I have an eMax 22 gear and get the same white smoke on startup, but only about half the amount based on your video, and mine usually cranks the first time. I use Howes diesel treatment in mine. I would run a can of Seafoam through it before I went to the trouble of tearing it down. Seafoam has worked well for me on other equipment.

Thanks for all the advice/info. I have put about 150hours since purchase, and run the mahindra cleaner/fuel additive for most of those hours. I just tried a full throttle start, and that made it quicker to start but no less smoke. I also have the high rpm issue to work with as well. I have decided to pull the injectors and have them cleaned/serviced, and while i was disassembling i noted a little rust and jelly looking substance when pulling fuel lines so im suspecting my injectors may be fouled. A local shop seems very helpful and said i should be able to get them tested and serviced for under $500 so im gonna try that first. He also added that i can do that first and then if that doesnt fix it, we can look at pump which is roughly $1000 to rebuild. So im hoping the pump is ok and the injector service will fix this issue.

So i just got a call from the shop that has my injectors. He said he had them on the tester and found that the flow was sporadic and the spray patterns were all over the place. He also said that when he disassembled them to get the numbers etc, that they appeared to have been disassembled before and werent put back together quite right. He suggested that this is very likely the cause of my problems and quoted me $65/each to rebuild and $40 for the diag time. He said i should have them back within a weeks time and hopefully i have a tractor that will run like new after this.
So, i have been letting the plugs run their full cycle (they time out at roughly 40-45seconds), and the dealer suggested that maybe i run them shorter as well so i did that, but it was not any easier to start. When i pulled plugs to check them they appeared clean but i took scotch brite to the plug end anyways and cleaned them up even nicer. The battery is pretty new and tests good, I checked cables and connections and grounds and even cleaned the ground connections on frame. Engine cranks just fine and all electrical appears to work fine as well. Im fairly certain the fuel system is clean up to the pump as i have not seen any more water and the filter looks clean as well. Not to say that the pump or injectors weren稚 contaminated previous to me owning it. So in my mind ive kind of narrowed it down to injectors or pump or both and was just hoping to see if anyone had any insight before i tear it down and ship stuff out for rebuild $$$$$. Im assuming you have an emax22.. How is yours to start, and does it do any popping or smoking at high rpms??
Stupid question...manual say nothing about holding the key in the glow plug position. Do you have to hold the key in the glow plug position until the glow plug dash light goes out?
Thanks,
Chris
Chris, on my emax 25 I just turn switch so the glow plug light comes on. Don’t have to hold the key. Then once the light goes out I turn key to start it!
That's what I assumed - the owners manual only mentions to turn the key to the left then start. I wait until the glow plug light goes out before starting. I did noticed when I turn the key to the left the glow plug light comes on the dash but goes off quite quick. One time, during starting, the glow plug light came back on, after it was running, and stayed on for a while. Thought that was odd...
Thanks,
Chris

there's a connector on the glow plug rail, its cheap and becomes loose... if you hold it tight against the the connector it slides on, it should start... if the connector is gone, simply cut it off and crimp on a new one... had to do it on a 26 max xl gear... take a meter and see if your getting 12 - 12.5 volts to that connector, if you are, its probably a bad/loose connector...
if you need to start the machine, simply take a heat source (I use a torpedo heater) and aim it at your oil pan for a couple minutes, you'll see the white smoke start to turn blk, it'll start shortly after...
good luck...
