After fitting a new timing side bush and re building the engine she fired up today. As others have said, it always takes some time to get started after a re build, but finally burst into life. I can hear the neighbours saying Oh no not him again is it that time of year.
As it always takes a long time to get the oil to return to the tank I earlier decided to prime it. I removed the plugs and the relief valve and turned the engine over with the kick start. I then left it for about 10 mins. I did this three or four times until I got oil coming out of the relief valve hole. Even though, it still took a while to get the oil coming back to tank.
One or two things to do and then roll on summer.
