anyone on the isle of wight had kit stolen?
spudulike replied to marc laycock's topic in General chat
All the MS200Ts have the flippy black and white fuel/oil caps - it is common to get hybrids made from parts or a later MS200 fuel tank fitted to the earlier 020T crank cases! -

A real difficult one as the saw may have spent years in use with the numbers off it and may never be reunited with the owner. It sounds lie an 020 if it has the black screw in fuel/oil caps and that dates it to pre 2000. You have broadcast it, go use it if no one claims it, not much else you can do with it...is there? -
Yeah - the travelling folk were still inside it:lol:
-
Thats a bit like "how long is a piece of string" - just adjust it like you normally would - wind it in until the idle picks up and peaks then wind it back out until it drops no more and the saw sort of pops unevenly - it shouldn't be out any more than 1&1/4 turns - takes a little experience but too far out the saw will be lumpy and smoke on idle qand when picking up, too far in and it will lack power and bog excessively when cold.
-
Is the saw fourstroking when revved flat out - I would set to manufactures standard settings and leave well alone. I would only retune if smoking excessively or lots of carbon is being formed!
-
The Cylinder may be salvageable - are the scores in to the plating or is it just transfer from seizing - get a pic up and let us see it:thumbup: If the cylinder can be saved, purchase a Meteor piston, clean the cylinder and rebuild it. If the cylinder is toast then the OEM part is best at around £150 or Tesgol on ebay has some decent aftermarket ones that should give you a working machine again. Make sure you correct the route cause for the initial problem.
-
Has it been modified in any way and is the carb the original?
-
The max manufactures revs are 13krpm What symptoms have you got, it may be rich on the L screw! It is the colour of the plug that is important at the end of the day and this is best taken after a number of big long cuts with no idle at the end!
-
Best pull the muffler off and take a look at the front side of the piston, vertical scores are bad news and if it looks like a wet fish belly, all is good. After pulling it over, is the plug wet - if it is and you have compression then the problem may well be spark. The 6 plug is a different heat plug, both will work but it should be the 7 plug for correct use. A running engine needs compression, fuel and spark, it is just making sure you have all three and if you have, then it is a case of a little more diagnosis!

MS341, taken apart to port, the first thing is the piston has a forward facing ring location pin (arrowed) leaving no room to open the exhaust port up so just took the carbon off it. The cylinder is open port and there was mee thinking it would be closed port:001_rolleyes: You can see the crankcase is flowed a little where the transfer ports end. The inlet was widened a bit, the base gasket can't be removed to decrease squish as the piston would clout the cylinder so opened up the gasket where it was impinging the transfer ports and opened up the piston windows. A muffler mod will be done soon.

Not sure where you are going with this one Rich, the ones I have done in this way, I guess you could do it with the fuel tank in place or strip the cylinder off the machine but the way I describe works fine for me....each man to his own as they say!
-
It's one thing having spares and another fitting the thing! OK if he is good with the tools but not so good if he needs another to do it! Possibly someone has tried to remove the clutch without realising it has a right hand thread!
-
I am in North Herts, just off the A1m, if you get totally knackered, you can send kit through the post using one of the courier services - usually £10 each way. One tip, bring the piston up to cover the exhaust port and stuff some tissue in the thing before drilling - it may get messy if you dont:blushing:
-
I have done a few now, as Rich says, try the stud extractor route and see if that works, don't break the extractor in the hole otherwise it will be a devil to remove being hardened. If the thread is bad then helicoils effect a good repair and if it gets really bad then I have used inserts to good effect - 8mm tapped hole and screw in. Got a few pictures on "whats on by bench" thread - it is best to remove the top handle and fuel tank to get to it!
-
Sometimes boiling the rubber in water softens and swells the pipe enough to form a seal!
-
I prefer mine in a white sauce......but back to the issue, are you sure the fuel is coming from the carb? Leaking fuel lines/tank connector, breather/vent, tank cap etc can cause fuel leaks but if it is coming out of the carb then a faulty needle valve/diaphragm/ metering arm may be causing the issues!
-
Not had one myself but try fitting a new pipe and if that doesn't do it, degrease all parts and use some "seal all" on the connection.
-
The top end mix can be a bit fat from the factory from new to let the piston bed in, your saws would be worth retuning IMO
-
How are you doing on this Morten? Anything found out yet?
-
Yet another MS200T in for a refurb and port - came in running but lacking power in the cut. Got most of the work done, carb has been thoroughly cleaned under heat and ultrasonics, done one fix that can stop issues and will see how it performs once back together. Also have a MS341....yes Rich, I know it is a Stihl:001_rolleyes: don't get too excited:lol: It is in for porting and a muffler mod. Squish is about as low as it should be from standard so no gain here. Construction is pretty standard - no strato ports etc so a fairly straight forward tune I hope - first one I have done - the muffler is sealed but reckon a large front exit pipe and enlarging the holes in the baffle plate will get it going a bit plus the porting will increase breathing a little!
-
Funny you should say that, I am broad shouldered:lol: Too busy go take the time go be insulted, Petes a brave man seeing that I have his long reach trimmer in at the moment.....what sort of box do you want all the bits put in to:001_tt2: The final bill depends on attitude, knocked a bit off Stubbys:thumbup: now Peters.....let me think.....
-
The loudest saw I have come across - the muffler was a real nice job, no intrnal baffles and two real big exits:thumbup: Cheers for the use of the log pile and your time Matty, got the job done! Reckon Stubbys would go faster with a nylon filter though:lol:
