Eyedropper style fuel tank for TD .010

Yeah, that's what I thought. Tried it and I don't think the fuel is being drawn into the engine. The engine turns over with a prime but does not run through fuel that is in the eyedropper and the fuel line. I cleaned up the engine so all of the openings are clear. The examples that you sent are non-TD Cox engines so I don't know if that makes a difference.

I don't use my TD .010 too much. Keep the fuel line as short as possible. If your eyedropper has a bulb on the top, you need to drill a hole in the top. Make the hole larger than needs to be because the rubber will spring back and somewhat self seal the hole. You can use the bulb as a primer. Pull it up and then put your finger over the hole and push it back down and you should see the fuel move up the fuel line. Continue to do so until the fuel is just entering the spraybar nipple and then prime and proceed to start. If the eyedropper is too low, this can also cause issues in getting the fuel to the engine and if too high, the fuel will self siphon into the spraybar faster then you can get it running.

Appreciate the information Ken. I'll give it a try.
I just realized that I posted this in the "non Cox engine " section. I will have continue it in the Cox section.

Hello- just following up on the eyedropper topic that I brought up.  I ended up using a modified 5ml syringe as the basis for the 010 fuel tank instead of an eyedropper.  The good news is that it works very well.  Thanks to all of the input and information that I gathered from this and other sites I was able to come up with a compact, lightweight design.  I am using it on an 010 version of a 1962 free flight design called "Fluff".  Not sure how to add photos to this topic.

Nice to see it completed, looks functional.

Looks Good , was this a kit ? Like the way you got the syringe wedged between balsa? Is that fuel proofed too Looks bare.

Sorry for the delayed response. The 010 "fluff" was not a kit. I had the plans. 1/2A/A full size Fluff design was published in Model airplane news back in 1962. It was also scaled for 020 and 010. I know because my father, Tony Faranda, was the designer.
Yes I did fuel proof the balsa syringe tank holder area. But I left it bare wood rather than covering it with tissue.
