Have taken the carb off the chain saw looking for problems, but found none. Same with the fuel line. Does this model have some sort of fuel filter? I am doing this in a power mechanics high school class and am trying to troubleshoot why it won't start? Any ideas before I pull everything and can't get it back together?

Re: Echo 452VL chainsaw won't start
Yes it does.the filter is in the fuel tank on the end of fuel line.if it isn't the fuel line needs to be replaced and a new filter installed.there is most likely some of the fuel line in side the carb. there is a small filter inside and it usualy collects the broken fuel line there. take the carb apart oppiset of the diaphram.usualy it's the side with only one screw.carefully blow the **** from it and the saw will get fuel again and start

take side cover off and remove screws that hold the pump bulb in place and remove the gas lines make sure you put the right one back on each side.the one that sucks goes to carb. and other goes to gas tank.
Hello Gordon; We need the complete make, model, and serial numbers with every question in order to fully help you. The IPL for the DCS510-18 can be found on this page: http://www.makita.ca/index2.php?event=tool&id=361&catid=40 Fuel line routing while pictured isn't clear. In the US of A these are red and called Dolmars. A local dealer may allow you to look at his shop manual if one exists. Sorry to not be helpful. Lou
Hi, It does have a filter of sorts but is on the pickup inside the tank and should not need changed. Drain the fuel mixture and check all of the plastic lines and primer bulb for cracks or kinks. Put in a fresh fuel mixture that has not been sitting, (They don't run on old mix) and try starting again. The thought process is that if it starts on the starting fluid it can only be two things, old fuel or no fuel. If the fuel change doesn't work it is probably not getting fuel thru the carb, these oil mixes gum up rather quickly and if it sat for awhile with fuel in it it may need the carb cleaned. Good Luck to you, hope this Fixsya!
