Remove the screw, and put the o ring right on the end.

which should just leave the "slide holder/emulsion tube" O-rings to fit!

Almost there then bud!

thank you very much!
just been and changed those two, now I can carry on with the rest of them, shouldn't take long now I know what I'm doing!! then to work out the emulsion tube malarky is all about

3 down and one to go...
for those who have been following the story of my bike, you'll know it had a catastrophic engine failure ending in lots of tiny little bits of engine EVERYWHERE, apparently including inside one of the carbs!
Whats likely to be best? Bang some carb cleaner through it and clean it out best as possible and check the diaphragm isn't torn or anything?
what would people recommend.
Also still haven't changed any of the "emulsion tube" O-rings... mostly because I dont know what/where the emulsion tubes are! so any help on that would be nice!
Have taken lots of photos so far and will do a nice step by step write up of how to change the O-rings for future 1st timers like myself

Anyway pics of the debris inside the carb

if you have any debris in the carbs. i would be stripping them completely!!!
i mean completely!!!
last thing you want is the debris ending up in a fresh engine

What happened to your old engine?


As stripes Say's, best to completely strip them.

yeah, what happened to last engine for bits to fly everywhere bud??

i'd say looking at that its lost at least a valve. usually lose piston crown aswell

snapped cam chain whilst in the red! bad times!


and one of the pistons!


that one carb seems to be the only one with any crap in though, which is good!
