Welding off the Lister
ajaffa1:
Hi Mike. Yes I know that one, Australia is famous for mud wasps that will build a nest in just about any orifice that isn`t moving or covered! Very dangerous on the electric hot water cylinders we use here, they have a pressure relief valve, with a blow off pipe, in case the system overheats. Mud wasps and ants love to build nests in the pipe. I found that shortening the copper pipe and adding 300mm of polythene pipe at the end seems to deter them.
Most of my extensive collection of garden power tools are items that I acquired for nothing because they wouldn`t start or run properly.
I also have quite a collection of petrol water pumps most of which have been underwater in various flooding events. Trying to get sand and gravel out of the exhaust pipe, air filter, inlet/exhaust valves and cooling fans can be quite a challenge.
Another one to look out for on 2 stroke engines is the spark eliminator gauze on the exhaust. Some manufacturers recommend running a 25 to 1 mixture of petrol and oil, this is too rich in oil and it quickly clogs the gauze causing the engine to stall. I tend to run all 2 stroke engines on 35 to 1. More than enough lubrication without the problem of having blocked exhausts and 5 different oil/fuel mixture cans in the shed. :)
