038 magnum

[Tml061583]

Have an 038 magnum. The Ipl shows a gasket between the carburetor and the intake. My sawdorsnt have one. It also doesn't have a baffle between the carburetor and air filter. The ipl shows that it should. Saw was manufactured in 91. Does any know if these parts are supposed to be on this saw?

Does your saw run? As I see it, these parts should be there. If they are not there I think this gives an air leak.

 

[Tml061583]

It runs and idles. It's really hard to start though. And I feel like it lacks a bit of power.

 

[Tml061583]

Could an air leak cause the hard starting or is that typical with these saws?

 

[DND 9000]

Yes that can give a hard starting condition. The best thing would be to perform a vacuum and pressure test. You say the machine was built 1991. With that age it`s possible that gaskets are leaking (crankshaft seals, case gasket etc.) The hard starting can also come from a partially clogged carburetor, fuel filters etc. Best thing would be to make a complete check of the machine.

Open the low side a half turn and reset the idle.

Put new lines on it as well as filter and brand new zama carb.

Did you run it more? In your other thread you only made one cut. When mine became harder to start I put a new plug in it. All good again.

 

[Tml061583]

Put a brand new plug in it before I ran it.

 

[Tml061583]

No I didn't run it more. Afraid to run it without that little metal expansion sleeve. Don't want to run it lean.

 

[Tml061583]

Replaced the switch control shaft. That fixed the hard starting. It was worn to the point of not forcing the choke closed.

I have never seen an 038 with a gasket in front of the carb. Sometimes the spring in the air filter (choke) needs to be replaced if stretched,or missing etc. A new Bing kit should get it running fine. Set it at 1-11/8 turn open-L,1 turn open-H.
