Upshur's opposed twin engine

[Jasonb]

A couple of twists of wire would do the job and look less cumbersome or bend your own from spring wire.

I thought I recalled Brian saying there was a hobby shop nearby. They should have tiny hose clamps, they use them a lot for Radio control stuff.

I don't like gear clamps!! On something big like a car radiator hose they are fine. On something as small as a model engine, not so much. I had hoped to get a smaller version of the spring clamp laying in the foreground, but couldn't find any in Barrie. I have just put the smallest gear clamps I could buy in town on the intake manifold tubes. Kind of ugly, but they will do for now.

Amazon has about 5 lifetime supply for $10 of the flat spring clamps typical of fuel lines

There's also these, only one lifetime supply for $10 but they look more like what you want

Sparky, I already told him to try an RC shop as that is where I have got them.

I've been to the hobby shop in Barrie. They do not carry what I want in sizes large enough to go over a 3/8" o.d. gas line. The second ones that L98fiero suggests are probably as close as I am going to get to what I want.--Now that I have the gear clamps I will probably keep them, but I will definitely try the ones L98fiero suggests for the next engine I build. I tried to start the engine today, but there were sparks arcing across from my distributor center terminal to the outer terminals. I will build a new insulator (The yellow piece) and install it to try and prevent arcing.
