Thetbone 48 #1 Posted Monday at 03:00 PM My 1993 520H when I start it with the air cleaner on it takes about 10 minutes, very hard. I take the air cleaner off, so the cover and air cleaner removed, she starts right up? Thoughts? I'm confused. Share this post Link to post Share on other sites
lynnmor 7,607 #2 Posted Monday at 03:52 PM (edited) The air cleaner should have nothing to do with it unless it is installed in a way that is jamming the choke. Cranking for 10 minutes is a very good way to destroy a very expensive starter and shorten the life of the battery. Find the problem and quit wasting the parts mentioned. All of my 520's start the same way; 1/4 throttle, full choke then crank a bit till it fires, then push choke off. If it begins to die I will give the choke a quick jab on and off. If you have a weak fuel pump replace it. If the pulse hose to the pump is spent replace that. If you are not getting a good flow to the pump, clean or replace those things. If you have a vacuum leak, repair that. If the carburetor is dirty inside, clean it. Edited Monday at 04:09 PM by lynnmor 2 Share this post Link to post Share on other sites
