Dear Andrew. I had the same problem with my petrol mower, i.e. stale petrol. The way I solved it was that upon inspection I discovered a small bolt which was a drain plug in the float, which when I unscrewed allowed me to drain off the petrol into a suitable container. I also noticed that there was some solidified petrol "gel" in the float which I cleaned out. Once I'd refitted the float and drain pug I filled the mower with fresh unleaded and et voilà, it started within just a few pulls of the cable. Thank you for your wonderful videos. I really enjoy watching them. Regards from another Andrew

I dont know about in the uk but in America we have a huge problem w our gasoline supply. The problem is that we cut our gasoline w canned corn (etoh), 10% is standard cut. The problem it causes is that, if left for any time the alkygas will absolutely destroy any aluminum it touches. Was wondering about the chemistry going on there. I have been a diesel and gasoline technician for many moons, but have never heard a good explanation for why the alcohol causes such unbelievable corrosion of aluminum.

As a person with a deaf ear I was surprised that you did not use hearing protectors when running the chain saw. Here in Texas, USA, we use machetes for sharpening sticks as they are a lot easier to handle than a hatchet (hand ax). As I am sure you know, the ideal ratio of gasoline to air is 1 to 14.7. Correct PPE for using a chain saw includes a hard hat with ear muffs and a full face safety screen, gloves, steel toed boots and chaps made of kevlar these days.

Until last summer we had a huge tree in the back yard of our apartment building. Then one day the landlord decided to chop the tree down. So a huge truck came along with some men with chain-saws, and a long telescoping boom. At first they couldn't get the truck in the yard until they cut down several smaller trees. Then there was lots of head scratching because the branches of the tree were tangled up with telephone wires. Then the neighbour was complaining about the noise so they had to switch to electric chain-saws (thankfully). It took several days of kerfuffle, carefully tying branches to the boom, cutting them off with the saw, and lowering them to the ground like a crane. We all watched out of our back windows with great amusement, and keeping our fingers crossed that nothing would go wrong. Which it didn't, except for something going wrong with the truck which a mechanic came along in a van and fixed. They finally managed to cut down the tree and cart away the huge pile of branches and logs, leaving a stump about 6 inches high and 2 feet across. Well, this spring the stump sprouted many branches, which have now grown into a thick bush about 8 feet high. Hopefully, nobody is going to tell the landlord so he won't chop down our beautiful green leafy bush. This is what happens in Canada. Cheers :-)

Basic Science subjects should be taught like this especially chem. India needs a more experiment based curriculum.

you have to put fresh "petrol" (gasoline) nowadays because it now contains a part of ethanol which catches water from the air moisture during winter... you'd better also not stock too much "modern petrol" too for the same reason... (of course, I use "petrol" to stick to the video... but I mean gasoline, the "white petrole" that you use in lamps or heaters is kerosene, an oily stuff close to diesel and unsensible to moisture) Oscar is cutting the wood so violently...

On modern cars, the gas pipes are now ethanol-resistant and you can reprogram the ICU of the motor to fit the ratio of ethanol if you want to keep performances...

Nice... halway through before Andy needs to ignite something! My man!

#1 thing people don't appreciate about the danger of petrol (gasoline), is the way it very rapidly vaporizes (high vapor pressure) and fills the surroundings. If one were to use it outside an ICE, say, to light a campfire, one had better be ready to ignite it IMMEDIATELY. People get skittish or fiddle around with their lighters and matches after pouring it on, and don't realize they've been surrounded by an explosive cloud within seconds. In an enclosed space that danger is extreme. #2 is that people don't appreciate how the very thin (nonpolar) liquid splashes onto and soaks into things much moreso than water. Also leather would barely slow down a chainsaw (it's just skin!), you need specific chainsaw fabric designed to clog up and rapidly stop the chain.

