Hey guys! New to the Mazda scene and i've already found myself in trouble!
1991 Mazda B2200 (Carb), 2nd Owner, Ive had it for about a year now no major issues.
Ill be doing 45 in 4th gear, and i get the surging/pulsing feeling in the truck. Power then no Power
If i BARELY push the gas it just wants to go! When i step on the throttle it wants to stumble on itself or it will just hit a flat spot (like a 009 on a VW)
I figured the timing might be off so i hit it with a timing gun, seemed to be fine. I pulled off the Vacuum Advance and the engine didnt change rhythm at all . . . its hooked up to my carb so i just ordered a vacuum advance. But my motor runs smoother when i pulled off the vacuum line that hooks up to the airbox where the 3 hardlines come from the exhaust??? sorry i dont know the correct terms. Replaced rotor, cap, wires, gaskets, fuel pump, coil. Compression is awesome and within 10 pounds of each other. I love this truck and would love to save it! Any help would be awesome! I'm in Phx, Arizona
