In the thread "Oil Test Summary by rc bugman"
http://www.rcuniverse.com/forum/m_26..._4/key_/tm.htm

captinjohn mentions (post 81) that an oil manufactor recommeds shutting the engine down using choke. captinjohn took the step further and went to shut down on full throttle using the choke.

The procedure causes the engine to suck in a lot of fuel and oil. captinjohn describes easier starting even after storage, as he belives that the fuel/oil sucked in soaks the engine and loosening up deposits, that would otherwise settle.

No one really commented on this statements, what do you think?



As I sidenote, the manual for MVVS45 specifically says not to run the engine with the choke on:

"Caution!!! Never close the choke valve completely when the engine is operating! The choke valve is set to allow minimum air flow only when fully closed, which could cause damage to the intake reed valve."
