The motor is running really well and feels like it could pull a 5th gear on the freeway, but I am just wanting to modernise the old motor a little bit and get it running nice and efficiently.

My last big day on the road (mixed driving, but mostly highway) gave 13l/100km. I'm pretty happy with that.

Zeniths leak past the O ring on the top cover,you'll never get it right while it does.Get a larger dia O ring,you might need a few to get the right one and stick the top cover in the freezer overnight to strink it a frag and with a bit of vaso as a lube stick it together and try again.I found the zenith was the best carby on the 2.25 and the webber the worst.
