Interesting, that's some serious speed for just a pipe then! When you say the bloke who put it together is he the husky bloke?
-
A piped exhaust can increase the revs considerably if the macho is ported. Those 3120's used on the gadget show race cart (see the APF thread) are pulling 21k rpm, so a blower at that speed would be like a tornado... What do you recon spud, you could have your drive cleared in a second next time matty drops you a load of logs

The 08s isn't any good for milling Jon, it's only 56cc You could probably retro-fit a chainbrake to the saw, the best option is to take the clutch side off and check if the recess is there for the brake assembly, if it is, just get the parts ordered and fit them, if not, you're stuffed as you have the old type crankcase
-
Run it like you stole it... Or like a work saw. Harder you run it, the better it beds in, which is more power!
-
Woodchip mulch!
-
Yes, but as they said, they got a heap more power from just a muffler mod, the porting almost halved the time through a log!
-
That's good to know, as I've just started reading that thread! But seriously, from inside, I could block the exhaust with my thumb and the intake with my little finger!
-
No, the saw is under warranty, so is currently untouched. It has been ran on 50:1 Stihl super or aspen. As I have said, the saw is far too choked from factory, god only knows what it'll be like ported! In fact, having looked at the factory bevelling (or lack of) I'm surprised they actually run! If the ports were as open as the 346OE and the coil wasn't limited, I reckon the 560 would easily do 15-16k rpm, god only knows how restricted the 550 is!
-
The autotune/m-tronic saws record run time, when plugged in the saw was on 41 hours, max rpm on the last use was 14172rpm, blah blah blah... And yes, a fairly thick, about half a mil or more. But the ports are tiny on this saw and I assume it makes up for this by throwing a fair bit of fuel through the carb, especially as the narrow Venturi would suck plenty through.
-
It's odd tbh wes, I've got quite low hours on my 560 (MUCH less than I expected from it's usage), yet it has substantial coking around the exhaust port, a hell of a lot more considering the saw hasn't done 50 hours yet!
-
Ok, I must have been misinformed on the fine then, or maybe my local TO isn't as expensive
-
Would you take the chance? Considering there could be a £10,000 fine if you're wrong!
-
That's a load of BS, any of the top-end oils can be ran at 50:1, maybe you should have ran the saw in on aspen first, as husky will cover seizes, air leaks and similar under warranty. 33:1 would really coke the ports up, I've seen how bad they are after about 35 hours running 50:1

Didn't plant anything resembling this

The first I would guess is an aspen x black poplar, there were a few at the APF, second is silver birch, judging by the leaf and twig colour -
If it's a blanket TPO, it's got a TPO, I've had to deal with stuff like this, just ring your tree officer and speak to them, they're usually helpful
-
If the brake bands keep going, it could be warping of the clutch cover. Heavy coking is due to a high fuel and oil content in the mixture, this could be the carb, fuel you're using, oil or a blocked spark screen, but the cause for the coking should have been quite easily resolved by plugging the carb in.
-
The 545 has the same power as the 346xp on paper, whilst the main difference between the 550 and 545 is the crank stuffers. The carb and coil will be the same in both machines (saves money for husky) so there may be a slight difference in the transfer ports too. They are very good saws, but it may be worth having a look at the 555 too, as the extra 10cc goes a long way

Whats the oldest 560/550xp out still running thanks
Eddy_t replied to mendiplogs's topic in Chainsaws
It's a very interesting saw, I spent several hours chatting with the tech guys and one of the guys who does the racing saws (he helped build the husky racing cart for the gadget show). It's an extremely choked saw, in comparison to the 357, the exhaust port is less than 2/3 of the size, the intake is a 15x15mm hole and the carb Venturi is of similar size to the 200t! Still, it leaves a lot to play with. -
The 372 is due for replacement first, and husky GB have no idea when that is due out, so the 390 isn't due to change any time soon

I stand corrected niko, I spoke to husky this weekend, there are 3 different coil numbers printed, the limiters are between 13.5k rpm and 14.2k rpm, but the carb also limits the rpm by fuel quality/mix. My saw was running 14,172 rpm on pump fuel and green Stihl oil on Friday, whilst running the full 14.2k rpm one I stuck aspen in the fuel tank. Interestingly, the carb can't be swapped between saws that have different coil numbers without plugging in to change the software. In fact, the carb carries all the data of the saw, including serial number and corrected week of manufacture and test. My saw was actually put into circulation 2 weeks after assembly -
Why did you run away when mediplogs walked into the tent, Justin?

Don't get me started on those curtains!

Sounds like you're flooding it. Cold start: choke on, pull until it fires, choke off, pull until it runs. Hot start: put switch to I and pull until it fires. The 230 has 4 settings on the switch, Off (O) On (I) Half revs (I I I) Choke (I/I) When cold starting, choke off means pushing the control lever up to half revs, but the saw just simply needs to be in the on position after (don't re-choke) if the saw is warmed
