You can drop Tools an email and he can send you some pics if you want. Just click his name and you go to his profile and you can email from there.

Like Tools, I use a qtip as well.I'll usually wet the seat down with carb cleaner and then stick the qtip and and twist back and forth to get crap off. A wooden dowel would work I suppose but the issue would be getting the correct point on it to be sure you are getting the whole surface.

You might look into replacing the needles too. Get good rubber tipped ones again. I got some cheaper ones and then are OK but never fully seal. I can get a few drops of gas on the ground after a few hours. I never had that with the old honda needles.

With the accel pump, make sure that diaphragm has both ears opened up. Should be a hole in each one for proper function. Some only come with 1 ear open.

Do NOT get carb kits with round 0-rings for the float bowl. Those SUCK! I got those once, ONCE and never again. You have to glue down the o-ring to keep it in place. Screw that, get the formed ones and save yourself a headache any time you remove the bowls.

And finally, how far have you turned in the idle screw? OH OH OH!!! did you set the Fast Idle Cam?
When the choke is pulled, it opens the throttle a bit to increase rpm while warming up. If this is not adjusted, you need to keep a hand on the throttle till the engine warms up enough to stay running on its own.

And, float height is measured right from the side, at the middle of the float and should be 14-15mm. if I remember correctly, the clear tube test should put the level just below the top of the float bowl.
