Actually you don’t get one with Sierra kits! Not the ones I am looking at anyway? The BRP kits come with two (one with each set of points). The original oiler felts have just about deteriorated away in most engines you open now days from the 50s & 60s. Don’t see why the same thing would not happen to something from a material shop? Buying a tuneup kit is the cheapest way to get everything you need.
