Check out Nardek, http://www.nardek.com.au/

I bought a diaphragm off them a while ago for about $60.
Buy from them direct as places that sell their stuff mark up the prices and you could be paying 20% more.

As long as it's below the red line it should be ok. The guage should sit around half or just over half when hot. Make sure you use coolant and not water.

When you say it doesn't idle in gear, does it stall or chug or what?

The idle in gear should be approx 650-700 rpm and in neutral or park it should be approx 850 rpm. When cold and warming up (if the choke is working) should be at about 1100-1200 rpm. You will just need to adjust the carb to get it right.

Make sure your ignition timing is set properly, 6 degrees from memory.

sorry dude i did mean diagraram to see what vac hose goes where :)

the temp thing your spot on its sitting just over half when hot.... so that ok

in park it idles around 800rpm and drops to about 600rpm but it stalls after about 10secs or so and if i get it too idle without stalling then put it in park the idle jumps up to around 1200rpm and it slams into gear at that

Check the vacuum hoses. The carb might need to be rebuilt. The problem sounds like it's to do with the carb.

I couldn't find a diagram in my manuals. What hoses are you unsure of? I can tell you where to connect them. Most of them connect to the manifold.

the stalling will be due to a vac hose going to the wrong place on the carby..... or maybe a vac hose missing.....

About $50 for a kit available from Repco, Autobarn etc...

Or about $200-$250 for a rebuilt change over one from carb specialists.

They can be fiddly. There is a lot of pieces and you need to have patients.
