MrJ451 0 #1 Posted yesterday at 12:53 AM Hi everyone - new member here, and very grateful that I found this forum! I found this Derby Tiller Power Hoe in my father's garage, but when I asked him about it, he didn't even remember having it (he's 84.) Obviously hasn't been used in several decades, and was probably only used a few times. The man has saved every manual, from every piece of equipment he's ever owned whether he still has it or not (ask me about the last 3 lawn mowers he had. Doesn't own one now, but he's still got the manuals for the others.) But this one is no where to be found! I've read through the O&R and AEP manuals in the pinned thread and found some similarities of course, but it's the differences that I need the experts help with. I've removed the air filter - foam was intact (until I removed it.) I have new foam to replace it. The sparkplug has been changed. The cord pulls and retracts smoothly, without catching/sticking. The red button on the carb springs back without issue, but it won't prime - the fuel lines are cracked. (I had a fuel leak into the bucket.) It was stored with fuel in the tank as evidenced by the smell when I opened it. I have not removed the cap that is attached to the fuel line. I would have, but it's stuck and I didn't want to break anything...else. There doesn't seem to be a fuel vent like on many of the other motors. UNLESS that's what the tiny cylinder is that's attached to the fuel line, right before the carb. Obviously I want to replace the fuel lines, but I haven't been able to find dimensions to go with the part numbers (38-11?) The line going from one side of the tank to the other is the one with the leak that I've found. And I have no idea what that little cylinder is - or where to get a replacement if necessary. The numbers stamped on the metal plate of the cylinder cover (2nd to last pic) are 13 - B - 400, 8070907 And there's no On-Off switch, so is that tab circled in yellow in the last pic my Kill-Switch? (Spark Plug Short-out Spring) Any help is greatly appreciated and I can take more photos if necessary! Thank you! Share this post Link to post Share on other sites
Wallfish 719 #2 Posted 17 hours ago That thing looks to be a great condition. The diaphragm in the carb will need to be changed. When they get stiff it won't prime or pump fuel. And clean the carb. You can follow the pinned carb tutorial. Shoot me a PM for a diaphragm. Check for spark. If no spark you will need to remove the flywheel then the points cover to clean the contacts on the points. Obviously clean the tank too Yes that's the engine shut down Share this post Link to post Share on other sites
MrJ451 0 #3 Posted 16 hours ago Yeah, aside from a little oil spillage on the tank and exhaust, and some dust, that's how I found it. I'm in my mid-fifties, and I've never seen my father use it. I was afraid someone was going to say that about the diaphragm. Will send PM. Any idea about the inner dimensions on the fuel lines - or at least the one leading to the carb? The other one seems to be about 1/4" and I've got enough spare tubing around here that I can do some trial & error, but I don't have anything as small as that one line. I've seen 2mm/.08" ID tubing on Amazon - does that sound right? Thanks so much! - Joshua Share this post Link to post Share on other sites
