1994 Briggs/Stratton 16HP Twin II (Runs but won't stay running)
Asked Jun 24, 2010, 05:27 AM
This motor is on a 1994 Murray riding mower. The initial problem started last year when I lost spark in 1 cylinder. I replaced the coil, regained spark in both cylinders. But now this season, it will only run if gas is poured into carburetor, it seems to have vacuum but carb won't pull gas through. I replaced the diaphram, springs but none of this helped. The gas is pouring into the engine oil, it seems to be making oil. Is this a sign of an internal problem? I am completely stumped at this point and any help would be appreciated. If the engine is shot, I don't want to keep throwing money at it.
