Two things will improve the drivabilty immensly. 1 – install a Pertronics ignition to replace the points and condenser. 2- replace the 2bl carb and manifold with the F4B manifold and Edelbrock 4bl carb with electric choke. I did those shortly after I bought my Tiger and the engine response was fantastic. With the 2bl the engine would stop pulling after 3000rpm. With the 4bl the engine pulled all the way to the redline. The Pertronics eliminates having to set the points gap which always seems to change no matter how well you did it in the first place. Plus you don’t get points bounce in the upper rpm range.
