Hi, I have a Stihl MS381 with an air leak somewhere.
The saw starts easily enough but revs high (about 3/4 throttle) and won't come down to idle.
A mightyvac would be useful but just for a 1 time use atm I cant justify the price.
I've ordered a hand held brake bleeder vacuum pump with a gauge.
My query is, if the saw won't hold vacuum, can I track the leak by vacuum alone? IE: Will it hiss, or bubble with soapy water etc?.
I guess I can remove the gauge and connect it to a foot pump to get a pressure test, but won't know till it gets here.
