oh yea, they are pinned in, just need some pliers:)

shocks is easy, one Nut top and bottom replace bushes and bolt back. 15 minutes. only need the approriate spanner for the nut. Head lights are reasonably cheap, so maybe just change them than argue? keep the old ones as spare.

My inline filter always has air in it, normally only about a quarter fill. You could pull the fuel line out of the carb and pump the fuel pump manually, would be a guess from there, but you could make a guess to wether or not there is another fuel being pumped. Sounds like you are saying that it...

I dont think you should have air in the glass bowl, check that the seal around the top of the glass bowl is sealing correctly. Remove the bowl and check the seal that mates it to under the fuel pump. If that seal is damaged or not seated properly the pump will suck air in from that gap. Hope...
