Engine runs fine but boggs down under load

Had my '78 D-200 (K532 engine) w/snowthrower out today and found it lacking in power. The engine starts and runs fine but when I attacked the snow the engine RPMs dropped off quickly. The snow was wet and heavy so I didn't chage in too hard. I got the job done but it deffinately wasn't as strong as it was last year. I believe I have to adjust the carburator. Can anyone tell me if the engine is running too rich or too lean?

Thanks for any assistance,

Kevin

Sounds like the governor needs adjusting.

I would try giving it just a little bit of choke - if that helps it then its too lean, if it hurts it then its too rich.

Then you get to work out whats different from last year...

      1981 GT2500 Snowthrower Models
      By dave who poos
      Hello!
       
      I am looking for any and all snowthrowers that will work on my GT2500. I am trying to find one off FB marketplace but no one ever really posts the model number. Usually just the length. So I look for 42'' throwers but I don't know what will fit. A local seller has this for sale:
       
      He says its 42 but unaware the model, the Wheelhorse logo looks to be from the late 60's/early 70's? It looks like the below thrower:
       

       
      My question is if that thrower year/model will fit the GT2500. It looks pretty dang simple but I'm not sure. Someone mentioned something about the right size "Quick-hitch" in another post.

      Used my 79366 snowthrower twice and it broke...need advice
      By bizzo15
      So long story short I scored a two stage snowthrower for my 520xi in the off season and hooked it up to my tractor and finally got a chance to use it this past weekend after we got a storm that dumped about a foot of fresh now.  First time out everything was going good and the snowthrower was moving snow like a beast, I did notice though when I got to the berm at the end of the road the blower would shake and vibrate pretty good when going through it.  I thought it was just normal operation since the snow tends to be more compacted from the plow, I just made sure to go nice and slow when I got to the end of the driveway and was able to clear my driveway and the neighbors without any issues.  Fast forward to the next day and I fired up the tractor to clean up the driveways as we got another couple inches over night.  Was able to finish my driveway but halfway through the neighbors when clearing the end of the driveway the blower shook and the suddenly stopped.  I shut it down and looked around and noticed the belt was broken, I didn't think too much of it as when I put the blower on the tractor the belt was showing some wear but when I saw how expensive the toro belts are I decided to run it as it looked like it would make it through another season no problem.  Once I got it back in the garage I removed the belt and that's when I noticed that something didn't seem right, the spring loaded pulleys on the right side of the pulley box were hanging below the blower frame, I took the chain and belt cover off the blower and noticed there's damage to the main belt pulley on the blower as well.  I pulled the pulley box off and noticed that there's groves worn into the metal from the pulley and what looks like some belt rub.  Anybody have any clues on what caused the belt to fail?  I'm including pictures to hopefully give some clues to those who have used these blowers extensively.  I followed the manual while installing the blower but I'm wondering if maybe I don't have something assembled correctly or am missing some crucial part.  I'd really hate to spend the money on a new belt only to have it blow because I didn't correct the actual issue.  I will say all the bearings seem tight on the blower and there doesn't appear to be any play in the shafts.  I look forward to any insight you guys can offer, thanks.

      Snowthrower question
      By 608KEB
      The tall chute snowthrower on my 520H  will twist the kotter pin and disconnect from the lift rod.  I've  also used  kotter keys with worse results. Has this happened to anyone else? I do have 2 washers on the end of the lift rod. Adding maybe 1/8 of a inch to the total length  of the lift rod.  I've  never had a problem  with the short chute snowthrower  that I have hooked up to my B100.

      Snowthrower chain lube.. What to use?
      By Navig8r
      I picked up a used single stage that has been sitting.  The auger spins, bit things need a little TLC.
      What chain lube have you found to work best, and last longest?
      Any lube needed on the bearings? Or just replace if stiff?
      Thanks!

      D series Kohler twin battery sizes ?
      By Sarge
      Ok - the UL-1 batteries won't cut it for turning over the big cast iron Kohler twins - got one that is only 6mo old and it's basically shot already . One start cycle and if it doesn't fire it's done - needs to be jumped . Since it's mounted above the Sundstrand pump and so close to that thumper engine I'd assume the vibration is just killing the plates . At a rate of 2 batteries per year - that doesn't work out very well and the rotating mass of that engine just draws far too much from the battery - even with a new starter .
       
      From the BCI group number chart and some dimensions of what can fit in the tractor physically I come up with a Group 26 battery - what is everyone using in their twin cylinder D's ??
       
      I see an equivalent Deka runs about $80 - anyone tried that size on one of these D's ...?
