Edit Update: FIXED!

TV cable location was 1" forward from previous bracket.

Shortened cable and re-adjusted. Works fine now!

Phew!!
--------------------------------------------------------------------------------------------

I changed my throttle bracket from this home made one:



To a standard GM bracket.

Throttle works perfect.

Hooked up the TV cable, knowing I would have to re-adjust it.

Pushed the 'D' button and slid the adjuster all the way in.

Opened the throttle all the way.. no click.

So I pushed the button again and pulled the adjuster out 2 clicks.

Took the car down the road and it shifted hard and wouldn't shift into 4th
until I hit above 55. And then only when I let off the gas.

To me that meant the adjuster was still in too far, so I pulled it out 2 more 'clicks' with the same result.

3rd shifted above 45 and 4th above 55.

So decided to do it differently.

I pushed the adjuster all the way in. Opened the throttle all the way and pushed the 'D' button and the adjuster slid out and stopped.

Checked the cable tension, and all seemed to be well..

Took it down the road and the shifts were too soft. Kept stopping along the road and pushing the adjuster in 1 or 2 clicks at a time, but no change.

Finally pushed it all the way back in and still shifting too 'soft'.

Took the cable off the carb. Drove down the road and the shifting is still too soft.
Is my tranny toast? Or am I just doing something wrong.

BTW: I didn't 'horse' it down the road, but just drove normal.

thats an interesting choice for a carb, have it sittin on a shelf?

Its an Edelbrock 4bbl.

A modern day Carter carb.

Made by Weber carbs.

They are super easy to tune & dial in with the right metering rods, Jets, & power piston springs.

Give very good street & strip performance with knowledge & experience.

I have made thousands on side for the last 20 years tuning those carbs for people.

Part of the tuning trick is dialing in a distribuator advance curve that works on the street day to day in all driving conditions with available pump gas & gives Max performance.

Came with the car.

That's the PO's homemade 'bracket'.

Nothing but quality!!

Keystring

Yep. Super easy to dial in.

I adjusted the mixture screw settings recommended by Edelbrock, and then made another quarter turn in to lean it out slightly. Retarded the timing a bit and set the curb idle at 1000 and the in-gear idle sits at 650-700.

I haven't done a real good check of the gas mileage, but I drive 60 miles a day, to work and back, and I can easily go 2 days on 5 gals ($20.00 worth)of gas.

So I'm guessing about 23 to 25 mpg with normal driving.

Not too shabby for a 'carb'.

87 vette 81 big girl

No, not too shabby.

I am 41 years old & still like carbs too.
You & I likely are the only ones on C4 that will speak up & say so.

Carbs won't work too hot with twin turbos or 28psi of Vortech YSi centrifugal supercharger boost..............
but they are dirt cheap to set up & go play on the street & strip with.
And surprise many EFI owners with there stellar performance when you nail the gas fast & hard.

Other guy spent $3 to $5K.
You spent around $300 to $1K.

LOL

didnt say it was wrong , just interesting

Keystring

I don't think I said you did.

Just pointed out the 'quality' work of the PO.

He had other 'quality' addons as well.

For instance:

His wonderful 'door molding' trim!



Or the wonderfully done Console 'molding' enhancement.



And, of course, who wouldn't want the eye grabbing added side molding?



There were a few more 'enhancements' that were removed as well.

Needless to say. His 'mods' are gone!
