Home furnace timing question

I just moved into a house that I bought, and the heater makes this 700 square-foot house nice and toasty, but the timing seems off. First something comes on, it makes a humming, sounds like a motor, but no air is coming out yet....that goes on for a minute or two, then the igniter clicks on and glows for about a minute, then flames come on for 3-5 minutes, then the fan comes on and blows heat up throughout the house.

The inspector said it has a timing issue....is this the case, what is likely the problem, and is this an expensive fix...?
Also, is this that big of a deal? It would seem, for fuel conservation purposes, not to be very efficient to have the flames on for a few minutes with no fan blowing...because once it blows it does so for only a few minutes before tripping the thermostat and shutting off...
i'm just trying to get a handle on how much it might cost to get this thing timed right.
the heater is a 1994 Fraser-Johnston.
