help identifying parts i need?

Post by **ben739** » Thu Nov 30, 2006 9:49 pm

i want to replace the gaskets off the manifold that the carb eventually mounts too. i think there are two divided by a spacer. what are the gaskets called excatly so i can order them? are they as simply named as carb/maifold gaskets???

You need to ask for '2 carb to manifold gaskets', please of course!
ps: state engine size.

Most unusual to change them - you get loads in a head gasket set - and since you are accumulating spare parts - that will be a certainty to take with you - in fact, take 2 !!!

When I took the carb off I made those gaskets from an old corn flakes box and they don't seem to leak.

if they are going bad, what will seap by the gaskets there? oil/fuel?

Nothing will weep from those gaskets - but they'll start letting air in, weakening the mixture and usually increasing the idle speed. The standard test is to put some WD-40 or oil on the join and see if it bubbles or the exhaust emits blue smoke.

Or petrol and listen for an increase in revs/idle speed.

DO NOT DO THIS. Whatever one does in the privacy of one's own garage is one's own business, but for public consumption categorically do not start applying petrol to an area above a potentially hot exhaust. Safety first.

Oh no, don't start all this stuff up again, we've only just got over the negative comment thing. People are going to use their common sense when using petrol for this purpose and use a thimble full or such, lets not screw this site down too much!

the only thing I can find in the T&Cs is

"Consider that young children may be viewing this website."
so I don't think it needs moderating!!!!

Petrol also needs a spark to set it alight, I think, so the exhaust manifold being hot is not part of the magical oxygen/fuel/ignition source triangle. Safety first, naturally, but...

Andrew.Your little picture at the bottom of your post?
looks like you may have used petrol (gasoline),for
something in your vehicle.

In some respects I agree that we live in too much of a "Nanny State" these days. However, I find that a lot of people do not seem to have any common sense.

Heat can be a source of ignition and Petrol vapour can spontaneously combust at 200 degrees Centigrade which is well in exhaust manifold range

most motor factors should sell the gasket....prob not tho....buy some gasket paper which is about a4 size and cost about 10p
