Does it have a throttle return spring, and did you attach the throttle linkage to the same hole as it was on the old carburetor? Sounds like it could just be binding linkage. I'd say a governor problem but it sounds like it didn't have this problem with the old carb.

      HELP! D-Series Clutch
      By BuffaloD200
      '74 D-180
       
      My friction disc in gone on my clutch.  I saw the old post about making a new friction disc, so I'm not concerned about that.
      I managed to remove the front clutch plate and double v-belt pulley.  But I can't separate the two.  When I took the assembly off the spiraloc washer popped off on its own.  I HAVE READ THE MANUALS.
      So I should be able to just remove the pulley from the front clutch and continue with step 4.  The v-belt pulley is loose as all hell and flops around like a dead fish.  It seems to be hung up on a ring or bearing race.  
      So my thoughts are grab a BFH or sparky the blue tip wrench.
      Is there an unpublished step 3.5, or some trick?

      8-25 Riding mower belts
      By robertsonchris06@gmail.co
      After using my 8-25 mower successfully for several years I noticed the belts were very worn. I replaced the belts and used the mower several mowings this past summer with no problems until as I was mowing the last time the mower would not move in any gear. After stopping and inspecting the traction belt it was almost completely destroyed. Prior to this I had noticed that the engage/disengage lever was getting hard to activate (very stiff). Has anyone had a similar thing happen?
      Thanks in advance for any help on this problem.
      Just want to keep my mower running.

      I’m trying to restore my grandfathers old 252-H to use around my property. The tires are shot and the rims aren’t too far behind. Anyone have any recommendations for rims and tires that would fit well on it? 
       
      right now it has 22 x 7.50 - 12 on the back and 15 x 6 - 6 on the front.

      Snow thrower help
      By 87buickt
      Newb here, recently purchased a b310 that now runs with snow thrower, plow, and mower deck for what I believe to be a good deal for $200. My question to all y’all gurus is what am I missing for my snow thrower attachment? I’d like to get it squared away before winter I know I’m going to need a belt and chain any help would be greatly appreciated.
