[Solved] craftsman eager-1 leaf chipper/vac starting problem [PHOTOS]
Yesterday I took it out and could not start it. Fresh oil and fuel were used (I dumped oil and let it run dry before storage every year after I finish leaf cleaning around this time). Base on what I know, the engine needs air, fuel, and sparks to function and I know the spark plug, fuel/carburetor, and air filter are all good (just replaced those last year), so I started to wonder if somehow maybe the prime bulb is going bad and not getting fuel into the bowl or the ignition coil or kill switch is not working properly.
I noticed there were two wires that are not connected anywhere (broken!)
One of those two wires is a green wire coming out of underneath the fly wheel, according to the photo I took from 2009:
It looks like the green wire should connect to the ground on the chassis.
There is also a black, plastic kill switch for safety at the rear leaf outlet / bag contact area:
Normally the engine only runs if the metal pin from the leaf bag (right side of the above photo) is seated well at the black groove of the switch. One of the black wires got broken from the switch in the above photo. The other ends of both of the wires connect to the chassis:
Now my question is, is there anyway to bypass the bag kill switch? It seems both of the black wire lead to the same metal block of the chassis so there has to be something mysterious going on on how that switch works.
I checked the two screw holes that are used to attach the bag plastic kill switch (the black thing with the groove) to the mower but it doesn't seem easy to disassemble that part for me to reattach the black wire back to it. I know it's for safety but really if the engine starts when there is no bag in the back, the worse thing that could happen will be I am covered in leave debris.
This machine doesn't have the clamp handle safety bar as the kill switch. All it has is the bag kill switch and the dead-man switch with speed settings (turtle - slow, rabbit - fast,shown on the right side of the last photo).
NOTE: Just found something that might explain the kill switch my mower uses:
it doesn't seem it can be bypass easily though. The way it works has something to do with when the safety metal pin (from the bag) leaves the plastic switch, there is a surge of some sort that disrupt the charging coil function and causes no spark from the plugs. That's why sometimes when I put the bag back to the seat the engine would keep running (when both black kill wires still attached to the switch).
The problem was solved. The spark plug from last year was covered with black gunk and didn't fire. After it's replaced and oil changed as well as some carburetor cleaning the thing works.
There is still some problem with the wiring. When I put the throttle to stop postion, the engine doesn't stop. It runs at idle speed. I did find the kill wire (green) but don't know where it's supposed to connect to. But I can always push the wire lead against the ground (metal frame) to make it stop so it's not a problem.
The engine runs pretty well and I am glad it still has (a lot of) life left in it.
