Wow man that's the oldest glow starter I've seen in a while! You're probably better off getting one
like this as everyone's saying. The long version is good to have if you ever step up to a big-block engine at any point.
As you've probably figured out, this is why they call them "glow engines" - once the combustion begins, the interaction between the fuel and plug keeps it glowing hot enough to continue combustion. There's actually a fairly narrow band of conditions for this, and requires the correct fuel mixture, a good plug, and compression, search forum for "tuning."
Also some other great searches you may want to do are:
compression - if this engine is old, and run without a filter (see above, very important) you may have lost compression, this will reveal many threads on how to determine if your compression is still good
temperature - many discussions on how to check and how important it is, or is not
tuning, how to tune - Did I say this already?

Slight mistuning will give you all sorts of troubles, beginning with "can't start" (another good search)
servo - and why that SP-148 is not the best one for you
prime, priming - beginners tend to overprime their engines and IMHO is the most common reason for start problems
Last thing, also common - never try to start the engine wthout ALL ELECTRONICS ON. If you do, it may take off on you, always insure tyou have a signal going to the vehicle - and it's receiving it.
