Need a part for craftsman snowblower

Engine #422707-1522-01 Overhaul rebuild kit #694056 There are a few parts in the overhaul kit that I am unsure where they go, the parts diagram I used does not show where a small copper colored washer and small teal colored sponge-like filter go. [ATTACH]11760[/ATTACH][ATTACH]11761[/ATTACH] [URL="http://jhemrick.blogspot.com/2013/04/step-by-step-how-to-assemble-fuel-pump.html"]I put together a step by step guide on my blog[/URL], but again, I don't know if the first few steps are correct. If you guys could give it a run through and make sure I'm doing it correct I would GREATLY appreciate it! Thanks in advance.

Hey guys I have a Briggs and Strattton 28M707 on my ride on mower. All was fine last time I used it and next time I went to start it, it refuses to fire up. It turns over and there is fuel going into carb. I took the HT lead off and I am not getting a spark. I disconnected what I think is the kill wire and still no spark. To give a little background the ignition switch does not work, I have to bypass the switch and have done for a long time, it is also kept outside under a tarp as I have no room to store it inside. Growing season is here and I have nearly an acre of grass to cut very soon and am desperate to get this running again. I am suspecting it is something to do with an ignition module or coil or something similar? There is a square aluminium box mounted on the engine with two wires coming out of it, it is filled with a clear/yellow epoxy. Would I be correct in assuming this is what give the spark? It is on a Westwood T1300 ride on mower if that helps. To let you know my skill level I am fairly capable with my hands as I am an electrical engineer to trade and have been repairing machinery all my life in factories. Everything from compressors to vacuum pumps to cnc machines to refrigeration and air-con. Any help in getting this engine going would be very much appreciated thanks in advance