@snafu2350

Leather is still used in assorted industries as a basic PPE substrate because it's thermally insulating (hence leather gauntlets if dealing with v hot or cold substances) & reasonably abrasion-resistant (in this case for protection against inadvertent twitches from being scratched or impacted by minor debris). Also, /hide/ (ie tanned & prepared leather used for the gloves) is not the same as /skin/ (as used for eg fashion clothing): the former is far more damage-resistant than the latter! It won't provide much protection from a deliberately-applied chainsaw, but it's a heck of a lot better vs accidental incidents than thin gardening gloves or nothing at all! :)

But the chainsaw ! Coming from Stihl , no noise,no heat,no fumes,instant low end torque, you can hear the slightest creak from the tree or ppl moving nearby, gets about twenty minutes cut then twenty minute charge while you clear up, the mower is a dream too on 4amphr, and the propelled one is 7.5amphr, so if you wanted you could use that in the chainsaw but that somewhat defeats the purpose because it then becomes heavier than a petrol one.

Drain all liquids during a long period of downtime (keep tanks uncapped while dry & stopper them with gas-permeable foam or cloth scrap to prevent debris ingress). Once their activity season starts again, prior to fuelling/oiling up, grease all bearings, check all hoses & try to ensure no air bubbles (ie allow for a test run before active service). Pretty much the same as what you'd do with any IC-engine-powered device, in other words :)

18:27 If you pack damp sphagnum moss-coir mixture around the base of the green shoots where they emerge from the bark of the horse chestnut log, there may be a chance of roots forming (think of airlayering/marcotting). Maybe the addition of a plant hormone (e.g. gibberellic acid, which can be purchased from Ebay) would encourage root formation. Aspirin (acetylsalicyclic acid) is said to promote root formation. Interestingly, willow family (Salicaceae) trees contain salicin, which is chemically similar to acetylsalicylic acid and salicylic acid. It might explain the branches of willow family trees readily form roots where they touch damp soil.

That event was terrible indeed but quite honestly that comes down to the port authorities/government not functioning properly if you'd ask me. Ammonium nitrate as far as explosives go is somewhat forgiving (takes more than a little accident to set it off), so if it's stored/transported properly and the staff on site follow the produceres set for it things should be fine. And if it isn't intended for explosives but fertiliser instead the mixture can be made pretty safe to the point that even a fire or shockwave is unlikely to be able to set an explosion off. Keeping that stored so long in proximity to a densely populated area was the biggest mistake they made there.

To be fair, many people realize the dangers of chain saw kickback, but the remarkable rate with which gasoline fires can get out of control is less intuitive. Gasoline vapor is extremely flammable and multiplies in size as the source evaporates. It can also drift in unexpected ways, and tends to follow the path from the ignition source right back to its container if it was recently poured. I will say it's not entirely fair to say that gasoline should never be burned outside of an internal combustion engine, as it can be used safely as an accelerant if the right precautions are taken. But there are better fuels for this purpose and for most applications it's better to use a less volatile fuel as an accelerant or external combustion fuel.

Strange you had an extra "not" in the email, must have been subsequently edited. I must say at the outset the biggest FAIL in the English language has to be the whole ; flammable/inflammable absurdity. Yes manys the accidents of vapour backtracking, daft really, cos calorific value is low like trying to start fire with meths, need plenty of carbon, like kerosene or old engine oil, tho in this day and age starting is not the issue, look at Siberia,California or even Australia or Spain,Greece etc, maybe a damp back garden in england is different. But we were brought up on atco lead acid cylinder mower so whole issue of can of petrol didn't arise. I think we used white blocks specifically for the job and newspaper tied in knots. Anyway so "kickback" being a grabbing of the rotating tip to drive the bar violently upwards, when correctly held your left wrist should engage the chain brake, so at least its not moving much when it hits you. Again I reiterate my point, short bar, low rotational inertia, effective brake on eGO 14"/16" CHAINSAW is where this video should have led, if chainsaws were going to be introduced in a gardening program on fire prevention, to explain I.C.E. engines in this way was rash to say the least.
