Issues after rebuilding a XP 720
Hi Everybody, I have just finished rebuilding an XP 720, new hot rods crank, new wsm pistons (stock size) , one new cylinder, both cyl freshly honed... Cleaned the carbs, replaced all the fuel lines and vent lines. I got the carbs set to 1 1/2 LS and 1/4 H/S, which i believe to be stock, and the engine runs away on me, not even pulling the safety cord stopped it, had to pull the choke to kill it. so now it starts up and idles fine but if you give it any gas it runs away.. So I went richer and richer on the HS til it seems to run decent, but i'm really concerned as to why its doing this at the stock settings...
Any ideas would be greatly appreciated!
