Ive noticed they might be hard to read because I've shrunk them a bit.

[Norbie]

Thanks for that Omegaman.

For those who want to see the full-size pics, click here. Dial-up users beware, some of them are over 1mb.

Omegaman on page six before it talks about Mikunis it talks about webers.
I don't suppose it has jetting recommendations for them as well?

[Grant]

While I should really put this in the Wanted section seeing as it is an 18RG thread only it seemed a good place to ask about anyone with a set of second hand leads for an 18RG. They are for a friend in the US.

[Omegaman]

Turdinater, there no info on jetting for webers.
I have attached previous pages 75, 76 to go with page 77.
See How you go, it does suggest how easy it is to change the jets.

OK, so the vacuum advance on my new 18R-G isn't working. I've been experimenting with a timing light and hooking up the diaphragm to different parts of the manifold (including parts which definitely have vacuum) and it makes no difference whatsoever to the timing. If I manually push in the plunger the timing advances plenty so the advance mechanism is working fine, it's obviously the diaphragm which is stuffed.

Anyway I pulled the diaphragm assembly off the distributor hoping it would be fixable, but it's a sealed unit and there appears to be no way to get inside it without destroying it. This means I need a new one - but where from? Does anyone know if other Toyota distributors have a compatible vacuum advance mechanism? I'm going to the wreckers on the weekend to see if I can find anything similar (22R perhaps?) but I was hoping someone might know. Help a brother out, my Celica is so slow at the moment it's almost dangerous to drive!

i have an 18R dizzi (complete with a pertronix hall effect pickup and igniter) with a functioning advance unit if it helps - will swap for information on:
-rotation of crankshaft (has been so long i forgot) when looking at it from front of car
-markings on 18Rx pulleys (which if the 3 is TDC)
-whether the keyway in the 18R cranks is vertical at TDC or offset towards the drivers side

chuck

1. facing engine, clockwise
2. facing engine, furthest left
3. vertical, IIRC


norb... i'll get to that vac advance now. Lucky i'm nice hey?
