well now that my 1:1 truck is all set for now, im thinking about getting back into RC. i think i can time my exit from RC at about a month after the release of the savage flux. so yeah, its been a while. so i dug out my savage yesterday and started tinkering. all i need is clutch bell and pullstart parts wise, but i do need a new glow plug and some nitro.

but my questions. first, what glow plug should i use? the motor i have isnt stock, its a Peak Diablo .28 which uses a turbo plug. i remember the turbo plugs i had never got as hot as the regular plugs out of my stock motor. to me, it didnt seem hot enough to ignite anything. is there a certain type of plug i should use?

and 2, does anyone have any tips for tuning (or starting for that matter) a 3 needle motor? this motor has a hsn, lsn, idle, and whatever the other needle is. i couldnt get this thing running for the life of me. id prime it, give it a pull, it would run for a second and die. then i could pull and pull and it would just flood. take the plug out, turn it upside down and pull the pullstarter, put the plug back in, and repeat. everytime, without fail. i think 1 time i got it to run for about 5 mins, but it was so rich it burned through an entire tank in that time.pretty much half the tank was on my tailgate.

thanks in advance.

First..welcome back to the hobby. You should try and look up the motor specs online and see what the recomended glow plug is for the motor. Also if they have a stock tunning setting. That is always the best place to start for tuning. The starting issue I am not sure about...It sounds like you dont have enough compression. But that could be just one issue..Glow plug bad....Bad fuel...compression..etc...

I would start by doing some research and going back to square one with the truck.

Wierd question, but has the engine even been through the break-in process?

Different plugs (hot med or cold) are used depending on the outside temps, Nitro% you are using and what kind of head shim you are running. I would find the makers specs and run what they recommend unless you know what you are doing and looking for the MAX performance out of your engine. Using a hot plug with high% of Nitro on the stock shim would/could advance your timing possibly giving you predet. Pre-detonation or Pre-firing of the piston could occur while the piston is on it's way back up to the top of it's stroke. That happens because you are running a hot plug with high % of nitro. Pre-det is hard on the wrist pin, piston and crank shaft.

All of that^^ could change depending on what kind of pipe you are running too. LOTS OF VARIABLES involved.

Also, once a nitro engine is fired up, you really don't need much of a spark (commenting on your "hot enough" statment) Nitro mills mainly run on compression, all they need is that little glo from the plug unless of course it's too hot of a plug and too high of a nitro % and for that look above lol..

First thing I do with a nitro engine is seal it so there are no air leaks to play havoc in trying to get it started and tuned. I've been using Lucky 7 engine sealant - its a wicking type sealer and you don't have to take engine apart like with silicone rtv or the like.

Usually when normal procedures can't make an engine to run, something else is wrong and that may be an air leak.

We used to run something like this. Apparently someone decided to start manufacturing/marketing them. Kinda pricey IMO.

Not that it has anything to do with your problem, but unfortunately the piston/sleeves in those engines are notorious for being short lived. At least that was the case 5 years or so ago, doubtful that they've changed.
