Will be interesting to here your thoughts as this is something I'm planning on doing.
Also can now see i was wrong about the jacking bolt not reaching, didn't realise there is a square bit on the top of the threaded part, sorry!
Took it out for a short drive today. WOW! That is such an immediate improvement in positive feel to the clutch and throttle it is amazing.
I had never driven a cog belted machine before the Morgan and thought that was what the belt felt like; boy was i wrong! The belt is solid and all the squishy feeling was coming from the NVH. The clutch acts more like a normal i would find in the John Cooper Works mini. What a must do improvement.
As a side note, it made the fuel response feel more immediate.
