trying to start himOto buggy
I am trying to do the break in I get it started pretty easy but when I take the glow plug out it cuts off. And how do I stop it from pre rolling sorry if I sound crazy but this is my first nitro and I just want to get it going thanks

RE: trying to start himOto buggy
New engines can be a pita to get through break-in sometimes.
If the engine is dieing when the glow plug ignitor is removed then you are probably too rich on the HSN. But, you want to be rich during break-in so don't back it off very much. Only enough to keep it running. As a matter of fact, it won't hurt for the engine to run with the ignitor attached while it idles and warms up. Don't worry too much about the moveing forward at this point. That's a function of not being tuned yet and you'll fine tune it after the break-in. If it's just trying to really go right now then you can back out the idle screw a little. Before adjusting the idle be sure that the throttle trim on the radio is turned down.

RE: trying to start himOto buggy
i posted this in another thread. you dont have to replace lines but do check them and the glow plug.;
check/ replace fule lines, check tank, remove and check glow-plug, replace it as they foul very quickly after break in, there are two bogging sounds a engine will make one is a deeper almost gurgle, one is almost like it cuts out, typically the gurgle is caused by the high speed being too rich, the cut is from too lean a high speed setting or low speed being too lean.
once you replace glow-plug, glow plug igniter battery, and lines, start it up then quickly pick up the car, and revv the engine, a medium cloud of smoke should pour out, and have just a slight hesitation, followed by a very rapid and fast rev, if not, adjust the high speed, if it starts to rev quickly then bogs, with little smoke, richen it up with 1/4 turns counter clockwise, revving it up each time. if it bogs a long time with thick smoke and revs high, it is to rich, lean it by turning 1/4 turn clockwise.
