So I got my Firestorm and I had no problems getting it started and broken in. Now after about 7 tanks at factory settings I've tried to tune it. No luck at all. I dont know whats going on with it. Here is the situation:

I started with the HSN. On factory settings, if I let it go on WOT, it reaches high RPMs and then dies. This is the part I dont know how to explain. At first I thought it was sounding like it was bogging down. But now I'm beginning to wonder. The engine makes a weird noise when I reach top RPMs, then it takes a while for the RPMs to get back to idle, then once it idles, if I hit the throttle again, it makes the weird noise. I need to let it sit for a couple seconds, slowly open the throttle and then I can bring it back up to high RPMs (but then it does the same thing). Now, once I try to lean it out, it makes the weird noise even lower in the RPM range. The more I lean it out, the faster it does it. Like I said, at first I thought it was just bogging down, but I may be right or I may be wrong. I dont know what an engine bogging down sounds like. It kinda sounds like the engine has too much fuel sitting in it, so it cant burn it off properly. Anyways..

Then in the ST forum, someone mentioned that they had a similar problem and the LSN was too rich. So today I tried to lean out the LSN and all that did was add to my problems. When I lean out the LSN it does the same thing as when I lean out the HSN, but the only difference is that once the engine dies, its a pain in the rear to get it started again. Once it does, the RPMs will drop fast enough that I cant even take the glow plug igniter before it dies.

I'm just going to revert back to the factory settings and hopefully just get it started again. I tried very hard to give a good explanation of what my problem is, so hopefully someone can shed some light on my problem.

I should also mention that I just put a new glow plug in there so I dont think that is my problem.

Bring it back to factory settings and start from the LSN, also put your idle up by half a turn clockwise. The idle limits how much the carb closes and it might be too small and might cause a stall when u let go off the throttle (it happens alot). Your idle should always be consistent, it should always make the same rpm noises, if it changes noise after u do a WOT run to idling your LSN is too rich.

Always do WOT runs after each setting change to clear the crank of the old fuel and let the new settings kick in. Heres a quick tuning flow chart:

Also try running it with the glow plug ignighter left on the plug and if it runs good then you need a new plug maybe a little bit hoter??? Give it a tray and also use the flow chart.
