Default Kero Start Rhino unreliable starts

Have a kero start rhino with 5 hours on it that the starts are not reliable. Sometimes it starts fine sometimes once the burner is hot and rpms come up and it starts to inject kero I just get white smoke out of it. Try again and it my start. I turned the glow plug voltage up to 6 volts which helped and the pump start is 31. Seems like either the glow plug is not hot enough to fully ignite the kero or too much is being dumped in. Once it does start it runs perfect. I'm using a 2S 4000mah LIPO.

Can it use a 3S LiFe or A123?

It's accepts 2S LIPO or 3S LiFe. Using 2S LIPO.

3S LiFe may be the answer to the problem.

It started fine for 5 hours and 35 starts on the LIPO.

Sounds like either the burner or the battery is getting weak.

Do you know what the stock voltage setting and pump start settings are? Replacing the battery is easy enough but it doesn't seem to matter whether battery is fully charged or 80% dicharged when it happens. Just want to make sure it's not an incorrect start setting.

Thanks for your help. I'm sure it's something simple.

If this is case, and you didn't change a setting, it can't be that. Try a new battery first, it sounds like the battery may not be delivering the correct power anymore; and it's easy enough to try/check.

I suggest to try first to lower the "Pump Power Ig K" value, too much fuel can cool down the igniter
You can check in the second screen how much the voltage drops during start up, if it is too much (more than 1-1.5 volts) maybe battery related
Hope this helps

Thanks for responding Juan. I don't remember the voltage dropping a lot and the pack charge level does not seem to matter but will check that first. Was thinking that as the pump loosened up it might be dumping in too much so I will decrease it some if battery is OK. Also if the burner lights and the start progresses to fuel ramp is it normal to get 8 inch flames, not a lot and just for a second but none of my other turbines do this. Seems I read somewhere that the Rhinos do this but may be wrong. Thanks Again.

Hello yellowbird911
Reducing the Pump Power Ig K will also reduce the flames, as you say, the pump might be a little more loose and dumping more fuel
The goal is to have as little fuel as possible during the startup

Hello,

i would change the battery to a 3s Life battery. Kero Starts turbines prefer a 3s life over the 2s lipo. Like Juan said also lower you pump pw k to around 26 and lower the glow to about 5.8.

Please call all me at 321-412-3078

Also check your filter, if the volts during start are within the normal range I would check the filter just to eliminate all the possibles.

Turned down pump start to 26 and glow to 5.8, no luck. LIPO was only dropping 0.6 volts but changed to a123 3S which had voltage drop of .8 volts, still no start. Turned glow up to 6.3 and bingo. Is 6.3 volt too much? Turning down the pump did eliminate the small amount of flame at fuel ramp. The in line filter is clean, is there one under the inlet cover also. It starts and runs perfect with a little higher glow voltage. I do have an eighteen inch extension harness sold by Xicoy for the starter and glow plug. Just a guess but maybe there is a voltage drop though the extension so a higher voltage is required? Thanks for your help. Did try to call but it was probably too late.

Hello yellow
Just keep the lowest glow setting possible that gives you reliable starts
Regards
