Honda-SOHC

Looking at the clutch on my K3 which is the one with the thicker Plate B steel plate.   There is a shim behind the circlip on the mainshaft but should there be a spacer between the clutch outer basket and the inner centre/collar?   Also for the life of me I can't get my head round how this particular clutch operates to separate the plates.   Does anyone have any sort of schematic operating diagram?

Simple question, should the hole in the idle jet be clear its full length?  Trying to work out if its blocked or correct.

I have always wondered if theold tube could be removed, the hole tapped and generic tube tapped to suit then sealed in, a lot of work if you can get another bowl!
What bike and which carb so when i get back from holiday in a couple of weeks i can look in my scrap box

550 K3 PD46 Carb.

Yes, that just popped int my head on a dog walk, worth a try

OK, found some instructions for installation on t-web 

Undo the centre small nut, take off the big nut on end of crank  ..... now where is the red spot located on the aluminium pulse trigger wheel  ?

That spot should be aligned with the "1 & 4" marks of the Honda advance and retard mech. If that's opposite (next to 1&2) then it'll do what it's doing now, that's firing the setup at 180 degree away from intended operation.

I was viewing the manual/instructions for install on the SOHC USA site for reference.

Yes the red spot is correctly aligned.   I've gone through the installation again today and think I've cracked it through some very careful movement of the electronic board and a combination of completing a full cycle once the LED is lit and positioning with the power off.   But it now lights in line with the F1,4 mark and extinguishes after the F 2,3 mark which should be correct.   However, in this position there is almost no adjustment left in the bottom right slot on the PCB.

Unfortunately, I can't try a start as I've taken the carbs off to sort a leaky float valve.

Thanks again for all your help and suggestions.

Here's a pic of the TEC advancer. Note that the tiny mark in the rim (in white rectangular) should oppose the hole (dito).

Yes, the orientation of the rotor is as the picture.

Advancer has not been apart, blue points on the left, yellow points on the right.   Blue coil to 1 and 4 plugs.

I'm assuming it is the correct unit as I checked over the phone when confirming my order.
