Dave, I don't know if it has been posted or not, but there is a round screw on the opposite side of the motor as the TDC bolt, it is in the center, take that out, put an allen wrench in( I forgot what size) take the spark plug out, and turn the motor over until with the allen wrench untill your TDC bolt fits in the grove, then you know you are TDC.

Once you get EVERYTHING lined out, put the last known good running carb on it to start it. I sounds like you have adjusted the lectron away from optimum settings at this point trying to solve a problem that wasn't there. If you try a new carb with a bunch of other new things, it is hard to discern what is working and what isn't.
The last thing you want now is a carb that has been adjusted way too rich washing your new rings out, or way too lean and seizing the motor. So, get it running, warm it up, check everything, solve all problems, i.e. knocking noises, oiling, batteries, timing, etc... contact the lectron guy and set the carb back up where he wants it, then attempt the new carb on a known working setup.
Once you go to high performance parts, everything changes. Not the same as a stock motor rebuild. For others who may be thinking of "trying this at home" with "drop in engine kits", in retrospect, please post a lesson on what you would recommend and what to do if you were doing it again!

Okay I put the pics in my gallery page of the cams. One thing my friend pointed out is that we think we installed the cam tensioner bolt AFTER we adjusted the cams. I will try this part again. He also says he doubts I bent a valve. Let's see... will report with more info as soon as I can get it.

Okay I know this sounds like a dumb question...
I assume I need to remove the timing chain correct? Where do I exactly make the adjustment to line them up. I know I sound like a complete clueless idiot.. I just want to make sure I slap it back properly and get to enjoy the newfound power already.

Remove the Timing chain tensioner, then take the big cam bolt out of each cam. You can pop them off (one at a time) and adjust one tooth, put the cam sprocket back on the cam, put the timing chain tensioner back in, make sure you marks are where they should be, then give everything a good check over. and your ready for assembly.
IT looks like your exhaust needs to be rotated COUNTER CLOCKWISE one tooth,and your intake, needs to be rotated CLOCKWISE one tooth.
