How do you adjust the fuel air mixture?
hello sir,, now there are two types of carb.adjustment screw covers,the old one where there are plastic over the screws,simple remove the plastic covers with a pair of needle nose pliers or cutting off,,,second are the new ones that are above the adjustment screws,which you have to take your drummel tool with the cutting blade and cut slots in the screws, after you get this done it is important to count the number of rotations in until stops make note how many. because you are going to reset the same way.now remove the screws,put to the side when you get ready to put screws in put in all the way than back out as many turns that you noted, now that is factory set there should only be a small adjustment to do. the rule of thumb is turn both out 1 1/4 turn and adjust in until saw runs smooth and idles ok, it is hard to adjust the top speed when saw is running wide open,let saw idle when adjusting top speed is easier that way, when you go to cut wood you may have to readjust top speed, the above does apply some what if you are not using fresh gas mix and dumped out the old fuel and starting with fresh,and a new plug CJ8Y,and as you know the saw has to breath in and out by this i mean a clean air filter,make sure the small screen on the muffler is not cloged,this will keep saw from running at peak speed and sawing wood, ok i have ran across a few saws to where the small screen in the muffler is cloged so the saw would idle but not run at high rpm's,if you do and check all of the above your saw should run,oh btw check compression should be above 60 to 160 lbs, hope this helps,any comments welcome,thank you. 00
