You need a new thermocouple. This is a safety device which holds a small gas valve open when a flame is detected. It stops unburnt gas building up in the oven. I would seek professional advice from a gas safe registered engineer. Check www.gassafe.co.uk for an engineer in your area. Good Luck

Sounds like the pilot is mounted to far away from the burner. I have seen it happen before where the pilot has detached and the main burner will just keep pumping gas in until it hits the pilot flame and just flash flames and everything goes out.
Or it just could be a bad thermocouple that is going out all the time.
With the oven door open, watch the vents at the sides of the floor of the chamber for an orange glow a few seconds after you try to turn the oven on.
If it doesn't appear and is similar to other later ranges, it means the igniter has failed.
If built as others, it will have hot-surface igniters (one down, one up) and the lower one has failed.
To confirm that this does use the common system, air out the oven first then try the broiler.
If it works, you have gas available but nothing to ignite it.
Also, you should never get even a distinct thump; this could be dangerous and the gas should not flow without lighting for more than a few seconds.
The knob won't have any effect on the flame size. The knob controls temperature. If you're referring to the pilot light staying on and then the main flame not going on...that's another problem. If the main flame will not go on, the assembly that controls the main flame is likely defective. If the unit has a thermocouple, you might change it out first. Sometimes, that's all that is needed and they're cheap.
Zanes, Your oven igniter is getting weak. The glowing bar next to the manifold must draw between 2.7 and 3.3 amps before the safety valve will acknowledge that it's actually hot enough to ignite gas and open up. Your igniter is most likely right at ~2.5 amps and the valve is "wanting" to open, but won't without some persuasion (hammer anyone?).
The part number for your igniter is 9753108 and is available. Your local appliance parts house may not carry it, but there is a substitute that they WILL carry. Its' part number is WB2x9998. It's a universal flat igniter. Unplug the oven before repairing it, OK?
