I recently put a TM-32 on my AVL. I modified the stock throttle cable to fit, just takes a little time and soldering. Bend/curve in the cable is not a problem. The bell mouth in the intake side of the carb is huge, 58 mm if I remember correctly. At the local ACE Hardware I found a black rubber-ish flexible 2"X4" connector which fit the bell mouth real well. I glued a UNI foam filter to the end of the connector, very clean fit. I chose to enlarge "opening" on the edge of the side cover to avoid rubbing between the connector and sidecover. Foam filter sits behind the sidecover, only the black connector from the carb mouth is visible. Clean, efficient,functional, and affordable. There is more intake noise at idle, but it is a big air pump.
I'm in the process of installing the "S" cams from BW, and waiting for the snow to melt. Looking forward to hearing/learning more about port modifications from ACE. My JB Weld is ready!
