Yes I try to look into fuel tank, see what is on the bottom, and drain it into a big pickle jar with a syphon.....if it's bad drain carb. This one needed a tuneup as it wasn't getting full revs or cutting properly. Sorted out the blade plate....... Fiddled with the springs on the B&S 375, got it revving a bit better. Topped up the old, cleaned the air filter.. They only wanted a $25 service and that's what they got. cheers speedy
