AV had been round 10+ years by that point, there are old Stihl contras out there with AV dated to the early 60's. What you've got to remember is, the materials were poor, half of the plastics hadn't been invented, secondly, most of today's safety features were optional extras, reserved for the kind of people whom today have heated handles, trio-brakes and other bits of kit to make them super safe Sent from my iPhone using Arbtalk

Unfortunately Stihl don't do a domed piston in that size, so you will have to track down a piston specifically for the CT Sent from my iPhone using Arbtalk

The stellite block near the nose is for a helper handle to be mounted, I have a bar a few sizes up, and waving them around on the 1106/1109 series saws definitely needs a helper handle! I don't know how you'd add an auxiliary oiler as there is no way to feed into the bar, and the steel used is incredibly hard so adding any additional feed holes is almost impossible!

It's in the manual Sent from my iPhone using Arbtalk

This, unfortunately has been my thought many times, as I've been sweating my balls off in the baking sun, even the arse vents don't cool me down enough, and walking round with a leaf blower down your trousers isn't practical Sent from my iPhone using Arbtalk

You can wear type A's for climbing if you've done a risk assessment for it AND have a suitable reason NOT to wear type C's, unfortunately, most contractors specify that you must wear type C's only, so check the contract first, you may be SOL and just have to lump it in the heat Sent from my iPhone using Arbtalk

From what I've heard, the new 150 has been designed with maintenance in mind, more grease points, which have been located close together so you don't miss one out. But it's hear-say, so it may not be true! I hope it is though, the 150 is a bugger to work on! Sent from my iPhone using Arbtalk

Extra work? It's one cut! The idea is that the butt end of the tree hits the ground first and eliminates the shock and impact of the tree hitting the ground. The Humboldt itself is just an upside-down gob cut Sent from my iPhone using Arbtalk

Yeah, happened tons of times, bit of crap has jammed it. The tolerances of a sprocket are a lot tighter than you think! I usually free them by forcing it tbh Sent from my iPhone using Arbtalk

It's strange that snipes are only used in exceptional cases in the uk, whilst the Humboldt face cut generally isn't used, even in timber production, yet the cut is designed to reduce impact stress on the tree Sent from my iPhone using Arbtalk

I thought he ran between 33:1 and 40:1? Sent from my iPhone using Arbtalk

The buyer says you can have as much or little as you like... Somebody buy a cheese wedge shaped piece from the base, on the house side Sent from my iPhone using Arbtalk

No, your points are very relevant, I use aspen in my ported saws, but I find aspen precipitates it's oil perfectly and leaves a residual oil lining anyway. But those hunting for the slightly higher compression values do use a lower ratio, such as wyk and his 361 of doom having given my 090 high compression, I tend to shy away from that! Sent from my iPhone using Arbtalk

Stock saws yes, but ported saws have different timings so the residual oil will help seal the cylinder quicker, especially on a higher rpm saw where the exhaust port has been raised to give a substantially higher rpm range Sent from my iPhone using Arbtalk

The point of a lower ratio is that when the oil precipitates, it creates more of a seal around the piston and ring(s), which increases the overall compression, as the oil seals the cylinder as the port closes, so less mixture can escape, whilst it may not be much in terms of port timing, it CAN make a huge difference in psi, it doesn't always!

The only way we would know is by sacrificing a saw by tuning it on 50:1 and then dropping 25:1 in it, and then doing the opposite to another. I'm not willing to sacrifice one of mine to prove either theory Sent from my iPhone using Arbtalk

You can't get hybrid fruit unless the plant itself is a hybrid, the fruit is produced by the parent plant and has no influence from the pollinator, only the seeds do. But remember, plants hybridise a lot more readily than animals, and generally are fertile. The blackberry/raspberry crosses are confusing enough! Sent from my iPhone using Arbtalk

The point of the statement is, whilst the same amount of mixture is going in, the fuel/air ratio is decreased, so the engine revs higher and burns hotter as there is a more complete ignition. The oil prevents a seize for so long, but an extended period of higher rpm would produce a temperature where the oil would reach a flash point before precipitating on the cylinder walls above the piston prior to combustion. This effect would cause a seize. Sent from my iPhone using Arbtalk

West coast is the contractor I believe, but still, get the owner to ring WPD, somebody will be dispatched to survey, get permission and cut it Sent from my iPhone using Arbtalk

Depends, where is it in the mids? It's usually down to what the surveyor thinks can be done, if it's below the line, or to the side, it'll get cut live, if it's above, it'll need switching off! Sent from my iPhone using Arbtalk

1. I work utilities, I have to renew EVERY 3 years, in that time between renewals, the work practice HAS changed from G55/1 to G55/2 2. I have an operators ticket for MEWP's, that has to be updated every so often, especially working as a live cutter 3. My first aid course taught me how to apply a tourniquet, it was the basic one day emergency first aid course, so you need a better trainer 4. I have met a fair few who've had their cs tickets a hell of a lot longer than me, I'm shocked they're still alive 5. I think driving refreshers should be made mandatory. 6. I've paid for all but 3 of my tickets, I'll quite happily pay for an update in a few years, I think cs34 will be the next 'update' 7. Your objection with trainers 'that don't have a clue', it's your money! Shop around and find one you think does! I was trained by a bloke called Ian Morgan, you may have heard of him, many people rate him highly, maybe you should visit his stall at the next APF. Sent from my iPhone using Arbtalk

That's 11kv in that photo. By law, the minimum clearances are 0.8m (up to 33kv) for an unclimbable tree, 1.2m for a climbable tree, although WPD say 1.2 and 3m respectively, with an additional 5 years growth Sent from my iPhone using Arbtalk

I would imagine it's fantastic for making fruit liqueur alcohols! Peach vodka, plum gin, etc. It's interesting some of the grafting techniques used, I'd only heard of the leaf bud being used on roses, may have a play myself! Sent from my iPhone using Arbtalk
