Carburetor
A few weeks ago I had to get a new carb so I just got a replacement for my old one (a generic Holley 1850). The guy that did it shortened the choke cable a little bit, on the old one it wouldn't open quite all the way so he put a spring on it to open it once you pushed it back in. On the new one you literally can't shut it by pulling the cable in the cab, you have to open the hood and push it shut. So I took the spring off and all it did was make it easy to shut but once it was shut it wouldn't open at all. I've tried different sized springs (ones I had left over from when I had to replace the throttle spring) but that didn't help. The cable isn't bunched up anywhere and I'm completely stuck on how to get it to open and shut smoothly.

Re: Carburetor
Is the cable housing secured on both ends?
With the cable disconnected from the carb, is the total fore-to-aft cable movement enough to move the choke lever from fully closed to fully open? Sounds to me like either the housing isn't secured on both ends, or the cable is binding in the housing. |

Re: Carburetor
So it's off when pushed in?choked when pulled out?
your control sounds backwards Its best not to have the control sit flush to the dash,when pushed in/off. |
Re: Carburetor
does it help if you hold the throttle down a 1/4 when you set the choke??

Re: Carburetor
The choke plate is shut when you pull the cable out, the choke plate is open when you push it in, so choked when out regular when in

Re: Carburetor
I like the manual choke too!
When you get the new parts you should adjust your cable so the outer sheath is clamped closer to the clamp. I always set my manual choke cables up so that when I pushed the knob in on the dash, the knob was about 1/8 inch from contact on the dash. That way I always knew it was pushed in all the way. One other thing I did on holley carbs was remove the little black button that pops in the hole on the choke cam. You'll see it when you put the new parts on. That way my choke moved freely from open to closed. I always had the habit of checking my choke was pushed in so never had a problem with the choke closing on me with the button removed. |

Re: Carburetor
The button is there to keep the choke wide open. I removed it to make the action of the choke smoother. It always seemed to hang up a bit when I pulled on the choke.
I lived in a cold climate then. Anything to make the choke action smoother when firing up the old beast at 10*F helped. |
