Where are you pulling vac from? Can`t see in your vid, is the sparkplug in tight?
I bought the carb adapter flange from Stihl. It was the one that just blocked the carb boot. I plugged the impulse line up. I will have to check and see if the spark plug is tight.Where are you pulling vac from? Can`t see in your vid, is the sparkplug in tight?
When you changed tanks it acted up? Well check the fuel for water or contaminates. MikeI started cutting the logs down into firewood length it also ran great for a tank.
So you think mine is good as far as vac/pressure is concerned? I might replace the impulse line just to be sure its sealing against the carb good. I cleaned the carb before, even though it didnt look dirty.
Its not fuel. Brand new fuel, brand new oil, bone dry storage tank, Saw tank is clean.When you changed tanks it acted up? Well check the fuel for water or contaminates. Mike
I'm with Wood Doctor on this one...sounds like a carb problem. Hey just for giggles, try running your H and L needles all the way down until they seat (lightly) and then back out to their original settings. I have, on more than one occasion, had an old carburetor give me fits as gunk starts breaking loose in it (even after a cleaning....its really hard to get all the dried gunk out of every nook and cranny) and partially clogging the H and L needles causing an intermittent lean condition at idle (reving or high idle) and at full load (over-reving lean and or falling off of power). By running the needles all the way down you, effectively, push the dirt through the jet ports which clears them so fuel can flow proper. Works more often that one would imagine....definitely worth a try if you haven't already done so. Very easy to do. Only takes a few seconds! If this fixes it then great. If it keeps happening, I would definitely go buy a new carburetor for it...they're cheap!
My carb soak idea might work here also. Remove the carb and soak it submerged in mixed fuel inside an empty jar for about 36 hours with the lid on loosely. Then see if that makes a difference. Many times I have found that it does. Also, be sure that the fuel filer (pickup body) isn't blocked up. Replace that also.
I've never run an aftermarket carb, will they be good as well or stick with OEM?
