Cool ,Cheers.

I never went out the other day after all.
( put the bike in the garden & took the tank off , 3 saturdays ago now )
Thats as far as i got , and i just keep looking at it, then walking away.
Sick of keep taking carbs off ever so offen.

Finaly went out to it yesterday , (Sunday) .
Set up me little test petrol tank ( got it hanging up on a pole above the clocks ).
Started the bike up, with no air box on  ( just to see if i could see in the carbs , ) see if i could see anything going on.
Couldn't really see anything , so did the fizzal test on the down pipes.
No fizzal on #1 & #3
Ripped the carbs off, #1 had some wierd gel / goo in the float bowl .
Took out the float part , MJ , little black plug and the jet thing under it ( about 1cm long , pointy at 1 end ) , is this the pilot jet ? .
Took the top cap off , diaphragm & spring, piston valve with the needle in it .
Tried to take the emu.. white bit out by putting the MJ in a bit and taping it .
The Emu thing stayed put but the needle jet did pop out a little bit into the main middle chamber.
It doesn't want to come all the way out, and i dont want to pull on it too hard incase something brakes.
Proceeded to blast every thing with carb cleaner.
All nooks and crannys , holes and gaps.
Put it all back together.
Then the same for the other 3.
Carb #3 was same as #1
Carbs #2 & #4 were clean , and no little goo blobs.

Put the carbs back on and connect up me test tank.
I now got Fizzal on #1 ,2 & 4 , but not on #3 pipe.
I let it idle , and rev'd a little . #3 pipe gets hot, but dont fizzal on testing.

SO take the carbs off again ( dont disconnect all the cables and wires this time ) ,just flip them over.
Double check #3 again , pilot and main , float hight , every thing seams clear and correct.
Put them back on , but still no fizzal on #3.

Give up and cover it back up again.

* just a side note .

I find spraying a fine jet of water on the down pipes for the fizzal test, the quickest and easyest way to see if its working.
If it dont fizzal, theres something wrong .....

Cheers for reading .
