Oh & Spud,I have a spare 200t,very fresh,could you do a gentle porting job on it?

Well Not on my bench at the moment but hopefully will be very sooooon. Is my Ms200t the saw starts fine, but as soon as you open up the gas to it is very slow to get to maximum speed, while some times you have to0 back of the gas as she will just die. Once you turn her recoil up then she just die's completely...... Dont suppose any one has any ideas, im guessing carb?

Possibly crud in the gauze filter in the pumping section of the carb, an air leak or just the L screw is a little lean.

The MS200T has limitations to porting that are caused by the piston design and where the ring ends are, the exhaust port can be widened, there is little that can be done with the inlet port, the squish can be lowered and the muffler can be modded and that will give the saw more go.

 

Just PM me if you want me to tune the saw:thumbup:

Somedays things just don't go right and yesterday was one of those. I had a 12 yr old 017 brought in for service.

I could start it, but it would rev then die, so the "service" becomes a "repair"

 

Dissmantled carb and found the metering diaphragm and gasket in the wrong places and the metering valve spring missing. Some one has been here before, methinks.

 

Cleaned the carb, fitted new carb kit and spring. Still the same problem, so dissmantle and clean again, reset metering arm, pressure test and refit, Still the same.

 

By now getting a little peeved, test compression, a bit low at 125' but should work.

 

Now, this saws not worth much, so phone customer and tell him sorry, cant fix without spending loads more time and money, poss need pressure/vac test on crankcase, poss need new carb. He says he will think about over weekend.

 

Anyway, today I decided to whip carb off again, and put in sonic cleaner for 45 minutes, the buzzing was driving me crazy, but when I reassembled it to the saw it started up a treat and worked well.

 

As they say "if at first you dont succeed, try, try, again"

The customer is very pleased.

Nice one Barrie - think we have all had one of those types of saws!

 

My weekend - the good news is the 357 runs like a screaming banshee - tached it to 14400 and hit some wood and it rips through it and it only has a semi chisel on it, will do a vid once I have some time.

 

The 365 was tached and runs nicely but the 254 I am doing is being a pig on a warm start - thats life!

What sort of frequency do these sonic cleaners run at?

I was wondering if I could set up a little makeshift one by taping an old speaker to a little tub full of white spirit or something? I've aquired a 2nd hand carb that looks a bit cruddy, got a new carb kit for it but would like to make sure it's all clean first and no time to visit a saw-shop.

 

Do these thing run on old-school reggae ok, or would a bit of folk-rock be better?

Haha, great idea, music while you work! it would have to be reggae, non stop.

 

Seriously though, it would have to be pretty high requency to achieve the results. I just looked on my Ultrawave machine and it does not give any hint as to frequency. It does however work with a high pitch buzz which drives me crazy. I much prefer to listen to Suzy Quattro.
