I ordered a TV cable mounting kit from Bowtie Overdrives to mount the TV cable from the 200R4 I installed in my Bird. The instructions are not that helpful given the linkage shown doesn't look much like that on my '68 Rochester Qjet. Hoping someone could post or send me some pics of a properly mounted TV cable on a Rochester.
Did you get the TV made EZ system from Bowtie? It really helps. Also, once you are a registered customer, the tech help from bowtie is great. Check the website. I put a 2004r in my bird with great results (but a holly carb)
The website doesn't cover the Rochester Qjet and they were closed today when I called. As my weekend is dedicated to being in my garage working on the bird, I was hoping I could get some advice this weekend.
Here some info I have saved: -------------------------------------------
SUBJECT: Proper installation of the throttle valve cable on after-market carburetors or fuel injections. This information applies to all 700R4, 4L60 and 200-4R transmissions.
#1. The button that the cable hooks to at the carburetor or throttle body must have a 1 and 3/32-inch radius from the center of the throttle shaft to the center of the button the cable hooks to.
#2. Looking at the throttle shaft lever from the left side at idle position, 33% of the throttle lever total travel must be to the rear of the throttle shaft centerline. And at wide-open throttle, 67% to the front of the throttle shaft centerline. This will be about ½-inch to the rear and 1 inch to the front of the throttle shaft centerline.
#3 The throttle valve cable must be hooked up in this manner so the pressure will rise faster off idle and slow down at heavy throttle. If the pressure cable is pulled in a more even manner the pressure will be too low at light throttle. Failure to hook-up the throttle cable in this way will burn the three-four clutch pack up fast.
#4 The throttle valve cable controls transmission pressure. Adjusting this cable is the most important step when installing a 700R4, 4L60 or 200-4R transmission.
#5 The final step is to adjust the throttle valve cable. The cable must be adjusted so it is pulled fully out at wide-open throttle. To make sure disconnect the cable, hold the throttle wide open with your left hand, pull the cable fully out with your right hand and see if the cable end lines up with the button on the throttle lever.
#6 Do not attempt to adjust the shift timing with the throttle valve cable. The shift timing is controlled by the governor springs. For higher shift points at wide-open throttle, install lighter springs. For lower shift points at wide-open throttle, install stronger springs.
#7 You can get a cable button off of a junk GM vehicle and weld it to your throttle valve lever. We sell a cable correction kit for Holly and Edelbrock carburetors.
#8 Sometimes on a newly rebuilt 700R4 or 200-4R transmission, it may not make the 3-4 shift when first installed. A stuck valve, trash in the fluid or an air pocket, usually causes this. Raise the rear wheels off the ground, place the transmission in overdrive position. Run the speedometer as high as 100 miles per hour, pop the throttle on and off and see if you can force a 3-4 shift. Once it makes the first 3-4 shift, work the shift lever back and forth between drive and overdrive until the 3-4 shift works correctly.

Thanks Don. Between the instructions I got from Bowtie and your instructions, I think I can figure the settings out once everything is mounted. Are the pics you provided of a Rochester from a '68? My linkage is still a bit different from this. Is the blue bracket something you fashioned yourself?
The instructions I got from Don at the Transmission Center website several years ago when I was putting in my OD. The bracket was one I had laying around, no telling what its from. The pics are on my 68 Bird. The Qjet is a mid 70's, not sure exactly without looking.
