So put the now not sticking carb back onto A10 and thought I would check it without the standard air filter, It runs really bad spits back through the carb and keeps stalling.
question one
Could this really only be the stand air box not being fitted. I have not touched anything else honest.
question two
How the hell do you get the standard air box on. I can get it on without the rubber that joins it to the card, but then can not get the rubber on. It just will not go on with the rubber on the air box or on the carb. Do I really have to take the carb off and fit them together !!!!

It may help to smear the mouth of the rubber with silicone grease; available from plumbers merchants.

Thank you  GreyBeard
Unfortunately its not that close or rather it is (you will see what I mean)
When fitting without the rubber it is a very close sliding fit between the carb, ski slope and the battery box front bracket.  It will not even get close with the rubber on the airbox or on the carb. When in place without the rubber there is only about 3mm gap between airbox outllet and carb inlet so can not slide the rubber in between. I am considering cutting a piece of old inner tube the right width and then wrapping it around and glueing it. Bodge I know but I could at least then see if it runs any better.

I have a rubber that fits, it came out of an old washing machine I was dismantling (amazing how much seemingly useful stuff can be had) it is supple enough that it can be rolled back on it's self over the carb, allowing the filter to be fitted and then rolled back.

OK I think I'll stop right there ;)

Over one month has pass, I have been riding the A7 and have had three experts (never owned an A10) come around telling me how easy it is to fit the standard air filter, they all failed.
So I am making my new rubber connector when the RAC man from my road says what are you doing, I explain and as per the others he says it must be simple (he does not even know what an A10 is). Anyway he persuaded me to try one more time his way, it worked damik (new word thanks muskrat).
So here goes in case anyone else has similar troubles
Fit carb and air filter together off the bike using rubber connector, then put whole unit up to manifold and do up bolts holding carb to head (not to tight). Finally do up fixings that hold air filter to the battery strap and the ski slope engine plate cover.
She ran pretty poorly with the clean air filter but a little tinkering with the air screw solved that had a good road test so she’s back  *smile* *smile* *smile*
