Would this be considered out of spec for timing, though?

Thanks!
I did spin the car during an autocross -- I posted an image of the timing in the post above, maybe you can be my second opinion to determine if that's enough to be considered "off timing".

The TCT that was on the car was a Billman TCT "BMX". I do have a spare, TCT which is also... a Billman "B X" TCT. I don't know if there's any difference between the TCT's.

Does the S2000 have the capacity to read RPM from the cam sensors or only the crank position sensor? Because on attempted start up, there is some RPM's on the dash. I've ordered a crank position sensor as I'm running out of ideas.

It might help to show all the timing marks.

From that angle, it looks okay. Maybe, try for a straight-on look when you get a chance.

Off a tooth is not something you have to wonder at. It'd be way off.

A little chain 'stretch' if what you're dealing with when it seems slightly off.

Obviously, metal of the chain isn't actually stretching, its just incremental minute wear at each link that adds up to something measurable in overall chain length. So it appears to have stretched, like a belt would.

A small amount of stretch isn't something to freak out about. Not like you must replace chain.

Any resolution to this one yet? Also curious if you did "2-in" when you spun out?

Yep, always 2-in.

But, no concrete resolution yet... I'm about to try the Fuel Pressure Test; Fuel Pressure Relieving from the S2000 manual. I recent tried to replicate the fuel problem and I couldn't replicate it -- dry spark plugs, no fuel. I wonder if when I had done the test before I still had fuel in the system making me falsely think that I had fuel. Though it wouldnt explain why I can't get spark.

Gonna double check for continuity and resistance on the Crank Position Sensor then...

I'm probably a day away from sending it off to Honda and letting a real mechanic figure it out.
