Stihl cobi problem
I have a Stihl combi system running a hedgecutter sometimes with the 1m extension bar. I went for the KM 130 R engine, which is a 4-mix.
Used twice this year, no problems. Today though, it kept cutting out, backfiring and generally sounding really rough. Same batch of fuel used in half a dozen different machines today, and they were all fine. Any ideas? |

Re: Stihl cobi problem
sounds like the coil pack to me but may well be the spark like Mr Woodpicker said

Re: Stihl cobi problem
i bought the 4mix pole pruner last year mark, runs like a bust couch, really slow on the uptake, never broke down but just not as good as the 2 stroke version.

Will have a go at it tomorrow as local dealer down here didn't know what the correct file size was for a 3/8" pitch chain, so I don't trust them to diagnose the problem, fix it and charge me less than 2 weeks labour. |

Re: Stihl cobi problem
I got a HL100 4mix which never use to want to start and was really slugish on the uptake and use to cut out alot. I put it down to the all in one air filter which seemed to be really restrictive. so i changed it with some less retrictive foam and its no where near as bad.
