Ricko Posted November 27, 2011 Report Share Posted November 27, 2011 A friend gave me an ancient Stihl 08S, I have fitted a new spark plug and drained the fuel and replaced with Aspen2 (still doesn't start), can I have your advice on getting it going. I am/was mechanically minded but just being a bit lazy!! Cheers Quote Link to comment Share on other sites More sharing options...

I am/was mechanically minded but just being a bit lazy!! Cheers First, check it's got a spark. If that ok, pour a small amount of oil/petrol mix in the plug hole and try to start it. If it runs for a few seconds then stops, check the fuel filter in the tank. If that fails it may need the diaphragms in the carb replacing, especially if it has been stood for a while.

Paddy Galore! Posted November 27, 2011 Report Share Posted November 27, 2011 does it have compression? strip and clean the carb, filters, and set the carb back up. give it a whirl Quote Link to comment Share on other sites More sharing options...
ME Posted November 27, 2011 Report Share Posted November 27, 2011 (edited) Get your todger out and try to start it with the chain resting on it. $ods law dictates that it will start Edited November 27, 2011 by ME Quote Link to comment Share on other sites More sharing options...
fruity Posted November 27, 2011 Report Share Posted November 27, 2011 Is there enough spark there to start it in the first place ?? Quote Link to comment Share on other sites More sharing options...
Paul223 Posted November 27, 2011 Report Share Posted November 27, 2011 how are you trying to start it? has it fired at all usually with a stihl full choke, pull it till it tries to run then choke off full throttle and it should fire up, any more pulling it over with full choke will end up flooding it is the plug wet does the plug spark Quote Link to comment Share on other sites More sharing options...
Rupert Posted November 27, 2011 Report Share Posted November 27, 2011 if its bin stood long enough the residual fuel oil mix in the carb evaporates off but leave the sticky **** in the carb,some of the tubes and passages are really fine in there 1 establish fuel flow 2 verify spark 3 take to repair outfit Quote Link to comment Share on other sites More sharing options...

Ricko Posted November 27, 2011 Author Report Share Posted November 27, 2011 (edited) you missed out shout and swear at it before taking to a shop I have an old McCulloch (which in all fairness I bought in 1990 and have since given up with) which used to succumb to this treatment. 4 hours spent on a Sunday morning to get it working for 30 mins of cutting!

Dougy Posted November 27, 2011 Report Share Posted November 27, 2011 Got one of those beasts in the garage (well i hope stihl i have) Now i am probably in the wrong here but what i have done is,-fill with decent fuel, take out plug & heat it up,squirt some lighter fluid in the pot, replace plug and lead and start not failed yet. Must admit its been replaced with a newer more upto date safer 180 now with a nice chain brake on 08S is a bit OTT for logging Quote Link to comment Share on other sites More sharing options...
Edward Posted November 27, 2011 Report Share Posted November 27, 2011 I would check the compression. Very simple, make sure its switched off then hold it by the starter, if it drops quickly its got poor compression, if it drops slowly then it should be ok Quote Link to comment Share on other sites More sharing options...
paulf Posted November 27, 2011 Report Share Posted November 27, 2011 A new fuel filter and fresh fuel would be my first port of call. was the fuel mix you used fresh? did the tank have any old fuel in? Quote Link to comment Share on other sites More sharing options...
Gav912 Posted November 27, 2011 Report Share Posted November 27, 2011 I've just got my 7 year old Husqvarna 346 back from the shop after it suffered a similar problem. It hasn't been used for a few months and when I went to it it would fire but not run, just needed the carb cleaned out and new fuel hose fitted as it had started to perish, only cost £20 to get sorted so I'm a happy bunny.......one of the larger local Husqvarna dealers told me to sling it in a skip at that age as it wasn't worth repairing.....won't be asking them again Quote Link to comment Share on other sites More sharing options...
jpbeaver Posted November 27, 2011 Report Share Posted November 27, 2011 Ricko where are you based? I have an 08s in the cellar and an old stihl stone saw based on an 08s. If you need parts let me know. Quote Link to comment Share on other sites More sharing options...
Chris Bb Posted November 28, 2011 Report Share Posted November 28, 2011 Just use it as an ordinary saw. Simple. Quote Link to comment Share on other sites More sharing options...
harrycatcat1 Posted November 28, 2011 Report Share Posted November 28, 2011 Dont ask on here about chainsaws I had one that didnt start and a chap offered to have a look at it, I took it to him and I never saw (not a pun) it again. He is still waiting for a part a couple of years later I now use a hand saw. Quote Link to comment Share on other sites More sharing options...
Catweazle Posted November 28, 2011 Report Share Posted November 28, 2011 Chainsaws are dangerous enough, without using an old nail like that. I'd dump it and buy something more recent. Second opinion ? Read what the pros say; http://arbtalk.co.uk/forum/chainsaws/6731-stihl-08s.html Quote Link to comment Share on other sites More sharing options...
