Caulking gun problems

[princesskilljoy]

I’m currently trying to use a caulk gun and Selleys silicone caulk to temporarily patch a gap in my external apartment wall.  I have purchased the cheapest caulk gun at Bunnings and the Selleys Light Speed Caulking gun.  The first gun managed to dispense a small amount of caulk but no longer seems to do it.  The rod seems to advance normally while there is no caulk tube but doesn’t seem to manage to do it when I load the tube back in.  The Selleys gun does not seem to be advancing when I press the trigger.   I really don’t want to have to purchase a third gun, does anyone have any ideas?

I don't mean to sound like IT with the old "Have you tried restarting it?" but unless you've got 2 faulty guns, the only thing I can think of is a) the cap of the tube hasn't be cut at all or enough You should see a full open circle once cut), or b) there's a block in the nozzle. Have you checked these things?

I have tried trimming the nozzle further, taking the nozzle off completely, and opening a new tube of caulk.  At this point I'm not really sure what else I can do.

I'd just take it all back to Bunnings (with receipts) - they'll either help/fix it, or they'll replace it.
