Nzak · Dec 17, 2018

i rebuilt the carb because it was flooding.
it changed nothing still floods.
allis chalmers 170 zenith carb 13294
I replaced the needle and seat again because it was sticking still not helping gas is coming out of the manifold,
replaced all manifold gaskets and also used gasket maker to hold in place still comes out.
any help what could be wrong
next i was thinking to replace float.

is the float filling up with gas they get small leaks in them and get gas in them

Nzak · Dec 17, 2018

No there is not gas in the float but I adjusted it in the wrong place probably messed it up. Then tried adjust it again and i drop it. Dented it a bit.

dents wont hurt it as long as there isn't any holes in it check and make sure all the vent holes are open and not blocked with dirt if air holes in carb stop up it will cause it to flood out

I disassemble it completely soaked it in the 1 gallon can overnight. Bought carb cleaner sprayed it in all holes. Could it be possible that the main jet is bad or float not adjust correct. I'm disassemble it tonight again.

Get you a set of cutting torch tip files. find the one or ones that fit passage way holes in carb and make sure they are open. Just soaking doesn't always totally open passages.

you could of got a bad needle valve or seat

chaskaduo · Dec 18, 2018

I have been told if you have a rubber tip on the needle valve to tap it into the seat to kinda set it. Not fool proof but may help.

Put a q-tip in a drill and put some metal polish on the end of it and run it on the needle seat. Spray with cleaner afterwards. That has worked for me. As said above tap the needle if it is rubber tipped in the seat. Adjust the float as per specs. Hold the carb upside down and blow into the fuel inlet it should not let air in. Do the same right side up and air should go though. I think alot of us have had that problem.

Make sure the gasket is on the needle seat, and the right one.

Nzak · Dec 18, 2018

That's what i thought after doing research. Had a new one sent again still the same thing.

ever get carb fixed

Raptor44 · Dec 22, 2018

Mine did the same thing. Ditched the rubber tip needle valve and put the solid Steele one back in. Problem solved.

Nzak · Dec 22, 2018

Nope. Just got in with installing it again.
Tractor run good but gas is running down from manifold gaskets still. I'm thinking there something else wrong. Anyone ever have trouble with the main jet screw under the carburetor maybe that's letting to much gas in. Mine is really loose if I turn it in it will stall. This is not my first rebuilt 9 years ago I rebuilt the other tractor carburetor same model with no problems.

Nzak · Dec 22, 2018

Where can I get just the needle.

Nzak · Dec 22, 2018

Did that still same thing

Nzak · Dec 22, 2018

Next I'm taking the carburetor off my 1st 170 and installing it on this 170 tomorrow.
Then I will know for sure it is the carburetor.

(quoted from post at 02:20:19 01/03/19) Replaced the main jet asy still floods.

Any luck with your carb yet?

Nzak · Jan 11, 2019

Nope gave up. Now it drips fuel all the
time. And something else is wrong,will
not start. Message up firing order
battery goes dead because I keep trying
to start it. To cold to work outside.
