As Lynx has said valve clearances are important.
Check the fuel mixture as well. I run mine a bit rich, just enough to crackle on the overrun. I did use a colortune to begin with but after a while I learnt to do it by ear. I carried a small screwdriver and made tiny adjustments to the mixture over the space of a month to arrive at my current settings.
Float height and carb cable condition can be a factor too.
When it all comes together the effect is pretty magical. I've not managed to get a garage to do a decent job of tuning engines, they get in the ballpark but you need to ride it and get a feel for different temperatures before you find a good compromise.

Tested the fuel tap, that was fine.
Fitted a fuel reservoir to the carbs and balanced them okay though they were tricky and the left middle carb wouldn't match up with the other three no matter what we did.
So we thought it was a lost cause, however it was revving much better and no sight or sound of the dramas in that video I previously posted..
So I took it for a test ride and it rode absolutely fine for the 15 mins I was out for.
Shocked is an understatement. It's not that smooth and needs a little "something" to smooth it out but I have no idea what. I may take it to a garage to sort.
Overall, It runs and pulls fine and I wasn't expecting it to run like it is.
Great evening!
