Hey thanks! So these numbers are opening right? So I would look for the port to just barely open and then that is the timing right? Where do I get the bearings and is there any machining involved? Thanks!!!
I am anxious to try this!
I actually considered building my own expansion chamber, and build it with two cones and a straight section in the belly, any idea where would I find the math to figure out the profile? I was just going to try and copy an existing design to get close and then play with it till I got it right, but if you know a good starting point for these little motors I would greatly appreciate it!!
