power accusation went lean several reasons motor could slow down possibly quit properly broken-in model motor running right fuel plug properly cooled does sag heat up fuel level dropped too far needle tweaked too fan What should happen motor just slows very slightly quits firing cases motor sags down cooks three probable causes crankshaft bearings getting enough cooling fuel heat up start dragging 2 cylinder piston dont have enough clearance start binding 3 usual cause motor starts pre-igniting motor leaned makes power also makes heat makes heat plug element gets hotter ignition starts occurring soonen motor has little extra heat added because being new creating friction because weather hot because thefuel has too much nitro because glow plug retains too much heat motor can come up critical point ignition starts too soon over-advanced ignition combustion pressure presses piston down part up stroke turn generates morefriction heat again further aggravates pre-ignition problem Most model motors set up will run very close pre-ignition point because way get power Once motor goes over power peak way get back throttle back cool off Remember start lean motor get maximum power motor warms up seems slow down suffering pre-ignition slight bit pre-ignition dead lean setting may too bad because way usually get power out motor However much sagging dead lean setting giving away too much rich lean tolerance motor something should done Switching cooler running plug helps Reducing nitro fuel can make lot difference Adding little oil fuel can help some put together reasonable quantities isnt enough reducing compression ratio orden Unfortunately see lot cases pre ignition days reasons nitro expensive afrw years back people thinking nitro means power will order expensive

power accusation went lean several reasons motor could slow down possibly quit properly broken-in model motor running right fuel plug properly cooled does sag heat up fuel level dropped too far needle tweaked too fan What should happen motor just slows very slightly quits firing cases motor sags down cooks three probable causes crankshaft bearings getting enough cooling fuel heat up start dragging 2 cylinder piston dont have enough clearance start binding 3 usual cause motor starts pre-igniting motor leaned makes power also makes heat makes heat plug element gets hotter ignition starts occurring soonen motor has little extra heat added because being new creating friction because weather hot because thefuel has too much nitro because glow plug retains too much heat motor can come up critical point ignition starts too soon over-advanced ignition combustion pressure presses piston down part up stroke turn generates morefriction heat again further aggravates pre-ignition problem Most model motors set up will run very close pre-ignition point because way get power Once motor goes over power peak way get back throttle back cool off Remember start lean motor get maximum power motor warms up seems slow down suffering pre-ignition slight bit pre-ignition dead lean setting may too bad because way usually get power out motor However much sagging dead lean setting giving away too much rich lean tolerance motor something should done Switching cooler running plug helps Reducing nitro fuel can make lot difference Adding little oil fuel can help some put together reasonable quantities isnt enough reducing compression ratio orden Unfortunately see lot cases pre ignition days reasons nitro expensive afrw years back people thinking nitro means power will order expensive

power accusation went lean several reasons motor could slow down possibly quit properly broken-in model motor running right fuel plug properly cooled does sag heat up fuel level dropped too far needle tweaked too fan What should happen motor just slows very slightly quits firing cases motor sags down cooks three probable causes crankshaft bearings getting enough cooling fuel heat up start dragging 2 cylinder piston dont have enough clearance start binding 3 usual cause motor starts pre-igniting motor leaned makes power also makes heat makes heat plug element gets hotter ignition starts occurring soonen motor has little extra heat added because being new creating friction because weather hot because thefuel has too much nitro because glow plug retains too much heat motor can come up critical point ignition starts too soon over-advanced ignition combustion pressure presses piston down part up stroke turn generates morefriction heat again further aggravates pre-ignition problem Most model motors set up will run very close pre-ignition point because way get power Once motor goes over power peak way get back throttle back cool off Remember start lean motor get maximum power motor warms up seems slow down suffering pre-ignition slight bit pre-ignition dead lean setting may too bad because way usually get power out motor However much sagging dead lean setting giving away too much rich lean tolerance motor something should done Switching cooler running plug helps Reducing nitro fuel can make lot difference Adding little oil fuel can help some put together reasonable quantities isnt enough reducing compression ratio orden Unfortunately see lot cases pre ignition days reasons nitro expensive afrw years back people thinking nitro means power will order expensive

power accusation went lean several reasons motor could slow down possibly quit properly broken-in model motor running right fuel plug properly cooled does sag heat up fuel level dropped too far needle tweaked too fan What should happen motor just slows very slightly quits firing cases motor sags down cooks three probable causes crankshaft bearings getting enough cooling fuel heat up start dragging 2 cylinder piston dont have enough clearance start binding 3 usual cause motor starts pre-igniting motor leaned makes power also makes heat makes heat plug element gets hotter ignition starts occurring soonen motor has little extra heat added because being new creating friction because weather hot because thefuel has too much nitro because glow plug retains too much heat motor can come up critical point ignition starts too soon over-advanced ignition combustion pressure presses piston down part up stroke turn generates morefriction heat again further aggravates pre-ignition problem Most model motors set up will run very close pre-ignition point because way get power Once motor goes over power peak way get back throttle back cool off Remember start lean motor get maximum power motor warms up seems slow down suffering pre-ignition slight bit pre-ignition dead lean setting may too bad because way usually get power out motor However much sagging dead lean setting giving away too much rich lean tolerance motor something should done Switching cooler running plug helps Reducing nitro fuel can make lot difference Adding little oil fuel can help some put together reasonable
