Ron;
I found that my desoldering bulb worked better after I drilled out the tip, the reason I drilled it out was so that I could clear blockages with a finishing nail. However the rubber bulb on it went bad so I'm gone to using one of those spring loaded solder suckers, it also works but the tip is worn out, but it's much easier to clean out though.
Regards
Arran
