eNVy Racing wrote:This is a replacement underhead button for the Team Orion Wasp .28 and Peak Diablo .28 engines. These engines use turbo glow plugs with the stock factory head. This button converts the engine to use a standard glow plug and offers better all around performance of the engine.
This underhead button also cures the problem with these engines leaning out after coming off the throttle. This problem has been experienced by many using either of these two engines. Standard glow plugs also save you money! Standard plugs average around $4-$5 each while turbo glow plugs average around $7-$8 each.
eNVy Racing recommends the use of a long plug, such as the McCoy MC-8, although short plugs, such as the O.S. A5 also work well. eNVy Racing supplies recommended beginning needle settings as follows:
LSN: 3 1/2 turns out
MRN: 1/4 turn out
HSN: 4 turns out
These settings should be used for engines which have already been broken in. When breaking in an engine with this button, it is recommended to go 4 turns out on the low speed needle, all the way in for the mid range needle and 4 1/2 turns out on the high speed needle.
