The Static tube falls in the same class of things as a V-stack.,,,, Black Magic

RE: Elect. ignition for Poulan 25cc?
Ya'll have me worried now. Here I was grooving along and thought I had it all figured out. Now a new problem I have never heard of before. I definitly do not want to tempt the black magic gods. Murphy just loves to bug me. [:@]
So what I need to do is remove the cover from the carb and solder a 1/8 " brass tube in the hole and run it toward the rear? Will ordinary wire solder work here since it should be heat insulated from the engine by the intake manifold? How easy is it to solder to the cover? Questions Questions Questions.

You can sure try it and see, but personally, I like to avoid all possible problems/frustrations. Especially those that could be tough to fix once at the flying field, thereby ruining an outing.
I put a little tube in any of mine that face into the slipstream. Weird things can happen with the airflow. A friend of mine had a Homelite that ran perfectly when upright, but would go rich when inverted. He was afraid to fly inverted because he thought the engine might quit. (His was an uncowled airplane.) We put a little tube in that regulator cover, turned away from the slipstream air, and it worked perfectly from then on. He said he felt like he had a new airplane!
Your choice; these are just my experiences and observations....
If you look close in this pic of the twin I made, you can see the little 90 degree tube I installed on that carb.

I see the on-board glow...do you leave it on all the time the engine is runing or just for starting? Capt,n

RE: Elect. ignition for Poulan 25cc?
I noticed last night that the setup I have to hold the sensor in place is not working out too good. The sensor I used has the output wire coming out of the top. I ran the clamp over the top of the wire to hold the sensor. Now the clamp has rubbed the insulation off the wire and is shorting out the sensor. I put electrical tape over it but not a good solution. I need to find some way to mount the sensor to the clamp from the outside. I have thought of using epoxy to mount it. I can always adjust the timing just by moving the clamp. But was wondering if you guys thought the epoxy would be strong enough to hold the sensor to the clamp. Or if you guys have another idea.
Thanks
Jim

The way they come from CH Ignitions works pretty well. They solder a small brass channel to the clamp, and the sensor fits into the brass channel. One drop of thick CA glue will hold it into the channel just fine. You can get the brass channel from the K & S rack at the hobby store.

Sounds like a great idea but alas no hobby stores closer than 100 miles of me. Had another thought. What if I wrap the ears of the sensor to the clamp with some thin tie wire and then spread epoxy on it. Or just thought of using a thin plastic tie strap. What do ya think?

Well as it turned out, wrapping anything around the sensor moved it too far away from the magnet to work. So I just tried using 30 minute epoxy to glue it to the clamp. Seemed to work great. Cant pull it off if I tried. Looks much neater too. Good spark as well. Time will tell how it holds up in the air though.
