I almost hate to tell you what i wound up having to do with my autolite 1100, but here goes anyway
symtems sound the same..lean surge rough idle, ok under power.
I found many problems with my 223 i6 after driving it all winter long in the harshest conditions the lower 48 states have to offer..but on a 6 block trip home from the school, the night mare began.
I had to retorque the intake and exhaust manifold, which didnt help.
Then opened the distributer to find the vaccume advance never worked since i bought it, the plate was frozen solid. I used 3/1 oil and worked it back and forth and on my 6th day of efforts, it finally got very free and worked perfectly. I removed the vacume line from carb to the dist., sprayed cleaner in it and compressed air...removed a bunch of debree, checked it for leaks, none. I removed the vacumme advance and checked it for leaks, none. Repaced the points, Rotor, and cap, no help. Timed it, wasnt off and didnt help. Installed new kit on the carb, no help even after atleast 3 hours of tedious cleaning and 2 cans of compressed carb cleaner and a half gallon of paint thinner. Adjusted float bowl from 1 3/16 to 1" exactly, no difference. Tryed every combination of carb adjustments known to modern man, no changes.
Finally after 6 days of working out in 11 degree weather and absolutly no difference or solutions, i did what was NOT recommended. I uncovered the float bowl and with compressed air and my fingers over the 3 balls to prevent blowing them out in the yard...i gave it allmighty hell with the compressor...then i removed the float and check valve and blew the crap out of the float bowl assembly. I reassembled the top and left the float bowl adjusted to 1", hooked up the fuel and linkage...the car has never run so good or so strong...absolutly smooth idle and can pick any idle speed i want all the way down to 250 rpm b4 it seems like it might stall.
This job was completed at 3:10 today, april 10th 2007. Took me 6 days to fix it. Ive rebuilt john deere combines in less time than that out in the field.
umm don't blow to hard on the hole that goes down to your acelerator pump, and use caution on all the holes, but ultimatly...this did in fact make my car work better than it ever has since i bought it in january over a year ago.
