malossi 210 and phbh 28 set up

As you are going to the trouble to get the timing really spot on, you should first check that the timing marks on the flywheel cover are correct. Plus or minus a degree or two is very normal.
Use a degree wheel to mark TDC, 18 degrees forward from the original timing mark on the cover. Then Check that your piston TDC and flywheel indicator is where the TDC mark on the cover is. Or just make your own new marks, whatever is easier for you

On the other point, yours does seem to be a little slow in 4th gear....for a tuned 210! Can you remind me what gear cogs, clutch and primary drive you are running?

NEVER go by the timing marks on the flywheel cover !!! ....you can not guarantee that they are correct the marks on the cases are a little more accurate BUT again not 100% and with a 2 stroke and if its been modified !!!!
You can however find TDC by using an old spark plug remove the inners and put a nut and bolt through it so there will be some thread showing the other side ....screw the plug into the cylinder ( I use 10mm head 6mm thread)
Then carefully move the flywheel clockwise until the flywheel stops
Mark the flywheel and casing
Do the same anticlockwise until the same happens
Mark the casing..
Then using a degree disc you can work TDC between the 2 marks.....from there and with a degree disc OR strobe light you will be able to accurately measure the timing
OR of course you can use a dial gauge...you will have to remove the cylinder head though !!!
Im sure there has been a thread on here at some point
Hope this helps
If your still unsure give Al diablo a call hes built and set up plenty ....
Good luck fella.....sounds though you are struggling with the speed and set up it certainly should kicking out a lot more power/speed....

Just my tuppence re timing !!
I've found if you're using the piaggio crank, the timing matches up with the marks on flywheel and flywheel cover perfectly!! ( Just did my own and double checked it with degree disc and positive stop method and strobe).
It's when we utilise aftermarket cranks this can alter things somewhat.
Always best to double check though

just to update on where im at,

i finally got a stobe off someone to strobe it up, im going to put in the carb some ball park jetting as my engine is similar to someone else i know,

i fitted a new pinasco crank so

i have used the dial guage method to work out TDC with new marks and i read on scooter help, that 18 degrees is 1.75mm back on the dial, so i have marked that out

will fire it up tomorrow and see how i get on, iv already filed the slots a bit on the stator plate, just in-case it needs more adjustment,
