MS192 Exhaust Mod

As some will know i have a 192t with a modded exhaust. After getting a request to show how it was done, here goes;

This mod is just the exhaust that has been opened up, not the cleanest job but was done when the saw was new nearly 5 years ago, and has had very regular use since with no ill effects.

First of all i removed the deflector screen behind the side panel, there is a spark arrestor beneath this, that went straight in the bin!

Behind the spark screen is a recessed, rectangle shape with the exhaust hole in it. The back of the recessed part needs to be cut completely out, to look something like this;

I did this by drilling as many holes as possible in the rear plate(approx 5-6mm drill), then filing the excess metal out with a 5/32" file. It is much safer to remove the exhaust prior to doing this to prevent dropping filings into the exhaust port.

I did refit my deflector screen, but it can be left off if you accept the side cover of the saw may melt! Another option is to open the slot in the deflector slightly to allow more gas out, but here is mine standard fitted;

Following this, you MUST re-set the jets on the carb. This is best done with the aid of a tacho to get it spot on.

This is a quick and easy operation to do if you have a medium mechanical knowledge, but resetting jets is a MUST!

Hope this helps anyone with a 192t(or back handle) who wants almost the same power as from a stock 200.

Nice one.

Good stuff, is it much louder?

Many thanks Carl.

You might find that you will need to use ear defenders, and even need to put more fuel in it, but as a result it will have more power. i.e. it will cut wood quicker:001_tongue:

Im getting a brand new 192t sent over from Germany soon!

What do you change the carb settings to from standard?

Good question, theres no real definate answer as it depends how far open the outlet ends up, if you refit the deflector etc, but it could be as little as a quarter turn further out on the hi jet. The low jet may not need much adjustment.

These are only estimates and really to get it right you need to reset the jets with the tacho, as a saw running too lean after being opened up will not last too long!

Cheers, Pete.

Both my 020Ts have exhaust mods, one, my main saw ,also has polished inlet and outlet ports, the carbs are set slightly richer, I did not use a tacho I just tuned them by ear.

They are very responsive, cut fast but are not really that loud.

Ok then all you avid 192 owners, any of you going to give it a go:confused1:

I did think of you when i posted that Bob, I do know you arent a fan of any modded saws, but is there any particular reason?

Just curious really:sneaky2:
