Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Model number 917.257561 18 HP Twin Cylinder We seem to have to crank and crank. We changed the spark plugs and installed a new 300+ CCA Battery. We are unsure if we should choke it until it fires or not choke it and see what happens. We have it at WOT and choke it. Once it is going it seems to run fine. Should we try an "add to gas" engine cleaner (Gumout Seafoam, etc.)? On a side note: We are looking for ways to add weight to the rear to balance out a front snowblower. THANKS
