vacuum tester

[Dean Hylton]

Has any one had any experience using a vacuum bleed down kit to test saws?  I have heard a little about them and am interested in finding out more.  Also where does one get one and what is the cost of such a unit.  I have heard that it does a 15 min. test and checks everything including the seats in the carb.  p.s. I just bought a Stihl model b digital tach today ;D I feel like a kid a Christmas with a new toy running around and checking evrything that might possibly have an rpm. 8)

Hay Dean
Aren't Huskys,  Stihls and some of the other saws made by Electrolux? Maybe they have a vacuum tester eh.  8) 8)
Heck maybe you can borrow it from the missus.

There is a simple pressure test using a bulb and an inline gauge.

As long as you had an adapter to fit the chainsaw (14/18 mm?) why could you not use the one for an automobile with your air compressor?

It might be too much force.
You only need 7psi.

I talked to a guy who said that Stihl use to make a complete leak down kit that tested everything including the carburetor but that the kit was $700 and was discontinued last year.  I have also been told that I could use a brake vacuum tester. I just wanted to talk to others who have had experience with these and see wha tothers use. What they like or dislike where they might have gotten them and price. Vacuum leaks are always a pain in the back side and looking to make the job easier.

7 psi - probably would use a brake flusher kit then.

Phoenix makes a nice line of pressure testers/brake flushers  and they start about $40. northerntools.com sells them.

Here's a marine site that knows about them ...

Thanks Keven.  Small problem though. I work for Madsens's competition. I work for the other Husqvarna dealer in town.  I asked them about it last week and although showed it to me they were not real happy about taking the time to explain it much.  I completely understand though.  I just thought that some one in here might have a little experience.
