The timing remains the same. The RCEXL ignition retards the ignition internally under a certain RPM. It comes with it's own Halls pick up but I see no reason why you could not use the CRCC pick up. I did not but the wiring is the same ( I think ) and yes I had to alter the brackett also in order to get the timing advanced enough. It was even more difficult than it was with the stock brackett, I almost ruined the brackett I read on here where someone had to make a new brackett in order to make it all work right.

As I said before when properly set up this is a good working engine but I wish it came set up that way from the factory. On the other hand I bought a very popular 50cc engine, paid 4 times for it that I paid for the CRCC engine and it took 3 trips back to the manufacturer to make it work right - go figure !!!


[X(] I just reread your post and to REALLY answer your question YES the engine ( with the STOCK ignition ) and timed @ 30 degrees was a BIT harder to start and idle which is why I installed the RCEXL. BUT the engine worked so much better at high throttle that I feel it was worth keeping it advanced and installed the RCEXL;. As I said it was all worth it to me but others may not feel the same way. In that case go with your gut
