I have heard of other people having the shut down problem, and I have found out that mds now has an after original purchace C2 carb, the current carb sold on newer engines. I bought this thing 4 or 5 years ago, bench ran it till out of gas and stored it till recently when I put in on the Hog Bipe. Considering getting the newer carb, anyone know anything about the C2? Also, what do you 'spose the chances of Horizon springing for a new carb, since the first was messed up? Thanks for the replys.
