Started after 18 months

Choke isnt stuck on is it?

Choke is fine and moves freely.
Cant see any air leaks.
The carbs are totally standard and i have not touched any settings, the only problem is the bike has not had a good run in 5 years and was last started 18 months ago.

All i have done is stripped the carbs, cleaned all the crystallized petrol out, they are gleaming inside.

Well if it starts and idles, let it run for 5 or 10 mins to warm up first if you havent already. Then try reving it up. I had that with mine when i first got it going after 18 months, but once it had warmed up it was fine. Luckily i didnt have crystalised petrol as i emptied the carbs before the bike was laid up.

I did let it idle for 10 minutes, then if i opened the throttle slowly it revved all the way up.

If i opened the throttle quickly, it died instantly.

If i have the choke slightly on, i can rev it up quickly.

I'm nearly at the point of giving up and sticking it at the back of the shed for another 18 months.

have you looked at the mixture screws to see if there ok ?
and cleaned them and the carbs ?
if it dont idle as it should its normaly the mixture so could be the mixture screws need cleaning , replaced or adjusting its normaly two and a quarter turns anti clockwise for standard

Dont mean to sound thick but am i right n thinking the mixture screw is item 2 in the fuel system manual (called the Pilot Screw)?

I have had all this apart to clean so maybe i have put it back in the wrong position.
