Setting up carbs to start

if its not even coughing on easy start then Id also be starting to look elsewhere. I.e, you say its got good spark but are the coil packs wired correctly? its possible to have the low tension side to the coils wired backwards and that would spark the plugs but at the wrong time.

Also have you tried a compression check?

Good morning all, firstly I'd like to thank you all for your help. I've tried a few things to no avail. Yesterday I decided to completely strip the carbs down and clean and inspect them. I bought them from someone on a forum in good faith and in the understanding they were from a good running bike (or so id been told) so I didn't really inspect them closely (my mistake). Once i had them separated and stripped a few things immediately jumped out at me, the main jets were different to factory along with the needle valves and there was a copper coloured pipe missing from carb 2 that runs from the choke slider down to the bowl along with the internals having a lot of gunk in them Luckily I was able to steal the pipe from my old carbs and I've cleaned and rebuilt everything with a rebuild kit and copious amounts of carb cleaner. I've not finished yet but I'm on to carb three. Fingers crossed please!

OK - maybe post some pics when you can - just to make sure we're talking the same language.

Float bowls exist at atmospheric pressure so that won't hurt anything. It's what pushes the fuel up into the choke anyway so it's actually quite necessary.

looking like another tick towards VJ's carb theory; 90% of carb problems are because somebody fucked with something they shouldn't have. The previous owner of your carbs in this case.

Hi all, so i tried a little easy start and it fired up and ran for a few seconds before it burnt it off and cut out again. Pretty much assuming that proves its a fuelling issue.
Ive then removed the carbs again, stripped them down and boiled them in a lemon juice/water mix (saw it recommended by loads of people as a good cleaner for them) and the amount of crap that came out from the places that cant be seen was insane! All passages have been then rinsed, sprayed with carb cleaner and then blown through with air along with the jets. They are now immaculate to look at at least! I've once again set them to the settings in the manual and am looking to get them fitted this weekend. Fingers crossed!
