    Default TB325 issue

    I wasn't suggesting on doing any modifications to the 325. I was just trying to figure out a way to cool it better, more theory if anything. Engine starts becomming erratic, or surging, I'll just continue on resetting the ECU as that appears to remove the problem.

    cruiser, am I correct in assuming this is essentially a generator/alternator powered inverter, just like the original pipepro was???
    Obviously, I'm just a hack-artist, you shouldn't be listening to anything I say .....

    Nope, same basic tech as a Ranger 305 with the chopper, so more of a hybrid. Same tech in the PP350. The PP304 is a generator powering a converted xmt304.

    I'm just concerned with the 325 with its 25 horse EFI kohler making too much heat, and no where really for it to go, let alone cool air getting to it in a hot enviroment. Like I mentioned, in the winter, they didn't give too many problems, but now, and its only May, I get calls every day.

    Like every machine, there are quirks

    Now Kohler allows you to add a hot air kit, which in my opinion bakes the oil and cam. so adding a cold air kit providing kohler okays it or has one, is zero to do with Miller warranty. If it extends the life of the engine and subsequent components, I can't see Kohler disapproving of it.

    If a motor cycle can have a radiator why don't they design a small CI welding machine engine that has one? It's getting to the point el cheapo global competition is going to ruin the world not make it better.

    Would have been better off keeping it the same size as the 302 and add some cooling system to it, if it would avoid these overheating issues which I'm almost certain had to do with my machine going down. Even the replacement shuts down every once in a while, I suspect it to be from overheating because when I let it sit with the doors open for a while it magically works until it overheats again...

    See, I thought this forum was also to report faults, and perhaps for Miller to have another look at the problems. If I had to t-shoot all the brands and report faults to respective tech supports, I'd be one the phone quite a bit. I report it here, and my other thread was terminated, as will this one likely.

    I reported it and maybe Miller or Kohler will fix it.

    Or simply I'll let it slide. I could have let the New Lincoln Ranger issue slide, And Kohler could have replace hundreds of engines, over and over again. Solved it and the fix is out there. think that the fix just appeared. Someone had to figure it out....

    run heat exchanger in the oil pan with a 12 volt electric fuel pump to push the antifreeze through the exchanger and have a 12 volt electric fan radiator.

    This stuff is so simple I don't know why I'm not the CEO of Miller....

    I missed the talk about problems with the 305's. Got a link?

    Nope, on a new 305G, you'll find that the top of the fuel cap is smooth, ie, no vents. It's another emmissions thing, same reason why there is no vent cap on a jerry can anymore.

    However if you continually wait for the first click on the fuel handle when you refill, your over filling the tank on that 305G, which quickly takes out the engine with double fueling and putting raw fuel into an open intake valve if the unit is allowed to sit.

    Soooo, we take a micro dril and drill the 4 ridged oval areas in the cap, and drill the shiny portions of the outside of the cap. Then we cut and plug the vent line (couple orf 1/4" bolts) (line sits to the right of the right side spark plug) presto you now can fill the neck right up with fuel and no danger of taking out the engine.

    Plus if you set the engine to 62.5-63hz. and replace your oil right out of the box with 5-50 Quaker, your off to the races welding wise....
