Stihl 038av carb

[Will H]

I've got an old (but really nice condition) stihl 038av that I'm trying to get working. It doesn't idle or rev properly so I pressure tested the carb which revealed quiet a large air leak which I assume is the problem.

 

The saw is fitted with a Tillotson HK carb and the leak is around the plastic spacer that contains the metering setup. A quick google shows that apparently with age the plastic metering spacer can warp and cause an air leak.

 

So I guess the best thing to do is to fit a new carb, however it seems that they are quite hard to find for a reasonable price - a genuine replacement is around £80, which seems a lot! I've seen some aftermarket ones on ebay but are they any good and if they require a new carb kit are these available? If anyone could point me in the direction of a replacement carb or happens to have one that would be great!

 

Oh and I'm also looking for a double port exhaust for the saw as fitted to the bigger 038 Magnum if anyone has one knocking around....

Let me know the ID of the Tillotson ( the code stamped into the carb body) and I can check to see what alternatives are available.

Thanks Gardenkit, its a Tillotson HK29B

I have checked on this. The Tillotson carb is now obsolete according to my carb specialist. Neither can he supply the metering body.

Stihl list two Bing carbs, and a Zama, but no Tillotsons. The Zama retails at £106 plus vat.

 

Sorry this has not been much help.

 

These plastic components in carbs ar getting a hammering from the Ethanol content of current petrol, hence the swing away from plastic to aluminium.

FWIW those carbs can be found on e-bay US for around 35-40 dollars US funds and they ship world wide .Of the two the Bing is a better carb as far as performance .

I scrapped an 038 a while back but I think I kept the carb - I am abroad at the mo but back in UK in about 10 days or so - if you are not successful by then drop me a line and remind me and we will see if it is still there

 

Cheers

I think £106 + VAT is out of the question, but thanks Gardenkit for taking the time to check for me!

 

I had a look on the US ebay and there do seem to be some good deals - however last time I ordered a few small parts from the US I was stung by customs and had to pay VAT, import duties and a handling charge

 

Mac, thanks for the offer! I'll PM you in a couple of weeks if I haven't sorted something out!

[Will H]

Just a quick update on this, muldonach kindly sorted me out with a replacement carb for the saw and it now runs perfectly!

 

Thanks to everyone who helped me with this!
