 carb on eBay to replace the old one but I'de have to fab a mounting plate.


Help!

I'd imagine it's either your idle jet too small or your mixture too lean

It's a stock size idle jet that I just got done cleaning (perhaps not thoroughly enough?) and a NOS intake and boots. My overflow on the carb is dripping gas constantly, so I can't really fuck with float height at the moment. Guess I'll play with tha needle. Shoulda thought of that.

 

[coyote13]

If your overflow is dripping constantly I'd think maybe go ahead and check that float height, no?

Man, I bought new floats, new gaskets, Orings, jets, new float needle and seat, rebuilt the petcock, everything.... Can't get the fucker to stop dripping fuel.

I haven't checked to see if it's the actual overflow tube itself that is cracked, but I will next time I split the carbs, which will probably be soon

Took the carb apart, cleaned, again. raised the needle to it's highest setting. It still acts up.

Any other potential culprits?
