The float height is adjusted by moving the seat - it is an amal after all ....

If you put the amal back on, make sure the float level is correct before doing anything else. I take it your use a slow throttle ?

The woodruff key is purely an aid to locating the flywheel correctly and plays no part thereafter.

Just out of curiosity, would you fit the seals springs out or springs in ?

Could be an air leak, check everything. Also look for split or cracked hoses.

What he said ^^ Height wise, somewhere if you take a horizontal line from the bottom of the gearbox sprocket window.

Life's to short ?

Just leave yourself enough adjustment for when you eventually discover your wrong.

There are many tank sealants ,https://www.caswelleurope.co.uk/ethanol-proof-fuel-tank-sealer/ How successful they would be on an old dirty tank is debatable. Personally, I would go for an alloy liner using the original as a cover.

Modern petrol will damage fiberglass tanks. Ignition https://www.electrexworld.co.uk/acatalog/STK-247.html

Just set the stops so the forks don't damage the tank or whatever, you can't have too much lock.

You can replace the outer seal and o ring easily, think they are all the same but best to check https://www.motoswm.co.uk/shop/swm-rotax-kickstart-clutch-cover-oil-seal-kit/ There is another o ring on the other end of the shaft, which requires casings to be split to replace.

As above, refit it and tension as per spec. Then looking at the rear sprocket, at the point furthest back, pull it away from the sprocket, if there is any significance movement it probably needs replacing. What condition are you sprockets in ?

Current thinking is the forward edge of footrests should be lower by a few mm.

Most regs / definitions for eligibility state max 35mm, except jumbo swm's. It's what's inside that counts !

RAL 3000 ?

Have a look here https://www.motoswm.co.uk/tech/ What info do you need ?

And a (un)fair proportion of pre65 and twin shock riders !

Definition of revised - reconsidered and amended ! Does that mean changed back to how it used to be before it was improved ?

Is the plug wet after you have kicked it 6 -10 times ?

Tube type irc is a very good all round tyre, grips well even when worn. Haven't used Mitch in years but sure its as good, supposedly better in mud.

It's a space time continuum question, you do know that ??
