Zama carb

[coppice cutter]

I have a Makita RBL 500 backpack blower fitted with a Zama carb which has started over-fuelling quite badly.

 

Reading through some past threads it seems to be something which can affect some of the chainsaws as well and the fault seems to lay with the spring/metering arm.

 

Would I just change these two components first and see how it does or would there be anything else in that area that would be suspect?

 

Also, Oregon do plenty of kits for Zama carbs, would there be any way to identify the specific carb on the blower to determine if one of these kits would fit it?

 

Thanks.

Zama carb kits are expensive so when I had problems with a Still HL75 long reach hedge cutter I bought a non genuine carb for it from L&S.

 

It looks like you need part number

 

541-60430-03 but it might be worth asking if they have a non genuine carb.

 

BTW my venerable Makita back pack blower is amongst my most reliable bits of kit.

Thanks for that.

 

Mine is the RBL (older?) and I'd figured out that my carb was 541 60430 01.

 

Carb parts appear to be available individually and while some parts are a bit serious, metering arm and spring are little more than a tenner.

 

Yes they're a good bit of kit, mine is now well up in the teens of years and this is the first issue with it in that time.

I have searched for a number on mine but can only find the body type (C1M) and not the model number but suspect it's C1m-fr1 from googling . I would get parts from L&S or Rowena motors, hugo is very helpful there.

[coppice cutter]

Mine is o1M which I just assumed to be the manufacturing machine number or such like as it's so short.

 

But I'll search a bit deeper based on that.

 

Thanks.
