  • hesitating engine

    hello guys i am new to here.

    i want to start whit a littel problem that is bothering me from a while now.

    my car has a 1.3 sohc 16 valve carbed b3 engine like the one found in mazdas 323.

    the problem is that when i drive and press the gas pedal when the revs reach 3.5 k the engine hesitates for a coupel of seconds before continuing to rev up.

    when i realease the gas pedal the revs doesnt go down imidiatly but the engine stays reved up for a second before revs go down again. this happends when the revs get over the 4k mark.

    somethimes after a good reve the engine even stalls and goes of and no matter how i try to get it back on it continues to shut of when i let go the gas pedal. to sort this problem i have to give it a good rev to about 5krpm and then it stabilizes.

    so what i have tried now is new leads, new plugs, and new distributor head.

    it think the problem is from the carb?

    sounds like a vacuum leak. Could be in the carb, the carb base gasket, vacuum lines, or manifold gasket.
