The 009s tend to not be of very good quality. They also don't have an advance curve that is very well matched to the needs of a Type IV engine. Well, most type IV engines. (John's seems to do well with it, and there are a couple of others, but they are definitely the exceptions!)

If you can find a shop that still has an old distributor machine and knows how to use it, they can re-curve the 009 for you. But it's not that easy to know what the advance "should" be at various RPMs, so either someone has to guess or you have to spend a lot of time on the dyno playing with it.

It is usually less expensive to buy a distributor that is known to work pretty well with engines similar to yours.
