Ethanol Shield 2 stroke

[Eddie@aspen]

Must admit,now I have got my head round the extra price I'm enjoying using aspen, my 200t's ain't too sure though!

Hi IC Trees,

 

Give me a call on 07568 108953 and I will see if I can help get your 200t's running better on Aspen.

 

All the best

It is probably the accelerator pump Ian, all rubber components harden once they are out of contact with pump fuel. It is common on saws to start leaking around where the fuel line pushes in to the tank.

 

I have recently taken to replacing the pump rather than blanking them off as I used to. If you get stuck, send them in one by one and I will sort them out for you if Eddies advice doesn't sort them.

 

You may find just opening the L screw up 1/8th turn anti clockwise and tweaking the idle screw clockwise will do it.

Yeah spoke to Eddie, thanks. Spud, i tried the screw settings but made v little difference.

Just had a weekend of MS200 carbs, some really weird ones this time, a flake of black stuff under the welch plug - all the jets, check valve were passing a jet of cleaner fine but no idle and eventually guessed it MUST be the welch plug....and it was.

 

The other was a leaking welch plug on the accelerator pump, a blast of cleaner gave a jet coming out of the back of the carb - never seen this but got it sorted.

 

You live and learn - the last was a perforated pumping gasket, seen this a few times now!

 

Best action is to either swap the carb out for a new one or to get someone worth their salt on it!

The trouble is finding someone like that Steve, any ideas?

ALL engines, no matter if outboards, mowers, cars, saws etc will last much better if using non ethanol fuel. Its not scaremongering, its just fact.

 

As Eddie says, most modern engines state that 10% is the very max amount of ethanol that their engines can tolerate. I have quickly searched american sites for mercury and honda outboards who also state 10%.

This is all very interesting reading. I've not seen anything on the boat forums to indicate that anyone's very worried about ethanol in petrol (unlike concerns about low sulphur Diesel following the demise of red). I suppose big outboards just simply use too much petrol to even consider the use of Aspen, and maybe another factor is that you don't really breathe the exhaust fumes.

 

From my point of view our tender uses a four stroke outboard, and we don't even get through 5L in a year. It would really cost very little to switch in our case.

What have the Welch got against these saws?

I am quite surprised that the boat forums don't debate the issue. I know several marine engineers who are very aware of the problem caused by stale fuel, and ethanol. When you think about it, the leisure boat season is very short and generally over by September. The boat goes away under cover (or not!) in the hope that there may be just one more outing before winter. of course that does not happen so the poor old boat does not get winterised properly and is dragged out on the first day of early summer. The petrol is at least 8 months old and there is nearly always trouble.

 

I am just as bad with my boat, even though I know better, and have had my fair share of hasty pre season repairs. I once suddenly realised that my 'new' 2.5 suzuki auxilliary was in fact 3 years old and I had never used it. It had the same petrol in as when I first fitted it. No surprise really when it did not start!

 

So for the last 3 years it has had Aspen in. It has still never been used but starts first or second pull every spring when I test it.

I even run my 25hp Merc Bigfoot on Aspen, its just so sweet and no smell at all when pottering around creeks with a tail breeze. And it starts first time, every time. It was never as good on petrol.

Hows about you Barrie, man hug:001_tongue:

:001_rolleyes:Very funny:001_tt2: Finding that red stuff that Zama use on their carb welch plugs appears to be the holy grail. I have used most stuff and the best has been cyanoacrelate (superglue) but am now trying shellac and also Loctite 638 as an experiment.

 

Even made my own stainless punch to put them in on C1Q carbs!
