CubCrafters Lycoming IO-360 (cc363i) erratic RPM and now running rough on R lightspeed ignition

[Neal]

Great info, I got my spark plugs directly from Cubcrafters, they were$13.36 a plug, so they are more expensive from Cubcrafters.

The problem here is you don't know where they got them from. They could have ordered from Amazon in bulk as well. Consider buying from an authorized distributor in the future just to be safe but I learned a bigger lesson of resistance testing new plugs before they go in your plane.

Yes. And in the YouTube video I watched yesterday he tipped off that Klaus (Light speed) makes the spark plug wires. We are supposed to change them every 500 hours. I'll email Klaus to see if he makes them for my plane and if so how much as I have a feeling it will be significantly cheaper than the $486 on the CubCrafters store.

I emailed Klaus to see if he makes them and the cost. I also added the parts required to make them myself to my Amazon cart, all MSD branded wire, 90 degree crimps, crimp tool, and doing it yourself would cost the same or more than just buying them pre-made. As it's not something we change often I don't see going down the DIY path but if my coil pack issue continues and my next step is replace some of the spark plug wires then it may be something I pursue to replace some, not all, of the wires, i.e. right ignition side only.

Did you get your spare coil pack from LightSpeed? Made the mistake buying the backup ignition battery from CC. Never again.

Wow!!! CubCrafters wants $91 for the PS-1221S battery?

Here is where I got mine in the past:

https://www.batteryjunction.com/powersonic-ps-1221s-f1

Around $30 from the above. My condition inspection is approaching so time to order one. Will evaluate shipping cost from each and order now.

Bought from battery junction - $39 shipped.

I saw CC's EarthX pricing, seems about $200 more than buying direct from EarthX. Shop smart!!!
