Thanks Andy - always a pleasure:thumbup:

I have had a steady stream of MS200Ts coming since the MS201 came out, a dealer will be hampered with higher overheads making it expensive for a complete clean, inspect and overhaul but smaller workshops like Riches and mine can do this sort of job with no issues. Done many refurbs/porting jobs and find as long as you do a decent job on testing the vac/pressure/comp etc and have the facillity of sorting the carb issues out then the owner ends up with a decent running saw that will have a decent extended life! I have had a few right offs that have been brought back to life and IMO, for the cost I charge, it is well worth it and seems the opinion of many guys on here!

All sounds interesting:thumbup: The standard mufflers look like they have a nice big outlet to start with! Be interesting to see what one would do!

Lots of things you may not do on a standard saw that you may need to actually cut a bit of wood with for any length of time - just think of really going mad with compression, transfer shape, port size, muffler and carb mods - ignition to rip your arm off etc

The 116 isn't a bad saw, be interesting to do that - 60cc saw and not bad TBH. Even a good one won't be worth much over £120 There are a few trick things that would make for an interesting saw that you may not do as part of a normal mod - be interesting to see what it could do.

If it is a decent size one - port it:thumbup: Another plan is to port a 114 I have and take it to destruction or glory:lol:

But Rich, you have forgotten the 262, 254, 346, 266, 357, 395, 3120, 550, 560.......... I hate not doing the FULL job on an MS200, did one where the owner just wanted one issue sorted and it came back a week later with a carb issue, a clutch spring was broken and the starter handle came off in my hand:001_rolleyes: All would have been sorted on my full rebuild service:thumbup: Personally I find them pretty easy now, first one was a baptism of fire but after that - simple....but I have done one or two now:lol:

Ah:lol: theres a thing - the world and his wife of experts say "richen up the saw or it will seize" - in reality, you are pulling a heck of a lot more air through the carb - anyone who knows about the venturi effect will know that this actually has the effect of naturally pulling more fuel thorough the jets so the carb actually needs leaning off. I have done saws that run at 15,000rpm and are on a tad over 1/2 a turn - 3/4s is quite common on what I do. The telling sign is the plug - generally at these settings it is still deep brown and not the bleached white it would be on a standard saw. There you go - if you don't agree then you probably don't actually know what you are talking about:001_tt2:

Jeez, it is like the M25 at rush hour:lol:

026 carbs are the bane of my life....even after cleaning:001_rolleyes: Worth doing but they seem to suffer from the idle speed being a bit intermittent - reckon it may be from wear in the L screw seat as I found no other fault with these carbs! Ticket to get a saw repaired - do you need a driving licence to get a car repaired and what about home user saws?????

Well, the 028 is a bit long in the tooth but the 350 and 357 are not that heavy so would be pretty good for general purpose saws - if you want a bit lighter then a 346XP or 550XP would do it.

Know what you mean - I am usually laughing my head off when I crack a joke and everyone is standing around scratching their heads....Phillistines:lol:

Rich, my sides are splitting with your mirth....and you can't spell cuckoo:blushing: Apart from that, you should be on stage.....with no audience though:lol:

Whats on the bench - the Mother in Laws clock - made the mistake of offering to find one a year ago - Ansonia - around 100 years old pendulum mantle piece clock. I had taken the movement out and given it a poke clean and a bit of oil but it kept stopping before chiming so stuffed it in the US cleaner tonight and then used the compressor on it, oiled it, used the compressor on it again and then was a bit more careful with the oil. Seems OK for now but with these things - time will tell:thumbup: The 372XP still sits there waiting for a porting job:001_rolleyes:

Yup - got another 372XP up for porting and a Jonnie awaiting a possible top end so bear with me:thumbup:

Agree Barrie - I hate it when saws I have done fail out in the field, I aim for 100% success and take it personally if the saw plays up after fixing it! I guess it is how you get it sorted again and the fact you ARE bothered that shows your dedication!

That saw is a beast Andy - the funny thing is that my next door neighbour had a complaint about using his saw the same day as I was testing yours - think the guy was a bit anxious about approaching me holding that thing:lol:

Thats one good looking bit of kit - if I just had the time!! My best suggestion is stick to a motocrosser engine for a wide powerband and the power band in line with a typical chainsaw - 8-9krpm. A race engine peaking at 16K will have a narrow powerband and be hard to keep on the boil! Old aircooled will save the tubing and rad on a watercooled but you will lose the powervalve and a lot of power!

Lack of running when hot may be a number of things - fuel related issues a possibility as Alec has said. Compression is also a candidate - as a saw gets hot, the compression drops and can make a hot saw difficult to start if not impossible - you would also suffer a bit of bogging - it is worth popping off the muffler and looking at the piston through the exhaust port - any vertical scoring to the piston and it may be toast. Air leak - possible but generally will cause idleing issues and the revs won't drop back to idle after a high speed run as symptoms - a total seizure is possible if the air leak is bad enough. It may just be your carb needs adjustment if some little monkey has been busy with a screw driver:001_rolleyes: The 441 has a strato engine so the carb is a bit complex compared to many - it may just need a good clean in a US bath - I have seen the seal on the welch plug break down and then enter the jets intermittently causing issues! Food for thought - let us know how you get on.

Been porting a 346XP - started as a simple enough job but had a massive air leak - stripped out the flywheel and clutch - seals were OK so stripped it down again and found the inlet boot has been modified for the metal retaining clip but the plastic clip hadn't been clipped back enough so the metal clip wasn't clamping the boot properly. All back together and running - just needs tach tuning now a black unlimited coil has been fitted!

Back to the weekends exploits - Stihl back pack blower - bit iffy - decent compression, checked the piston and then cleaned the carb, oiled the throttle cable, ran it up and adjusted the carb all good:thumbup:

Well Alec - I think you have made us all feel a bit inadequate with the length of that thing - is it used to fell trees in next door but ones garden from your own property!

So true - had a nice Steak pie tonight with mash and cabbage - what a life:thumbup:

Now I am liking that idea, think you would look good in a chefs hat:lol:
