The Black Hole

Isn't the 6100 a strato saw? Or is it the 6400?

 

So tis, yes. Not up to speed on downsides of stratos if there are any?

Not that I've seen/noticed, iirc, the IPL shows it uses the newer 2-part carb on husky patents rather than the older carb split (now owned by Stihl), so it's an even and controlled feed (so you don't get the bog that Stihl's suffer(ed) with.

 

When dolmar finally gets the autotune carbs, it'll be interesting which generation they use.

Why will they go autotune? Echo have sworn they never will...

Emissions control, sooner or later, it'll be self adjusting carbs or fixed jets. Echo is missing a trick with the e-carbs, they're designed to run an optimal mix for correct rpm. Too few people know how to tune a saw and either end up with a saw screaming to its demise or running sluggish from an over-rich mix.

Despite people's misgivings for the self adjusting carbs, I find that they work wonderfully, I no longer have to dick about with a tach and screwdriver when I port them. A lot of the 'problems' people have are user error, but unfortunately there's a lot of misunderstanding on how to set them up.

Aspen is about £18.00 a gallon no?

 

= £3.60 per litre

 

Super Unleaded British Average = £1.25 per litre

 

Stihl HP Ultra £17 per litre (0.34 pence for each litre of petrol at 50:1)

 

So mix aspen and petrol 50/50 and add the oil and you get a cocktail that costs £2.60 with half of the harmful emissions of straight petrol. Use that in a strato saw and you wipe out half the emissions again (they say up to 70% but lets be conservative) so you end up with a quarter of the emissions that you started out with running normal petrol in a last-generation saw.

 

A lot of guys are saying they would move to aspen if only it were a bit cheaper. Well, this option is "affordable" and would bring the emissions way down. Is it a good compromise? I haven't tried it yet, will when/if I get my new saw. Maybe on the days I have to do a lot of bucking or cutting through stacks in close weather or heavy cover I'll use straight aspen, and maybe when the wind is up and I can position upwind or crosswind I'll go straight petrol.

 

Another benefit of the cocktail is it reduces the ethanol levels by half, if you are worried about that kind of thing. Seems that saws can cope with a bit of ethanol, but not too much...??

 

I reckon aspen dealers would sell more product if guys were mixing it with their petrol.

 

Virtual Prize for whoever comes up with the best name for the cocktail..........

That Sir, is the ultimate, rolls royce of fuels. Way to go.

Hi all,

 

Unless you have 2stroke oil to use up why would you mix?

 

Aspen2 FRT has an oil designed for 2stroke air cooled engines and they have spent years testing it in chainsaws to give the cleanest exhaust and best all round performance.

 

The oil used out performs the leading low soot oils from the top saw manufactures and is even approved by them.

I really can't understand why this bloke is mixing aspen with normal fuel?? It defeats the object of Aspen does it not?

[GardenKit]

I dont understand it either, but I think it may be more Irish ramblings than serious suggestion.

 

But as long as people buy Aspen, I don't care what they do with it, as long as they are happy:001_smile:

Interesting post! Nice to read something creative. Yeah Aspen is expensive; but life is too short for living an even shorter life.... cheers, Steve
