Hi Shavey. I dont see that many Kohlers as the recent JD's do not use them. But the Kohler twins I have seen have the voltage regulator attached to the cowl where the airflow cools it. I have seen several types. So, if you know what it looks like have a surf on the net, several references with pics will come up. Many give JD part numbers too, especially if you include JD in the search. If you have no idea what it looks like then we will have to identify the correct one for the engine so will need the engine numbers. Hope this helps, even if just a little.

Just order direct from a dealer:biggrin:

We aren't too bad down here in Devon either Jon. I will give you a ring Sat pm on the way up.

It is because I am by nature a very generous person Mr Eggs. Actually thats only partly true. I never sell at less than £18.98. This is just a very special "Tuckers" price. (cash only) I do not keep one litre bottles.

Yep, I will bring one for you too. Tuckers special at £17 alright?

And this is the view from the helicopter

But maybe not wear them in Radstock.

Nice one.

I totally agree with your principle AHPP. The problem may be that we falsely refer to this duty as "road fuel duty", when its correct term is "unleaded excise duty (UEXD)" This may defeat a challenge.

Sorry to hear of your trouble Stereo. I am lucky to rarely suffer any problems, I usually sleep like a baby. But the times that I do have troubled sleep usually follow consumption of cheese, chocolate or coffee in the evening. It maybe worth reviewing your diet, and not eating after tea. Just thoughts.

It is good to see factual reports from the likes of Geoff and Old woodchip, guys who have actually used Aspen and found the benefits for themselves. There is unfortunately still a poor understanding of the harmful effects of pump petrol, both to engines and to health. The awareness of these problems is becoming greater, but there are still many users and technicians yet to appreciate the issues and the possible solutions. Many of you know that I am totally committed to the product, but that was not always the case. I have been selling Aspen for just over 3 yrs, but only a year before that I was totally ignorant of the product and believed there was nothing wrong with the use of petrol. I even remember having a hedgecutter in for repair as a non runner about 4yrs ago. When a non runner comes in I try to have a quick evaluation of the problem before the customer leaves. I tip the fuel into a jar then have a look at it and a sniff. This time the fuel was clean, but a strange colour and hardly any smell. I said straight away to the customer "here is your problem sir. I dont know what this stuff is, but it sure ain't petrol. It will never run on this" It was of course Aspen, but I was totally ignorant of the product, so it was the easiest thing to blame. The machine was a Stihl HS45 and the problem was actually the ignition coil, the fuel was fine, but I swapped it for petrol and upset the customer who then gave me a lecture on Aspen, and started me on my Aspen crusade. That was only 4 yrs ago, since then I have learned a tremendous amount about fuel, but still meet other dealers who know as little now as I did then.

I have to come this year Jon, just to bring you your two cans of my favourite fuel! I have plenty more for anyone who wants the chance to stock up.

The pic on the left is the new model CS 280TES 26.9cc saw (introduced in the spring of 2014) The one on the right is indeed the new 360TES.

But the Devon night sky is particularly special Dan:001_smile:

I totally agree that there is constant improvement in materials used in fuel systems to resist the ravages of ethanol in fuel. But no sooner do they produce materials to resist 5% ethanol, the governments introduce 10%. We are on E10 in the UK now, but the fuels do not have to reach E10 for a couple more years. Manufacturers of our type of kit already state that fuels over E10 must not be used so they must appreciate the problems. And, in fairness I did not imply your saw would fall apart. If you read it again you will see that I agreed it will be a slow process, and possibly acceptable Just like you, I have worked on thousands of machines, in fact many thousands of machines, that are still going strong on pump fuel given the proper maintenance to overcome the effects. But I have also seen many machines fail as a consequence of pump fuel. A few have been catastrophic failure but most have been fixable. But fixing comes at a cost. Any good 2 stroke technician will be well aware of the problems caused by pump petrol. Some carry on fixing them regardless, but my inquisitive mind told me there must be a better way. So I investigated Aspen and found it to be the answer. In 3 years of carrying out all servicing and repair work using Aspen my fuel related repair work has dropped significantly. Customers are very pleased with the fuel and most will never change back. Yes, I do have a vested interest as I sell a very considerable amount of the fuel, but as a result I have come to know the fuel and its effects more than most. Argue the toss on price, power, longevity etc as mush as you like. I can see the other side of the argument too. But the dangers to health from pump fuel are beyond any argument and those who use Aspen are more than happy to pay the price for the reduced risk to health alone. Sorry if I come across strongly on this subject, but it is frustrating how far behind the North European countries we are in looking after our health.

Fresh pump fuel and good 2 stroke is indeed OK. The saw will work OK. The fuel lines will very slowly rot, the carb diaphragms will slowly rot, the fuel tank will slowly dissolve, but it will be OK. The piston crown will carbon up, as will the exhaust and the exhaust port, but to be fair, in a hardworking saw this will be a slow and acceptable process. What you save in fuel will pay for a new saw. It will not pay for the damage to your health from breathing in the carcinogenic benzene and sulphur. But what the heck? We are British and nothing will hurt us. Regards the loss of power, well most users will disagree. Aspen is purer and offers a smoother flame front, and as there are no double bonded hydrocarbons present the burn is more efficient. The piston will stay clean, as will the exhaust port and exhaust. The plug will stay clean and the fuel components will never need changing if Aspen is used. But, everyone to their own. The great thing about democracy is freedom of choice.

we are just a spec on our planet, and our planet is but a spec in space.

I had a classic example yesterday of the problems that can be found from the use of pump petrol. This 024 would start, but only run briefly before dying. Classic fuel starvation. The cause in this case was the usual blocked internal gauze, which was blocked by a cocktail of solid material and jelly like gunge. The solids could have been sawdust and, or, solids formed by chemical reaction. The jelly gunge was certainly that caused by phase separation of ethanol. The use of Aspen would have prevented this.

Back in my days on the inshore lifeboat I used to wear 2 pairs of the thin 'nitrile' disposable medical gloves under a pair of thin neoprene sailing gloves. This gave 3 layers and kept my hands toasty warm yet still allowed me to use my fingers. Maybe the same will work under your arb gloves.

There is always a coffee ready in the shop for any arbtalkers who find themselves in our part of Devon, Paul.

Err, yes. I missed that. Being M tronic it should tune itself to any fuel, so I cannot understand the problem you have. How severe is the bogging down? What I do understand though, is that any engine will run happily with Aspen, it is after all, a purer product than petrol. I did some fact-finding whilst in Sweden last week, asking sellers, and users their opinions of Aspen. These guys use way more than we do and report no problems.

I doubt you will need to retune between the 2 alkylate fuels.

Various fuels have various specific gravity (density). Aspen is slightly different to petrol in that respect and may just need a very slight adjustment to the low speed screw on the carb. This is the screw marked 'L' and may need turning out (counter clockwise) by about 1/8 of a turn. Try this and the pick up should be improved. You should then not have to alter this back for petrol. Let us know how you get on.

The american testing method for octane is different to the UK. Its a little daft but the american 89 ron is higher than a UK 89 ron would be. But our minimum Ron is 95 for pump fuel. Aspen is also 95 Ron But there is another octane rating scale called MON, this is a more appropriate scale to use in high revving air cooled engines. Pump unleaded 95ron is only 85 MON, whereas Aspen is in fact 93 MON , so much more suited to our type of engine.
