Anybody have similar problems?
Got any suggestions?
Thanks!
BTW: The TZ is really tight at TDC, even after going through two tanks of fuel.
It takes much more than 2 tanks to break in a motor. 10 tanks is more like it.
Your engine setting is too rich. This is fine as it is set for break in. But you should gradually lean it after say 5-6 tanks.
If you need to know how to break in your engine here is a good article you can read:
