Fewski,


If you break your ABC/ABN car engines [link=http://www.rcuniverse.com/forum/m_1850473/tm.htm]this way[/link], they will last a lot longer.

If you do an extra rich break-in, as the engine manufacturer and seller want you to do[>:][:'(], it will hold up for 2-3 gallons...
Parts cost more than engines...
