i have odonell racing fuel its 8% oil 20% nitro. i also have some traxxas 20% but im not sure the oil mix. my LHS doesnt have any other odonell fuel blends and all the sell is gallons so im stuck with what i got. can i mix the traxxas with the other since i noticed that the traxxas top fuel is a litle bit "smokier". also what oil can i add are you referring to castor oil??,
should i get this castor oil; before i go any further i really cant afford to burn the engine up, i have already done 3 tanks.
another problem im having is after preheating the engine the fuel is moving away from the carb making it really hard to prime. i tried manually priming but that is flooding as i really cant see because i dont have that much extra hose. i am puttin a piece on the fuel tank on the nipple for the exhaust line. will compressed air from a can help if i just blow it on the carb to try and cool it off.
i have a hard time preheating all i have is a hair drier, and i can just barely get the engine to 200 deg.
