Your burner assemble/combustion chamber is dirty
*Remove the burner tube--------clean using small bottle brush
*Remove the spark electrode from combustion chamber---clean using some emery/crocus cloth and wipe down ceramic with a silicone on a rag
*Remove main orifice from as valve-----soak in alcohol and then blow it dry (no poking things thru orifice)
*Run a wire thru combustion chamber out exhaust, tie a rag to wire and pull back thru 'U' tube
Reassemble.....
Clean/tight connections
Fire off and adjust air shuttle (loosen screw while burner tube is out) so Flame is Blue with tingles of orange at tips-----spark electrode engulfed in flame
