Hello Dan,after much research,I found the engine is missing throttle parts,and has a worn-out throttle control rod in the carb.I tried to order the part thru my cub dealer,But,after 4 month's of no reply from B&S,this project is now in LIMBO.My cash flow is also down,no overtime for 09,maybe next year,Thanx again for the info,sometimes the obvious is hard to see!
