We overhauled our wheel loader, new sleeves and pistons. We needed to time fuel pump but the decal on cover is long gone. we set 31 degrees BTDC and got it to start then moved fuel pump so it runs fairly well but engine still has a lot of white smoke and stops after running 3 or 4 minutes. Is tis a fuel problem or a timing problem
I found out the push rod on number 3 cylinder exhust valve was tight so I reset them all and now it runs fine
