i have started the process of changing jets and doing test runs per @sofakingdom guide from 2007. While under the hood I decided to record how the throttle blades in the carb reacted while using the accelerator pedal as I have at least 1” of slop travel before the cable gets engaged. The result in the video I posted is secondaries that are lucky if they open 50%.
I also posted a 0-60 run from my GoPro for reference before any jetting or tuning took place.

I will continue to post to the thread as I make changes and record more 0-60 runs for comparison.

 

Couldn't get videos to attach the original post so have posted links to them on my Youtube
0-60 I will link the throttle blade video when it is done uploading.

 

Here's the link to the video of how far the throttle blades on my carb are currently opening

 

Sounds like you need a different bracket for the throttle cable.

It's also likely you need to get your TV cable (to the transmission) sorted out. Otherwise you can smoke the transmission pretty quick.
