Well I think I found a carb.that with some modifications might work.The carb. in question is for a snowblower,gen.,etc.The throttle shaft will have to be swapped out with mine.Now the Eska has the fuel tank above the carb.as it stands & does have the duck bill pump.My concern or question is,if I block off the hole (where duck bill is) with a gasket do you think it'll still feed as it should? Also the new carb.has a primmer bulb connection that in my mind is not necessary if the choke is used,so I in theory,I could just block it off.What ya think??
