Here's the photo @Wallfish Spark works fine. When I started cleaning the tank, paint flaked off, so I'm removing the rest and it'll get a new pain job. Found replacement fuel lines, and I'm adding a fuel filter for good measure. I'm leaving that small cylinder before the carburetor attached since I'm not sure what it is. I'll post pics when I'm finished.

I've seen 3/32" tubing also, so that will give me plenty of options. Thanks again @Wallfish!

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

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!
