So, first off I purchased the Stage 2 go kart upgrade kit for my Predator 212 that is for my Carter 2 seater go kart. Once I put on all of the items I fired up the engine (still off of the kart) and it ran just fine except the governor kept it from really opening up. So, I decided to go all in (well almost). I then purchased a billet flywheel, billet rod, new piston with new rings, mod2 dyno cam, and 4 post spark plug. I get all of these items installed and put the engine all back together and fill it up with Mobil 1 Synthetic oil. Since th I used assembly lube on the internals as I put it all back together and torqued everything to the suggested settings. Now the darn thing won't start. I've set the valve lash on the intake and the exhaust to the specs of the cam which is .003" for both. I've also set the coil gap to .030" as it stated on the flywheel. I also read that using synthetic oil as a break in oil is not a good idea. Could that really be preventing my motor from starting? I've even tried putting gas into the spark plug hole and it still doesn't fire up at all. I've noticed a little white smoke coming out of the air filter while I'm attempting to start it and I'm really just not sure what to do next. This coming weekend I am going to drain my synthetic oil and open it back up and make sure all is well with the internals. What suggestions/comments/concerns would you all be able to assist me with in regards to this situation??? After all this time, effort and money spent I would really like to hear this thing purr (or hopefully growl). Thanks in advance for your assistance.
