Tools of the trade

The mix adjusters were set twixed 1-3/4 and 2-1/2 turns from bottom. Still w factory plastic caps. 8)



Thank goodness. Not too bad at all.



W heat gun and penetrant they came apart really nice.



Brass, tops and bowls soaking in Chem dip, stirring around a few times to help remove trapped air.





Bodies in Heated Ultrasonic w Pinesol, water rinse, compressed air, carb cleaner, compressed air then penetrant.

Just an fyi if you really feel frisky:

There are throttle shaft seals...




On 1 and 4, they are felt. 2 and 3 are rubber.

The choke also has felt seals.

Im not going that deep...yet. Hopefully the sonic wonder has done its job.

All the brass is gonna soak while I have lunch and a nap. 8)

Brass and Bowls came out of the chem dip as good as I knew it would.

So just for interest, finishing them off in the ultrasonic machine.

Curious to see how it handles the stuck on bits of gaskets.

Mines 15 liter $150.00 on ebay. And they got a 22 ltr for $210.00

It works awesome, Temp heats up to 175F / 80C if you preheat.

Mine hit 122F in the 30 minutes it ran.

The sonic softened the gaskets but it to the Dremel to finish them,



Its just freaky to me, how they could possibly drill these in a mass production environment.

Ask Kiley about having to make an emulsion tube this weekend for Jason's XS, since it didn't have one in one of the carbs.

All but silent. Maybe like the same as a box fan running. Just a low buzzing hum in the background of Pandora.

Cleaned up nice and going to re-use all the original brass...except, of course the new float needles will go in, as the old springs are mushy.



MAYBE the float needle seats too. If I do use them I will try to polish the needle seats up nice.

Re: The Black Knight, HOORAY its CARB DAY!!!

I do have to use the new float needle seats.

There is a 1/10mm difference in O-ring groove diameter.

Probably Keihin use some bastard size and the new one uses off the shelf.
