I am hoping this issue is fixed. The local Stihl agent returned my call and he had a secondhand filter unit from a 038AV which he would sell for £4.80. So I went to see and his filter unit was identical to mine but his Choke Shutter worked perfectly when installed in the 038AV from which it came. The Switch shaft looked almost identical but perhaps a bit more hooked. So we fitted my filter unit to his 038AV and it also worked well. So I bought a new switch shaft and will fit on my return. Many thanks for the help you have given me. Tim

Thanks for the info, Garden Kit. They are metal mesh filters. In the light of this all except the choke shutter are correct. Where do I find the serial number? I have made a call to Stihl agent for the shutter but the spares man is to call back. I am off for a fortnight's holiday on Sunday so I guess I'll have to fix this on my return. Tim

I think the filter may well be wrong. As I have said the cam on the shaft and the peg on the choke shutter do not meet when choke is selected. I have removed the choke shutter to read the part nr, it is Stihl 1119/0 1. This does not conform to the usual numbering format but that may not be important. More importantly it differs from the value given in the parts list which I downloaded a day or so ago (and provided in another post in this thread. Thanks). This is 1119 129 2100. The nrs for the mesh filters are 1119 120 1600 (carb side), 1119 120 1605 (user end). This last is correct but the carb side nr should (it seems) be 1603. However, both parts fit together well so should I simply try to get the 'correct' choke shutter? Unfortunately I cannot find a picture of the choke shutter (2100) which is good enough to show the length of the peg. It is quite cheap so it could well be worth the punt.

Thanks to you both for the quick reply. I have taken another look at the choke shutter but it looks fine to me. I attach (I hope) two photos. One of choke shutter as is. The other of the switch shaft. The cam which operates the shutter can just be seen. Does this cam look OK? It seems in original condition to me. I ask the question becasue it occurred to me that a part of it may have been broken off in its past life. Thanks for the help.

Hi. I am new to the forum although have followed it over the past year or so whilst I have used small chainsaws. I recently bought a Stihl 038AV Magnum for some larger work. It works well but is difficult to start. I know from this forum that they have a reputation for being difficult but this can take 50 or 60 pulls (when I can manage it). When cleaning the air filter I noticed that the Choke Shutter it contains does not appear to be operated by the 'cam' on the rhs of the Switch Shaft when the choke position is selected. When the shaft is in the choke position the cam is at least a mm from the 'peg' of the choke shutter. My first reaction was that the filter or shaft must be out of position but this is not the case. They are both too precisely fixed. The part numbers on the air filter seem to correspond to those given in an old service manual for 028/038 saws which I bought on the net. So it doesn't look as if the wrong part has been fitted by an earlier owner. I have no idea how this can be fixed so any suggestions would be really appreciated. Thanks
