Good morning just about to start restoring my Lister Junior .When I bought it the fuel pump wasn`t working ,but after fitting new string seal it seems Ok. However when I removed the fuel pump ,the operating lever dropped down. If I lift and hold it up and turning the flywheel , nothing happens to the lever ,I expected it to go up and down .May something have come adrift inside the plate it projects out of .If so since this plate holds gears ,I think for the tappets is there any thing I should be careful of removing it. You can see from the photo when I turn the flywheel ,without touching the piston lever ,it drops to downwards Len
