Hi this is usually dried ames in the side walls at the top of the taper - maybe worth undoing the head plate and just checking to see if its all clean and of course straight in the tape feeder - if it is then it;s a head scratcher - let me know what you see when you open it up

I solved my own problem by fitting a new clicker pin. The bazooka had stopped making that rasping zip type noise when running a tape and the piston was slipping down allowing air inside the tube anytime i laid it down resulting in having to wind it back up continually.

Belmore may be right but the pin is worth checking.

hi thanks for your reply,i always take the head plate of when I clean my gun out,its so frustrating,the first 6 inches have cement behind the tape then the next 10 inches are dry then the remaining length of the tape has cement behind it

had this problem on a variety of guns over the years,at the moment using a brand new columbia gun bought a few months back and thats doing the same.know what your saying ames and that would cause it but the cog is not running back at all.ive tried winding on by hand b4 starting,i run it on at the end of the previous run,but problems still there.take the plate of after every use marcus and hose out,no difference,tried adjusting the tightness of the cog which u can do with columbia,no difference.
watched a video of a gun getting stripped down on you tube and im wondering if it could be the clutch spring that needs adjusted,been to scared to tinker with it,would that make any sense marcus.

Could be your pump. If there is cement on the first 6" then blank tape maybe your pump is drawing in air.

defo not the pump drywall,its at the start of every run,know exactly where the dry spot will be ,if it was the pump the dry spots would be random,cheers anyway.im not getting 10 inch dry spots like glens,more like 2 or 3 inches.

tricky to diagnose without actually seeing the taper - does it sometimes go stiff (oh er mrs) when cable is pulling up the plunger up on a run? this is usually a culprit for a "kink" in the tube underneath the strap bands on the taper body, this can cause uneven plunger movement which will result in dry paper. or you have some sort of issue with air in the taper - maybe take a look at plunger cup see if its worn out

dont know about glens marcus but my gun runs as smooth as,plunger cup is fine,gun is only months old and its been doing it from day 1,i know exactly where the dry spots are going to be every time which is why im thinking along the lines of the clutch.
