66cc 76cc too. cost more on this site but can see them all  http://www.myshopping.com.au/ZM--1278739140_Baumr_AG_92cc_Petrol_Commercial_Chainsaw_24_Bar_Chain_Saw_Pruning_E_Start
Most of the rest of those are variations of the Zenoah G621 design.  This is clearly not.

Na its a beast in its own right appears to be a reed valve engine the induction system is excessable by removing a perforated cover under the saw their really no need to remove the top shroud as removing the top shroud means removing the starter housing 3 screws and 3 more to git the top shoud off not hard i'll post some some pics of the bar mount it's possibly stihl or huskie i'd say

It has a stand alone cylinder with the induction side all mounted on the crankcase that's why i'm saying reed valve

So before most of you fellas start knocking something you know nothing about give me a bit more time to sus this thing out as the saw appears to reasonably solid in its build nothing like the smaller **** saws I have seen around

Access to the high and low mixture screws is through the rear handle and has a rubber guide to aid in locating these screws and it least the screw driver won't slip off during tuning and the screws are well marked for high and low.

In the video of the fella removing the top shroud he has to remove the starter assy as theres a stepped mound on that attachment point for the chainbrake pivot that's holding the top cover in place.
Plus you will need to pop the fuel line off don't forget to empty the fuel tank first.

video says = Baumr-ag SX92 in action. First cuts
PLEASE READ THIS. 2 cuts after this video the saw started 4 stoking (running rough like on half a clylinder) took the spark plug out and it was fouled(covered in oil).So i turned the high screw in 1/4 a turn (clockwise for those who don't know) and replaced the chineses plug with NGK. Saw is now running at full strength and how a 92cc saw should run also it started idling high so turned the low idle screw out until the idle came down which was only about 1/8 of a turn.I have used alot of saws and this one has impressed so far.Now its just how long will it last.I'm sure it will be fine. LOL




Same as any other saw regardless once their broken in they need retuning
