no where to attach choke pull off

[condohk69]

on my q jet there is no choke pull off & no where to attach one ,so it also doesn`t have the rod to operate the secondary air valves.  carb number is : 7042262 xd 2541

all advice greatly appreciated

sorry trying to get a decent pick to attach

im not familiar with that carb but it may be one that only has the rear choke and flap pull off. ill have to dig through my junk and see . I'm sure somebody on here has one of them .might have to wait for them to chime in . fwiw

thanks for the reply.from what i`ve worked out it`s off a 1971 pontiac 455 auto.

i`m having trouble getting my pics to re size for the site to accept them,once i work it out i`ll put some on here

[condohk69]

ok hopefully i`ve worked out the pic re sizing & this works

your picture doesnt show me what im looking for . look at the back left corner for a couple of screw holes. better yet post a picture of the back left

 That carburetor, I believe, came with a mechanical choke. Looks like someone added an electric choke. There was a bracket that attached to the side of the carb, that the choke pull-off slid into and attached. I would look for some photos of an original one (eBay, Google, etc.) and see how it goes. I am pretty sure that is how it went though.

do you have cliffs book? page 39 bottom right shows what ethan is talking about . i think thats what you should have . if it was mine and i was keeping the electric choke (which i think work perfect )i would customize the air horn and install a front choke pull off.with a little southern engineering( no pun intended to anybody )you could probably do it in an hour or so.fwiw

Those carbs do NOT convert easily to an electric choke, as you are finding out.

To do a complete the conversion, you will need ALL the choke parts from a 73-74 Pontiac carb, or 1970-74 Old's carb.

This includes a different choke housing, bracket, pull-off, link, and parts from the throttle shaft.

You will also have to drill two holes in the main casting to attach the bracket, and there is no "boss" for the bracket, so it doesn't sit flat on the main casting.

Not a good conversion even with all the correct parts, IMHO.......Cliff

thanks for the replies cliff & 429bbf.

this carb came as is with my car,which i am restoring.i have just put a new needle & seat & re set the float level to fix a flooding problem.

i really only need it to run in my new motor as i will be converting to straight lpg once that is done.

i have the choke set so it is starting easily,my main concern is will the secondary air valves work with out the choke pull off ? will the carb be ok to run the motor in with ?

many thanks
jason

The choke will not work correctly without a pull-off, it needs to be unloaded some on cold starts, or it will be too rich.

Yes, you need the pull-off and link to dampen the secondary opening or it will require too much spring pressure to keep it from stumbling when you go to full throttle....Cliff

ok thanks cliff,i thought that may be the case
