can premix make the car not start it sat for a long time

[imiitek]

the car was running fine after rebuild done away with the oil injectors
and put in 20L petrol mixed with about 400ml 10/40 oil
i no its a lot but was running fine that day the next day it was running fine
come to it few days later car struggled starting then runs for 3 sec then cuts out all ignition is fine has a spark at all plugs

any idea any 1

when i flood my engine which may have happened here, i get a tow start. 3rd gear. 30 mph with ingnition on. eventually when the oil and/or excess fuel have burnt off the engine will start ok.
 
On a new engine which i over did the vaseline and 2 stroke, this was the only way to get the thing going

[imiitek]

i have taken the plugs out with the main fuse out and cranked engine and wen i thort it had cleared i left the plugs out over night  just to make sure i then tried it again next day same thing struggles to start i have to hold my foot half way down then runs for 3 sec then cuts out
i cant move the car or toeing sounds like a good idea the cars currently not movable

one other thing can backfire cause engine to blow up

Foot should be depressed fully down. Not just half way, this is why our stuggling to start.

pushing pedal all the way down when cranking over prevents fuel injection on start up. its built into the ecu settings to help deflood the car.. irrc rx8 also have this

You shouldn\'t be premixing with standard 10/40 dude. You need to use proper premix oil.
You also seem to be premixing at 50:1, which is about twice as strong as a lot of people run.

I thought the same? Plugs out / really good de-flood ie foot flat to the floor with gas & clutch around 20 times for 10 second intervals, new plugs and just tow start not key start and she\'ll burst into life after a few hundred yards :driving.  Keep it running for a good 30 mins and you\'ll be fine :Ladys-man

Yes, exactly,.... the fuel will probably have become less volatile with that amount of oil mixed in. So it won\'t fire. I think you need to try to get some fresh fuel into the system somehow to get it back nearer to neat fuel.

thanks guys im on the case im gona empty all fuel and fill with new what oil should i use and and how much
i assumed it was normal oil due to the oil injectors taking the standerd oil straight out of the sump

[StreetracerHCI]

why did you use all that oil in 20L with petrol?
usually for the premix i\'m use 100/150ml in Full tank, Drive normal, For Random Track Days use 250/300ml in full tank, For Strong drive 350/450ml in full tank, but many liters are not 20 liters with petrol.
for example now i\'m use 20ml or 20gr for 10L of petrol and 40ml or 40gr for 20L
For premix I recommend the IDEMITSU premix OIL or MOTUL 710/800 2T.
I hope you understand, my English is not good
Do not worry, everything will be fine
