Hey guys I recently purchased a used l3200 with 128 hrs on it, was told a old man had it and used very little. I started by brush hogging with it and noticed after 30 to 45 mins it would just start to bog down and started smoking, with a little persuasion with my foot throttle it smoked a bit more and cleared out and back to work I went. Well the problem persisted til now and it seems to be more and more now. Just splitting wood stacking it in the bucket and using foot throttle I’d I get up to pto Rpms it’s started to spit sputter and smoke more heavily now then before. I have changed air filter (2) fuel filters and some k100 also some injector cleaner. Problem is still there. I have roughly 140 hrs on it now and this problem is such a nuisance. The kicker is that it starts fine and runs perfect at low RpM. But once I use the throttle to work it Pto or pick up speed the problems start again. Never stalls just loses all power smokes when idled up and runs choppy while on throttle. If I let off throttle and just normal driving it fine, but once under load by pto or throttle it starts again. I haven’t cleaned the tank yet, and I’m not ruling out a dirty tank with bad fuel when I purchased it. Any and all help is greatly appreciated!

Another vote to dump the fuel.
Remove the rubber hose from the fuel filter (assuming yours is rubber and it is a convenient location) and let the fuel run into a clean light colored container. Watch for good consistent fuel flow and note what the fuel looks like in the container.
It's very likely the fuel is contaminated with bacteria from sitting so long.
After refilling with fresh fuel use a biocide to make certain anything left inside the tank is killed.
For preventative measures, I personally use a biocide when refueling.

Ok guys tank is cleaned new fuel and biocide added. Any tricks to firing her back up I believe I have some air in the system
The owner's manual should have instructions for where and how to bleed air from the system. If you don't bleed the air it probably won't start.
Well I know it’s to soon to tell but all is right so far and runs strong, no smoking or power loss. Bleeding was a pain in the ass but we got it. After draining the fuel I saw quite a bit of sediment and Black flakes. Is it recommend to keep the biocide to it? I also added some power service injector cleaner and fuel and tank cleaner. Thanks for all the help! You guys are the best!
Yes.
There is usually two different dosing options printed in the directions. Lesser amount for maintenance and more for when there is a problem. I'd probably use the higher dose for at least one tank and then go to a maintenance dosing.
