I checked the valve clearance. I have not pulled the head yet. Praying the injector fixes the problem. New injector expected to arrive tomorrow. Stay tuned…. Thanks. Merry Christmas! Sent from my iPhone using Tapatalk

I will definitely check this once my new injector arrives. Should be here on the 26th. Thanks!!! Sent from my iPhone using Tapatalk

It’s hard to say. I do not think it has been messed with but it’s hard to tell. Sent from my iPhone using Tapatalk

I pulled the exhaust cover off and looked as far as I could into the muffler. I do not see any signs of a spark arrestor. My new injector should be here in a few days. I managed to break the tip off the injector at some point during my tests. I’m hoping it was just a leaking injector. Will...

I will double check the inlet to the injector pump. I have not bled the high pressure line to the injector. I will do both of those. The governor is hooked up to the injection pump properly I did check that. Thanks!! Sent from my iPhone using Tapatalk

Oh that’s a good one too. I took the fuel line that feeds the injection pump and put it in a glass. Ran the fuel pump and watched the flow. The fuel coming out of the line was solid and I saw no air bubbles. I assume that was the only way to check for air bubbles? Thanks!! Sent from my iPhone...

So I did as you described. Spray pattern looks good to my untrained eye. It was really hard to tell if it was leaking in between sprays but if I was a betting man I would say it dropped a little in between. Think I will go ahead and order an injector. I will update as soon as it gets here. If...

Thanks for the reply. I was thinking the same thing about the injector being stuck open. Unfortunately I do not have the tools to test for that. I did not want to start throwing parts at this machine but I might just have to pick up a new injector. I will have to check the timing too. Thanks!!

Hi All, This is my first post. My new to me MEP 831A has me stumped. It starts quick even in the cold. But it billows tons of black smoke, the governor arm has to stay WOT just to keep it running. After 2 min or so the muffler glows orange and backfires really loud with flames out the exhaust...
