rich, looks nearer 11 not 12 on that photo!...Good one Rich anyways. Looking forward to seeing data from a few more people. Am already sold on the benefits of this system. Regardless of how near to 12* the 'sweet spot' is, looks like a great static timing tool, (I hate the dial indicator method). But think ill be making something using lift sensor and crank position sensor and an arduino instead of buying pulse adapter gizmo.
I don't want to get ahead of myself but when I'm through checking mine I'd like to lend this to other interested parties who are on a similar quest.
...BTW your Bieber avatar is awesome.-Malone
On Rabbits isn't the square block of metal near the timing mark 12?
VanBcGuy, Is this the MT 257 model? I have use of rbremillers MAC for a bit and I just picked up on an older Snap-On MT254 Lumy adapter. My trouble is the special tube that goes into the glowplug spot is meant for the Izuzu Pup engine. They have really long GP's and so trying this adapter in the glow plug hole in a head that is off the engine I saw it was about 3/4 of an inch too long. So I was all over town looking for a fitting that would go into the head and allow me to insert the adapter into it instead and take up that 3/4 of an inch. No one sells metric threads in this town. Very few at one place that allow folks to use standard 1/8 inch American brass on Honda or VW or Toyo. engines for an oil gauge setup but that is it.Going to look at Grangier tonight in hopes they have one. I will be near one of their places tomorrow and can pick it up when out of town. The Tiny tach 6 mm pick up works on the MAC so that might be your only means of getting the unit functional. The seller did give you some of the price back so it won't cost all that much more to make it work. What good is it if it won't work?
