Manual gas pump sticking and oil in new Tygon tubing.
This is a two part query with the first being, my Hangar 9 Ultra manual gas pump works well but if unused for a few weeks is very difficult to crank initially when put back in use. Why is this and how can I stop it from happening as it puts quite a strain on the cranking handle which I am afraid will break one of thes days. I use a similar pump for glow and it works perfectly.
Secondly, some time ago I bought some Tygon tubing and put it away in a plastic Zip lock bag for future use, and now on opening the packet I noticed the tubing was oily on the outside and had droplets of an oil looking substance inside. How could this be as it was all clean and dry when put away. It's a mystery to me.
