Hi been trying today. check the coil, primary 1.2 ohms, secondary 8.2k ohms. Thisis in spec. if the saw fires which is rare. It runs for about 1 second then dies think I’ve managed that three times. Normally it just floods after lots of pulling. It just does not want to fire up there’s not even a hint of life. ive tried fuel in the carburettor nothing. in my possession, it’s never been running to assess anything else. That is all the information I can give. thank again.

Sorry my mistake oil seal 13 x 21 x 4. regards

Hello thanks again for the replies. yes it is the larger one (13x21x19) the smaller one seems to be still in stock in various places online. so I did have another look on eBay and found this. Oil Seal 5mm-15mm Rotary Shaft FKM Rubber Double Lip Stainless Steel Spring TTO WWW.EBAY.CO.UK Material: Fluorine rubber skeleton oil seal. 【Wide Application】- Oil seals are used to protect shafts and... Only thing is it’s Max operating temperature is 260°C. I’ll have another look at the carb I have cleaned and rebuild that. I’ve swap carbs with a different saw (010av) that runs great and both carbs work on that but not the 011av which makes me believe the problems elsewhere. Could a bad oil pump cause the issue, it is run off an impulse of the engine and when you test for pressure and vacuum, you have to blank that off. thanks again for all the support.

Hey thanks for the response and yes cylinder was off but it’s all back together again was abit tricky but managed, didn’t want to risk any chips getting in there. any thoughts on where to get the oil seals? unless you have any bright what the problem might be.

Hi I recently acquired a Stihl 011av. it was in poor condition and won’t start. the saw has 150psi compression, good spark and gets plenty of fuel. I’ve cleaned the carb and put a new gasket kit in it, in fact, I swapped out a carburettor from a different saw same model that did work and put that on it and it still does the same thing just floods. ive also replaced the gaskets under the carburettor and reed valve. The spark plug threads were stripped as well, so I fixed that and put gaskets on reinstallation. if it does start it runs away then dies. I understand I need to do a pressure and vacuum test however I don’t think you can get the oil seals anymore, well I can find one but not both. I don’t own a pressure and vacuum tester.So the cost of all of this makes me think it’s not worth it unless anyone on here might know where I can find the seals I require or insight into the problem. 13 x 19 x 4 - 96400031320 13 x 21 x 4 - 96400031330 (can’t find) any help / advice much appreciated. kind regards
