Pressure test for leaks

[hooper]

While waiting for the oilpump I did some pressure test with soapwater on intercooler and carbs.It turned out that there is some serious leaking between the carbs,just where the throttleaxel goes through all carbs.

The Throttleaxel has springs between every carbs and on one place it came a lot of bubbles.It looks like some white plastic gasket there.

I guess I have to disasemble the carb rack

Any tips and tricks before I do it?

Unfortuneatly there is no getting around that with carbs there will always be some leaking around the shafts.

You mean that its nothing to worry about?When I blow compressed air in the IC it will leak out in two seconds.

The only way I know if is to install tiny piston rings on shafts and hard coat carb bores where shaft rides, really not worth it.

If it is excessive replace the carbs.

Otherwise nothing to worry about.

The only leak mine has is out the CV caps but not until over 20 PSI, and even then they are very small leaks.
