But it is true Muffler can explode because of existence of the rest of gas throw away which not yet burnt in room burn and burnt in Muffler. Hence bursting the remains fuel in Muffler is so that heard by its eruption of this eruption happened at the (time) of you discharge gas pedal.
To avoid happened eruption like this it is better you do tune-up with important point inform to mechanic that you hear eruption. Good mechanic surely will do carburetor around tune-up and ignition system.
Arrangement at carburettor needed to fuel mixture and perfect air, though do not one hundred perfect % but surely will lessen the happening of external combustion. Considering vehicle age and its component.
Arrangement at ignition system cover tuning of timing (by turning around distributor assisted by means of ... timing-light) searching correct timing as according to machine specification. Do not forget also pay attention the condition of spark plug and tune gap (gap) be snugly.
Sometimes tuning of valve is also needed in this problem. Cause here gasoline fuel entrance.
Don't be hard wrong of this picture… make you which is this know of its name of thrower flame, there is special appliance which transplanted by at attributed to Muffler example system is switch, by exploiting the rest of gas throw away.. but there are some kit which peculiarly enhance gasoline so that yielded fire can be longer and more “Scrub”
