My son's Nitro Hawk is having an odd fuel problem.
The thing ran rich from day 1 (bought it used). I didn't want to mess with it cause the thing worked. When it didn't want to stay running, I had to step in and mess with it. There was fuel all over the hsn. The fuel lines were worn badly so I replaced them.
I started it up and it spat fuel out the exhaust pipe (then the fuel would load up and kill it). I tried to lean it out. Leaner and leaner the same thing. It was down so lean it didn't want to start or stay running at all.
I reset the hsn to 1 and 1/2 turns out. It ran but it still was rich and spat fuel out the exhaust.
Then it seemed like the glow plug died. If I took the igniter off, it would die. I changed the glow plug and that glow plug started doing the same thing. I think when too much fuel collects on the glow plug, it acts like a dead plug. I replaced the orginal plug and it seems to be ok for a little while before doing the same thing.
Now, I think I've killed the one way bearing because I can't turn the engine over, it just spins.
Anyway, before I killed it, it seemed like it was getting too much fuel no matter what I did. Is it possible for the pressure from the exhaust to push too much fuel out the tank and through the carb and overdrive the HSN?
I did also lean the lsn quite a bit too.
Has anyone had a problem with their nitro getting too much fuel (way too much) and was unable to control it with the needles?
