autolite 1100 carb question

i recently put a new accel pump in my 63 van with an autolite 1100 carb. i must have messed something up as now it only runs with choke on even when warm
i may have put one of the balls in the wrong place or?
also it was strange the original float height was around 1 1/2 inches and the spects call for 1 inch
setting to either doesnt change the fact that i need to keep choke on to keep it running now
any ideas
thanks

thanks for the help
no i havent been able to set the rpm because it will only stay running when held at a higher rpm with the choke on

what will spraying carb cleaner on it tell me?

thanks

Whether the housing is leaking at the seams. I had one that the top housing was warped and no matter what I did, I could not get it to seal up.

thanks for all the good information
yes it was running pretty good other than a flat spot in it and no squirt from the accel pump, that is why i took it apart to replace it. in the process i must have messed up someting
will try the carb cleaner today and take back apart and look to see if i have the correct check valves installed, i read you can tell from the size of the seats what balls go where

yes i am the problem
will look down the carb

thanks

I've redone mine about four times and still not there yet. It idles crappy and the choke is not adjusted right - or is dead but under power it works good so I'm reasonably happy.

Here are some good reads. Keep trying, keep reading.

Be careful with the carb cleaner. I have seen engines catch fire because of an errant spart

Finnicky buggars, these carbs! Good luck, Ken. I hope you figure it out.

Yes. I think it's as much user error as anything. But that's what it is supposed to do.

well had the carb apart about 10 times now checking things
cant figure out what i did wrong
was running pretty good before i decided to fix the accel pump

spraying carb cleaner in and around doesnt seem to make a big difference
what makes it run the best is to leave the choke on and/or cover the carb some with your hand to act as a choke.

cant get it to stay running at lower rpms so adjusting the mixture screw doesnt seem to change anything

any other ideas?

thanks

thanks for hanging in there with me
yes the spsrk valve is in, and the line is on and tight to the dist

if i keep the choke pretty closed it runs, or as i back off the choke if i choke it down with my hand it runs better

as i look down the carb when running i see fuel flowing
i did pull the line to the dist off to feel the vac and there wasnt much suction at the carb

i ran out of carb cleaner spraying it around but didnt notice much change spraying it anywhere

I remember from my tribulations with my 1100 that I had to pay very close attention to the metal balls and where they went and it was a function of automatic choke or manual trans or something. I really had to study the diagrams to ensure I had the right configuration. so many friggin parts.

thanks, i think that is where my probelm started as when i dumped the fuel out i lost the original balls, but have really studied up on them and there placement, and think i have tried every possible combination shoit of leaving them out. kit did come with ome small ball that i havent used
but i have measured the ports and dont think i have a small port in the carb
thanks

i think yu are right about fuel comming out of hi speed circuit as i look around the choke and see fuel when its running
i did have the mixture screw broken off in the carb and had to weld a nut on it to remove it, have a new one now. i will do that spray check on in the mixture hole and plug inside and look for spray in the main jet as you mention
is the metering valve the tall one with the long spring? maual says not to take it apart.
sad part is it was running fine other that no squirt from the acc pump other than a little flat spot even with a bd pump and stuck moxture screw
thanks

thanks all
problem fixed, was a vac leak at the base of the carb, the new gasket was a little thinner and even though the nuts were tight, they were stopping on the shoulders of the studs coming out of the manifold before they tightened the carb down

put the old thicker gasket back on and washers under the nuts and it ran great again
using a new can of carb cleaner helped me locate the leak as it allowed me to tip the can up and point the spray better, had a vac leak all around the base of the carb just a little so the spray in one spot didnt make big change but did start to make me suspicious after reading the above posts

THANKS to all for the help!!!

Since im almost on the same problem im just gonna ask here.
I bought a carb from ebay a while back ('bout a year ago) i finally got to it yesterday and noticed there are only 3 bbs on it. Is this right? I have seen the exploded views and some have 3 while some have 4. I have never tried the carb since it needs a good cleaning.
