She started !!:thumbsup2:

Then went up and up… to nearly 5K RPM on half choke.

New Plugs gapped

Valve clearances done.

Air screws out 1.5 std turns on each carb x 4

No leaks. (That I can see)

Float heights 99%

Throttle back set on butterfly

Correct slack on throttle cables.

Carb Sleeves set 0.6mm up from closed

Needle clip at mid position 3 of 5

Jets 2 years old ish – running fine.

The idle screw is backed out loose.

Started fine after a few turns after being apart for nearly a year. rough though.. so the plan was to do the timing. Boyer fitted.

At ~ 1000 its too erratic to see where the timing line is.

about a minute of running the revs rise to nearly 5 before I kill it.

but at this point the timing line is closer to TDC than F

Turned down the air by 0.5 turns

Still climbs way too high on its own to ~ 4K.

So.. I have it in my mind to lower the sleeves, which is a bit iffy as I can’t gauge them then from having them set at 0.6 ish.

Any pointers welcome – major grey area for me
