Go to pre-mix !
You have to leave the pump as it is your Tach drive
Disconnect the oil feed line and plug / cap the inlet stub - car wheel cylinder bleed screw rubber caps work great
Disconnect the oil lines from the pump to the inlet stubs
Cut a lenght of injection line and connect the inlet stubs together
Cut another piece and connect the injection outlets together on the pump
Remove the cable and bin it , plug the hole
There's enough oil in the pump to keep it alive if you keep the water out - my missis' sled has been running this way for the last 5 years
With good quality oil 40 to 1 works just fine
Go up 2 sizes in main jet or you will be too lean
