Default RTV? Maybe..

I would prefer one of the gasket maker products, unless you have the gasket on hand. Not all RTV types are oil proof.

Which one to use? Well: https://www.permatex.com/

Iím following along on this post because I am near first engine start with my SDS system. Thanks to all that have posted so far. Iím a bit unclear of the pointer and the mark part. A picture would help me a ton. Does anyone have a photo of that part of the process?

Thanks.

Mike S has a good write up. Look here: http://www.vansairforce.com/communit...38&postcount=3

It's important not to over think the pointer thing. All you have to do is establish that the engine is in the desired position for firing using the factory timing marks or other means, and step #2 is to add a pointer "anywhere convenient" on the ring gear. Wherever that pointer falls, simply mark that point. That is now your new "desired position".

Default Timing Pointer Ideas

Ralph Inkster came up with this simple way to project a pointer to use the rear flywheel timing marks.



He used a long drill bit and some duct tape to extend the case split centerline.





He put some additional marks on the flywheel as well.

Hope this idea helps out a few folks in this area.

That is similar to what I set up with piano wire from a seat hinge. Now building a stable platform to stand on while aiming the timing light, trying to avoid being macerated by the prop.

I don't think there is any need to be within 2 feet of the prop but you could also tape the timing gun in place and a video camera or phone, zoomed in with the monitor screen facing you in the cockpit.

I hope to show a couple ways to do it in the upcoming videos on the RV6 and -10.

I need to verify the config for my G3X RPM2 input that utilizes the green tach wire from the control box. How many pulses per rev does it output? I think it's two, but I need to verify.

Yes, 4 cylinder systems output a 12V tach signal, 2 pulses per crank rev.
