spending £35 getting the cdi tested at this stage?

8's are fine and really better

same as bandit

ok thanks...general opinions are its a carb prob, not CDi as it starts an idles fine?
Strip and replace O rings at the weekend, any one know the jet settings fo a 73a sp/
cheers

Should have 95's or 110's in it something to that sort

Right....pulled the carbs apart to replace the O rings. The current rings look to still be in good condition (only got as far as the emulation tube/slide holder, carb top, float bowl 7.5mm and float bowl 5.5 O rings) so i haven't done the pilot jet screw yet. I'm reluctent to mess with the jet settings unless it is likely to me the problem.
The needles and tubes look in good condition and I think all the jets are clear as far as I can see.

So as the running is only bad when the throttle is open (fine on idle) does anyone have any ideas?

cheers

bit the bullet and did the whole O ring kits.......................and it lives!!!!!!!!!!!!!!!!!

Thanks for all the info and help guys

Nice one, these o-rings have a lot to answer for haven't they

They wrote a book and made a film about them my precious.
