For the Ivermectin, 1.87% should be pretty good for the common things in horses like bloodworms (strongyles), bots (gastrophilus), and roundworms (ascarids), but of course you should always consult your veterinarian before medicating any pet
, especially since I am still just a vet student. Zimecterin (not Zimecterin Gold though) actually has 1.87% ivermectin as the active ingredient, and it really is worth the money to talk to a vet about setting up a parasite control program for your horse. They can make sure you are covered for whatever parasites you may have in your area and set up the right timing. That way you don't end up buying and giving things you don't need or using too much of it by using it too often.
About the Holley 750 idea: has anyone run a holley squarebore on a spreadbore manifold? Also, Summit has their brand 750 with an electric choke for $235 right now and they look just like a Holley to me. Anyone know anything about those carbs or running one on a spreadbore manifold?
