I use a Sealey WC06 wheel chock with the bike facing forwards and tie downs from the handlebars to anchor poits in the van. None of the pictures of the WC06 on sites that sell it show that it comes with two plates that screw to the van floor so it will slot in & out, even the Sealey wesite doesn't show them.
I have got an Italian handbook for a 307 and the timing is 3mm btdc for that too. There will be timing marks that you can check with a strobe on the flyweel just to make sure.
You will probably struggle to get the seal out with the fork stantion in place. Bear in mind that if you damage the chrome while trying to remove the seal it will cost £156 and about 7 weeks lead time to fix it. Stripping the forks means you can flush out all of the accumulated gunge anyway.
Is the sleeve perfectly smooth where the seal contacts it? I don't think starting it with a split intake hose would damage the seal. You may have to split the cases to check the gasket is sealing.
Going back to your original question; I found a 300 user manual the other day, its in Italian but (using Google translate)the carb spec is:
Main jet 108
Pilot jet 45
Choke jet 70
Needle X5 (clip in 2nd groove)
Needle jet BN264
Slide 45
now here's the odd bit;
Air screw 1 turn out ( but the diagram in the manual shows a carb with a fuel pilot screw not an air pilot screw)
If you do actually have an air screw and not a fuel screw then 2 1/4 turns will be way out.
I have attached the manual because there is other useful stuff in it:
Does anyone have any information on a Fantic 201? Ideally a parts list and handbook, but failing that details of the primary drive ratio and gearbox ratios?
The stepped steel one goes in the LH side of the hub narrow end first (there sould be an oil seal that it fits in to). The long alloy one goes outside the steel one and the short alloy one goes outside the brake plate.
If you PM me your e-mail I can send you the parts list which shows exploded views of the whole bike.
There doesn't seem to be a great deal of information around for 300s. I had a 301 which is the model after the 300 and still a piston port 250 ( and I think may have the same top end as a late 300) and the standard carb settings from my black book (its actually blue but....) are:
Main - 102
Pilot - 45
Choke - 70
Needle - X5 (clip in 2nd groove from top - seem to remember it had to be in the 3rd groove to stop it pinking when opening the throttle, but it was a bit sh4gged)
Needle jet/emulsion tube - BN264
Needle valve - 200
Slide - 45
Pilot screw 2 1/4 turns out (as a starting point)
Float height 23.5 - 24.5
If you ring Bill Pye (01642 722378) he will tell you all you need to know.
Time is money in my business. Fact is with proper tools I could concieveably shag that clutch out in under 5 min.
Just how good is that wrench you have, lad? When was the last time it was tested and certified best of 5% accurate? May be one them Chineese imports for a tenner?

They came with mine, I was planning to make something similar so was pleasantly surprised when it arrived with them.
