2015 Ms181 Non Start - at my wits end!

Did we ever sort the issue, so much going on and not sure if between insults, hugs, bollox and brexit that we actually got there

@Darkslider cured his problem by having a dealer replace the gaskets, needle valves and diaphragm with a new car kit.

 

The 181 is quite different from the 181C which I am having trouble with in that it has no primer bulb whereas the 181c has one remote from the carb.

If we did, I suggest we talk about toilets....those German inspection ones....what are they about,

AIUI they eat a lot of smoked meat and historically provide a warm dark home for various worms, the shallow bowl allows inspection for  the offspring before they get flushed away to infect the next generation of grazing animals. Last experience I had of the shallow bowls was thirty years ago, it could be disconcerting first time if the gooly bits dangled low

Thanks - my MS181 was a nightmare today, took ages to fire, wouldn't restart after a couple of minutes when I stopped it, and later refused to play at all. So in conclusion - carb then? Ome thing I read earlier was to open ip the 'L' o the catb a bit which sounds wrong because it was working OK as it was set.

 

 

-edit-

Forgot to mention last night about petrol. I run mine on supermarkt petrol - and also the car (nearest petrol staton). Anyway,the car engine warning light came on... and has clered itself as soon as I put Shell petrol in it - better quality petrol? and I am thinking that over time this might have affected the saw So next week going to get Shell petrol to try

I'm not convinced of the argument that supermarket fuel is inherently worse quality than premium fuel stations. All the fuel related problems I ever hear of are down to contaminated (water usually) fuel of some kind, which I've been told is down to how well the operator maintains their tanks which would indicate it's probably only small independent garages you've got to worry about, most big chains should be fine?

 

Could be miles off however!?

I've had this with both saws and the vitara in the past, not the fault of the petrol station either. With the vitara it was a broken fuel cap that allowed rain to drip onto the one way vent in the cap, as the vacuum formed a droplet of water was sucked in. When the engine stopped I filtered out a litre of water from the fuel after the nice AA man said I had a broken carburettor and towed me home (it's single point fuel injected).

 

The chainsaw exhibited similar problems to  what is happening to the current MS 181C, the engine fluffed when the throttle was opened. in that case it was a husky and I popped the welch plug under the main jet off and could see a small globule of water in the well under the jet. I shall flush the carb through with alcohol to sort this with the stihl but I think the fact that air is being sucked into the primer bulb indicates another problem with sealing. First step with this will be to replace the tank filter.

 

I cannot see a cheap replacement carb cheaper than £80 otherwise to save time I would just do a swap.

For the petrol there is plenty of anecdotal evidence of the big petrol stations being better. I did some work at Grangemouth - the base petrol is the same but it is given brand specific additivs as it's being umped int the tanker (in highly controlled quantities too). They all meet the minimum standards but its the addatives that mae the difference. For the sake of 1l if fuel and not much more I'm gong t give it a go and see if it helps. Sort of convinced me when the car 'fxed' itself hen t got different petrol.

 

 

As an update< i adjusted the 'L' o the carb amd it started better today but still not perfect. I'll ry the different fuel next and then look at mechanical things

How about special the higher octane stuff ive never used it?

 

Is it worth splashing out for premium petrol?

Premium petrol brand promise so much, but are they really worth it? This guide from Rias should be able to help you...

 

Also this E10 fuel they want to introduce soon will it knacker up chainsaws?

High Octane wont benefit chainsaws with a carb . It is made to resist " knock " or detonation in modern high compression fuel injected  engines . It has been proven that when used in relatively low comp engines that they run poorly .

I used to use 97/98 octane pump fuel because (in France) it didn't contain ethanol.
