ok i have the engine and boat the boat isnt built yet but ive had the engine assemled for a couple days and have not been able to keep it going im using gel chaffing fuel and it just doesn't seem to be making enough steam to keep it going i put a fuel line cut off from a nitro vehichle on the hose so i can keep the steam away from the engine so it has time to build up then i release it and it will run idf the piston is in the right position or with a flick steam goes everywhere it seems to be coming out more everywhere other than the exhaust port some does but it dosent seem like as much comes out there as other places it will run for a while until the pressure gets low. please help!!! what am i doing wrong?
