Model Forum / Radio Controlled / Land Models / March 2007NItro fuel
I just brought a gallon of nitro fuels. I went to put it in, but what was in the tank was thick. The fuel is very much the opposite. Do I suppose to be mixing a oil additive with it? Or is different percentage mixes thicker and thinner? > I just brought a gallon of nitro fuels. I went to put it in, but what was in > the tank was thick. The fuel is very much the opposite.

Fuel left a long time (I'm talking about 5 months or more) will noticably get thick and sticky as the methanol in it evaporates so don't even try to start the car without doing what I put below: Use a dribble of the new fuel to wash the tank out after emptying whatever is in it, remove the fuel and pressure lines and blow them through to remove anythign in them. Re-connect everything and then fill the tank with new fuel and go play after priming the fuel system. You may also have to open the carb (move the throttle servo by hand to do this) and then blow down the fuel feed hose to make sure that the needle is clear of any blockage.

That's probably what should be done - but what i'd probably do, due to being lazy, is just pour a little fresh fuel straight into the carb, cycle that through, then a little more and cycle that. Like with a new engine, which are apparantly often lightly coated with some crap inside to stop them seizing or corroding in transit.

That would be a better option for Simon rather than what "Doc" said as he appears to be a bit 'green', probably not a good idea for somebody with their first nitro car to go pulling the engine apart for a clean before trying to start it. It may start now but what are the chances of it starting after? Simon - do what Dan says but leave the plug out of the engine as you turn it over to avoid hydraulic locking the piston and possibly damaging the conrod.

Thanks for help. p.s hydraulic locking - is this the same as pressing the primer pump too many times and finding the pull start is harder to pull after? >> > > In that situation I'd yank the motor as well and open it up.

Another newbie here. I had trouble keeping a nitro engine running after had stood idle for 3-4 months advice seen on this post was followed with fresh fuel and new inline filter engine fired up on 3rd pull and now running well.
