Engine Performance problem
1991 Mazda b2200 4 cyl Two Wheel Drive Manual 275000 miles
After I had put a new head gasket on my Mazda B2200, the motor is now shaking and would not tune up. I tried to adjust the distrutor (timing) but does not make any difference. When I accelarate I can hear breaking sputters from the muffler. Where have I gone wrong. I am not a mechanic but do understand how a motor works. Any help will be appreciated.
