Yeah, it is your mate Jon.....Mendiplogs:lol:
-
It is the backbone of the sort of work I usually end up with. Saws others have written off that I bring back to life....bit like Lazurus:thumbup: Normal allen keys may shift it, the two long bolts tend to get pretty locked up, stick some WD40 on the heads overnight and see if it loosens them up, a tap from a hammer may help also!
-
Either measure the compression or pop the exhaust off and take a look at the piston through the exhaust port. It is possible it has had a seize and is now lacking compression hence the failure to start. You will need to remove the bar and chain to get the muffler off as the support bracket slides in behind the felling dog and is held in place with two bolts as well as the main two that go in to the cylinder. Let us know how you get on!
-
That all sounds fine then, I don't see any risks with that setup!

Check you have spark, from what you say, it has compression. Is the plug wet after you pull the saw over with the choke on? If not, check the metering arm height and if it is very wet, it may be the needle valve is leaking or the gaskets in the carb are not fitted in the correct order. Worth checking the state of the HT cable, a spark plug with the end electrode bent out at a 45 deg angle makes a cheap spark strength tester! If this doesn't work, get hold of the IPL and check the coil and flywheel part numbers and make sure they are correct to the machine. If this doesn't work....send it to me:sneaky2: and I will stick it on my thread and embarrass your woeful attempts at getting it going:001_tt2:

It is just a MS660 with a smaller bore, same build, pretty much the same saw. There was an aluminium company in the midlands using them to cut aluminium billets and these ones were generally shagged but if you know the history then all is good.
-
No, the faults I have seen are just design with perhaps infrequent use not helping!
-
I would say that the partition is just to give the airflow a linear direction rather than letting it swirl in the elbow as the manifold also has a similar partition and this guides the fuel vapour and lower air to the actual inlet port and the upper part is very light on fuel vapour and this is used to load the upper part of the transfers via piston porting. Will it cause an issue - unlikely it will effect performance, more likely it may effect how much fuel vapour is expelled with the exhaust gases which the strato system is designed to clean up. Just make sure the saw is not over revving!
-
You have ignition timing set by the flywheel magnet position, the flywheel key, the crankshaft and the coil. You also have port timing which is set by the position and height of the cylinder and the dimensions of the piston. If the correct parts are used, the ignition timing can be knocked out by a broken flywheel key or a coil failing. The timing of the cylinder can't be changed without grinding out metal or changing base gasket height. It is more probably that the carb has been rebuilt incorrectly or there is another fundamental error with the rebuild.

It seems all the 088/880s I have had in recently have had dodgy oilers. The usual culprits are oiler arms not gripping the pinion and the gears in the oil pump wearing!
-
Glad you are still enjoying it, that was a clean saw and a long while ago!
-
One of the reasons I know is I fitted a Chinese P&C once and the ring snagged on the poor bevelling around the exhaust part!
-
The 441 has a ring that ends just off the exhaust port stopping it being widened, can't recall if it is the top or bottom one as sometimes you can drop the lower ring to overcome this sort of issue - got one in at the moment, may take a look:sneaky2: The 372XP (pre xtorq) and 357XP that Joe is talking about are superb saws for porting.
-
Checked the IPLs and both saws share the same air filter elbow - 515 98 29-01. Not sure where you are getting your info from???
-
In light of that - a tach tune to 500rpm below max spec may be wise to make sure the mod doesn't screw with the max revs!
-
This is all part of the Strato system so leave it in place and just do the transfer covers!
-
Probably going to be fuel related, the fuel filter position sounds like a good suggestion. If the engine is running rich then fuel and oil can build up in the engine only to swamp the plug when vertical. If it is under warranty, take it back. Echo kit is generally pretty well made and well thought of.....says he with a long reach and 1m trimmer in his personal collection!
-
Tell you what, give me your £300 and I will send you nothing coz that is what will happen if you buy one of these! And if you get anything, it will be a copy but have only seen the old version 372XP....it was good, a bit like a real one but just not right! The chance of you getting a real saw.......ZERO! Save your cash.

MS200 - 13500 - 13800rpm MS460 - 13200rpm 390XP - 12800rpm I usually tune a modded saw to a little under maximum specified revs, this is usually so they don't come back fried in six months. You can hear the four-stroking on modded saws more easily then standard ones!
-
Personally you should do yourself a favour and split it for parts!
-
I use one like this.....

What do you lads get up to when the wife pops out??

Well mine came home once, said "what's that smell", went in the kitchen, opened the oven and pulled out a set of re-painted 066 crankcases:blushing: .......oh bugger:thumbdown:
