I think I saw a rabbit crawl out of that hole:lol: Nice one!

And don't get hung up on that cylinder base on the first pic left hand side, it is a clam style engine where the base of the cylinder forms the upper part of the crankcase. Closed transfers are generally found on more expensive Pro saws and open on semi pro/homeowner saws, there are many exceptions to this, the MS200 being one of them. As Wes says, closed ports generally have better flow and velocity plus a rounder top to the transfer is far better than the angular affairs usually found.

Man.....18,000rpm, thought my saws were fast revving:lol: It is the oil that dictates the mix and not the saw. Most decent quality oils nowerdays mix at 50:1, there are a few exeptions such as Amsoil at 100:1. The 25:1 comes from the 1960s - 1980s where the oil was a bit under developed. Run a modern machine on this and it will smoke like beggary and carbon up. Use decent quality oil and mix to the OILS instructions

Yeah - you probably purchased an oil cap for the fuel tank or vice versa:lol: I have noticed that the caps can become tight and then it gets so when you try to flip the cap down, it is out of position...bloody annoying IMO and easy to get the fuel spilling out Grrrrrr

TBH I run a tad more than 50:1, it is just my choice, the theory you are talking about is that the more oil you have, the less fuel there is in the mix so you are in fact leaning the saw down by adding more oil, there is some logic there but if you tach the saw to run the rpms it should......... My take is that if you add a little more and then ensure your saw is set up correctly on the carb, then you shouldn't get issues and I have had none but I actually do very little cutting as all mine is for the log burner. I have had one or two saws in that have expired for no particular reason but the main cause of failure has been air leaks, bad fuel or incorrectly adjusted carbs. The "No reason" ones were probably dodgy pump fuel or just damn big bars and a tad to little oil but can't substantiate this. I do get saws motoring - I have seen the 357XP hit 15,000rpm, the 346XP do the same and 372XPs up to 14,500 - all ported but running on Stihl HP IMO, if you mix bang on 50:1 and cock up a little then you may have issues. if I cock up a little using 45:1, I am back on 50:1 I like the new Sugihara marketing, thought I had a virus when that banner came up!!!

Step away from the dremmel:001_rolleyes:

A Komatsu powered Allen, the trimmer was an Echo and the blower a BG85:thumbup: Just can't help myself:blushing:

MS441 has a weird ring end running up the side of the exhaust port - not much you can do about it. The strato design really limits the amount you can take off the inlet port on most of these saws,

Yup, and a hedge trimmer and blower:blushing:

Yup, Barrie is a top dude:thumbup:

Sorry bud, no need to throw the toys out of the basket:blushing: Blimey, won't mention it again:thumbdown:

Ask Rich about his 026:001_rolleyes: Not had any issues to date and some of mine have been out there a few years now. I do thake care in making sure that certain constraints are not breeched when porting. In reality, the bottom end of the saw is pretty over specified and will stand up to the extra power.

Correct - the switch is normally open and unlike "normal" switches that are normally closed to turn something on. It is possible the wire has chaffed and is earthing - you can disconnect the blu wire from the coil and try the spark again. Saws that have been flooded can take a bit of getting going again!

I know which side I will be on:thumbup: I quite like the thought of being a Viking - I gather we have nordic DNA in our family according to my old man - had his checked for such stuff:thumbup:

Ive got this image of a large field - with stihl wielding arb types at one end and Husky wielding at the other - running at each other in to battle bit like Braveheart on two stroke:lol:

Right, you have fuel, go back and try the spark again, make sure you get a nice fat spark, get an old plug, open the electrode right out say 3-4mm and pull it over hard and see if you still get a fat spark - if you don't, chances are the coil has failed. Other than this, the saw may have seized - try taking off the muffler and looking at the piston to make sure the piston isn't scored, You could also try a compression check if you can get hold of a gauge - any self respecting car mechanic wil have one but try the Gunson one if possible. An engine needs spark fuel and compression - life isn't quite that simple but it isn't far off in theory. If you have checked all the above - heat the plug up with a plumbers lamp and fit it back and pull it over with no decomp valve, no choke but DO use the fast idle setting (choke pulled out then pushed in) If that doesn't work - send it in:thumbup:

Whose the tubby fella in the vid:001_tt2: The saw is nice though, who ported it:thumbup1:

All good, the 254 is a classic and made Husqvarnas reputation, the 371is an early version of the 372, very similar in all respects, the 346 needs no introduction - a modern day 254 and worthy successor:thumbup:

On the 441, the stalling on idle will be the low speed adjustment and not hitting high revs is probably the carb being over rich - it will be worth pullig off the muffler and inspecting the piston to make sure it is OK as low compression can also inhibit the saw to make high revs.

Most likely the last fill, sounds like it may well be coming to me, it would have been an expensive mistake to have this happen again after repair - I will get it going if it can be salvaged and the route cause found if it is an air leak etc:thumbup:

Stevie B has to walk that line between his sponsors - thats the guys whose money goes to keeping this site alive and kicking .........and us, the unwashed joe public fanatics that make it what it is through our posts. I think his position often gets lost and for one, have no issues with the way he runs the site - it is a fine line to tread!

Think he does Matty, I think it may be chainsaws at dawn on this one - just make sure it isn't round here - I will get the blame for the noise:thumbdown:

Sounds like either the policy was found to be illegal or their sales fell off a cliff, we didn't see that one coming did we:001_rolleyes: Lets say goodbye to this arrogant policy:thumbup:

Yup, thats right, may have a ported 066 ready for a bash soon:thumbup:

Thanks Martin, this is my 357XP, I was pissed off that it got beaten by 0.4 seconds on three cuts by a 560XP running a shorter bar so we took 0.5mm of the outer Piston crown and cylinder base which upped the compression to 200psi. The saw already had widened ports and modified uppers and lowers plus a loud muffler mod. Goes rather well now - [ame] [/ame]
