It is still too cold outside to do more testing........but my only option is leaning the high end a little bit more to gain milage, but then, i have to keep an eye on the temperature.
Bigger engines use more fuel, that is a common law............
75cc tank designed for 2.1cc small block 12 engines.
18TZ is close to 3.0cc..........that explain the 4 minutes run time.
You can get more time out of this engine, I run my .18TZ at around 240-260 deg. Your trigger finger is alittler heavy to, you really have to finess this engine around the track, you will get faster when you get used to the power. Also what plug your running? Also gearing will affect your run time.
