Good afternoon fellow orange owners. I'm having a issue with my L3800 surging from loosing power then comes back to running normal. More noticeable at higher Rams. At first I was thinking algae was clogging my fuel line but then I noticed when it acts up its blowing diesel smoke out the exhaust. I'm thinking I have a sticking open injector. Any one have a similar issue? Any input would be appreciated. Thank you in advance.
L3800 surges. Looses power then regains power

More details might get a better reply.
How many hours on tractor?
Hours since air filter replaced - or within a year?
Fuel filter cleaned - or replaced?
Does this with every tank of fuel, or just recent?
Fuel from 5 gal can or 500 gal tank?
Tractor kept in open or sheltered?
Smoke is black in color - or white?
Using diesel biocide or additives?

^^^^^^^^^^^^^^yep - what he said !!! ^^^^^^^^^^^^^^^^^^^
answer those questions, then we can look into the crystal ball a little deeper!
It is stored in a shed. Has just started. Has 65hrs and was serviced at 50hrs, replaced airfilter and fuel filter during 50hr service. Tractor does sit alote. Started this after it had been sitting fora while. I always put diesel stabal additive when fueled. The smoke is more like a light blue and you its not heavy coming out, it smells like unburned diesel fuel. When it loses power thats when you see the smoke. I did add diesiel klean to it and run it, thought it had cleared it up but the last time i run it was doing it. No gas has been used in it.
Correct me if I'm wrong, but I think blueish smoke indicates oil burning. I am assuming with the low hours that a dealership did the service? I would double check, and keep a very close eye on the oil level. If they over serviced the oil it can do damage to the piston rings, causing oil to seep past into the combustion chamber, giving a blue smoke. I wouldn't imagine an additive would cause blue smoke, but the true experts in additives should be along to verify that. Hope I helped and best of luck finding the cause.

If it sits a lot, it probably needs some biocide treatment for algae.
Regular fuel treatments will not do a thing with algae.

I would usually agree that burning oil is blue but i do not believe its burning oil. Its not over full and its not low on oil, plus it does not smell like burning oil, smells like unburnt fuel and it irritates your eyes. I have seen this on the interstate from road tractors that are not up to par, they would have this blueish tinge smoke coming out of stacks and my eyes become irrittated from it and smells like un burned diesel fuel. Thank you for the recommendation for biocide for the alage. Was trying to locate something for that.
Your tractor has 65 hours on it? Why not ask these same questions to your dealer? Get them involved in your problem, then they are aware of when abnormalities started so if greater problems arise they are in the loop.
Its out of warranty. But I could call and talk to them, the worst they could say is nothing lol.
