I have a 12hp kohler that when its running it pops threw the exaust and you can see a small amount of flame in the muffler. What does this mean and how do I get it to stop? Thanks Paul

What are the points set at...they should be .020 but some horses run better at .018.  Anyway, it is a sign of running rich or the fuel not getting burned all the way.  The points take care of the timing...then it is on to the carb.

I also have a 8hpm Kohler and I put a new fuel pump on it and it won't pump fuel. So I bypassed the pump and just had the fuel line gravity fed. Then the motor ran rough for about twenty min; Then stalled and when I tried to start it again it would just turn over and Then go bang. I dont know if it was coming from the carb or exaust but has'nt run since .Where do I go from here.

Pictures of both fuel pumps would help and what horses we are talking about.  Pictures of the carbs would help also.  The more you can show us, the less we have to guess.  :occasion-xmas:

      Raider 12 replacement battery winter
      By mmmmmdonuts
      My cheap-o walmart U1 battery is starting to bite the dust again (barely able to crank it over fully charged, and ozzing everywhere) after 3 years on my 68' Raider and I am looking into a new battery for winter as I now have a plow setup. I was thinking of either getting the original 22NF battery that came with it or running a mazda mita battery which is a U1 size. Is the AGM worth the extra money over the 22nF even in the smaller size? I think the vibrations keep killing the cheapo batteries and I am trying to make sure I can leave it out in the cold and not have a problem starting in the winter. It does get down to 0F or below zero every once in a while. I don't think I want to go all the way to a 22nF AGM as it is $200. 
       
      Thoughts?

      Solid tires
      By Raider 134
      Hello, I was sondering if anyone knows if it is posible to mount some solid rear tires on my raider 12? I use it like a work horse(pun intended) and im constantly running over nails and screws and getting flats, The worst part is that the tires are not tubless so it is a pain to get a new Tube and fix it(because delivery takes a couple of days if not even weeks) so i could use some solid tires but id prefer to keep the original rims. So if anybody knows if it is possible please leave a comment!.

      A couple more tractors + a tiller.
      By rustyoldjunk
      You may have seen my "scrap yard save" thread that I posted last night. Well I also done a little tractor swapping with some tractor buddies and ended up with these Wheel Horse tractors. A C161 hydro and a best I can tell 68 Raider 12 ( I haven't ran the tag on it yet.). Also got a nice 42 inch RD deck and a nice tiller. Both tractors seem to be in very good shape mechanically. The Raider is missing the hood and engine but it did come with a good K321 14HP long block. The 161 needs a little wiring work and an axle seal.
