Ok folks I have an early 70's Satoh 650g Bison with the 4 cylinder Mazda engine. I had to put new plugs, plug wires, new carburetor, new rotor bug, coil, all the normal stuff on an engine that's set for a year or so. My owners manual tells me to set the crank timing at 16 BTDC and aim the rotor bug at 1 in the distributor. This is NOT my first rodeo, all I can get it to do is back fire through the carburetor...........What gives?...I have brought the #1 up countless times to confirm I am on the compression stroke for setting the distributor.................I am assuming the #1 cylinder on these Mazda 4 bangers is up front, or by chance could the #1 be at the back of the motor?............Why is it not trying to start???...Carburetor backfiring is the clue, help me understand the issue please......I ain't got no more hair left to pull out...lol
