Hi Ted12 Only spend the bare minimum to get it going then decide what you are going to do with it. If it looks like being expensive to get it going keep it for spares and move onto the next one, they aren't worth much even in good running condition ( unless you can convince someone it's an SB 45 ) Don't worry about the filter cap til you have it going and your happy with it, if the spark plug has a decent spark don't replace it. Not sure what you mean by sloppy in the port, was it finger tight or does the thread in the head look damaged, the plugs don't need a lot of tension when tightening, its Alloy. They have a decompression valve so you wont feel full compression when you pull it over. If you take the valve off and fit the spark plug into the hole then put your finger over the spark plug hole there should be a heap of compression when you wind it over. The head bolt in the picture doesn't look right which indicates someone has had a go at something. Cheers wce
