After a complete teardown last night i now know that it is no CRF enginge, but infact a Discovery 3 port ORI80657
And as that engine is intended for people new to the hobby, i wonder if that can be the reason why it did not last more than 1 gallon as a race engine, anyone here know if this could be the case or if the engine even if used for racing should last longer.
