I am thinking that it may be running rich when the secondaries open, and then once the engine builds enough RPM the mixture leans out a bit and it makes more power. So, I was thinking that it likely needs a spring kit to tweak the vacuum secondary spring to a stiffer one? Anyone have any other ideas why it would have no mid range power at WOT but pulls okay at the upper end?
It also has a TH350 transmission (not sure if it's stock to the car)? I noticed the kick down cable seems kind of cobble together with a bracket that doesn't line-up properly. It appears to be a TV style cable from a TH700-R4/TH200/TH2004R, with the push button and the ratcheting action. I adjusted the cable by putting the carb to WOT, but not sure if this style will work okay with a TH350. It seems to kick down okay though.
Any help is appreciated.
