Aspen in older saws problems?

[nepia]

...Slightly less bad on 2-stroke; even managed to get it to half revs briefly a couple of times but the saw's starving of either fuel or air - probably fuel.

Needs more than I can give it!

 

Thanks Spud.

As Spud says, it could be a bit of crap purged by the Aspen, or it could be the pickup hose and/or carb diaphragms, 'drying' out in the absence of the solvents found in petrol.

 

The solvents in petrol slowly eat away at rubbery materials, removing the chemicals added to rubber to keep it supple. The petrol solvents do, to some extent replace these chemicals, as the solvents keep the rubber soft. When the solvents are removed along with the petrol, the rubber starts to harden and crack.

 

If this is the problem then it was going to happen anyway, the absence of petrol has just hurried it along a little. If new rubber is now fitted and only presented to Aspen the problem will not reoccur and the rubber will stay supple indefinately.

Not directly Aspen related but one of the firms I work with has changed from the red 2 stroke oil to green. My modded and tuned 200t runs terrible when using this fuel. I haven't had a chance to run some regular 2 stroke mix through it yet but will be tomorrow.

 

Would this effect it in any way, ie should I tweak the carb with the new fuel.

 

Apparently the change in oil was brought about by the 4 mix hedgetrimmers coking up the plugs and cutting out all the time.

 

Any thoughts Steve or Garden kit?

...I changed from red (Stihl) to green (Motul) months ago and had no probs at all.

Bloody machines; where's my old bow saw?!

 

By the by Rich... Navara now maintaining over 32mpg with a mix of loaded/unloaded and short journey/motorway driving. All good.

The MS200T is a finicky little beast and could be upset by a different mix, therefore needing a very slight tune, but I dont really see why the change in oil should have upset it unless the mixture strength has altered.

Of course, with it being the said finicky little beast it could be just coincidence and the thing was going to play up anyway.

The new oil won't have physically damaged anything, so change back to the old mix if you can and see what happens before fiddling with screws.

GardenKit, it would appear would it not that a change to Aspen in an 'older' machine would advisedly be accompanied by a change of these rubber things.

Can't wait to use my hedgetrimmers tomorrow; 8 and 4 years old, just been filled with Aspen for the first time. Yikes.

Cheers, that was my plan. Didnt want to start screwing with it until I had tried the regular mix.

No, not neccessarily. I have 'converted' hundreds of machines, most with no adverse effects at all.

Indeed, some have come back with problems such as yours, but not many.

A 5-6 yr old machine may well benefit from a carb overhaul and new diaphragms on a service even if running on petrol afterwards.

 

Having said that, its belt and braces to change the carb kit and the fuel pick up hose and it does not cost the earth.

Thanks.

 

It looks like I won't be making to yours after all for a quarterly supply I'm afraid as I've found a dealership just down the road: all three branches sell Aspen but only the furthest advertises the fact online.

Soz but it is all in the name of Aspen: I wouldn't be buying it at all if it wan't for your contribution here.

Thats cool, I'm just glad you are using it, don't mind where you buy it.
