Hello, I bought a 64 MFG 17' VHULL w/ a 1978 Evinrude 70HP the end of last season. I took it out for a test run before buying it. It started up fine first turn. Last fall I fogged the engine. This spring in prep. I changed the plugs and oil. Last week, took the boat to the ramp and took a few tries to start but we got it running and well. So, we took it to the slip for the season. Next day, can not get her started. She cranks but won't turn over. Tried new gas, put old plugs back in. Noticed that the gasket leaking fuel on the intake. But can that cause her not to start? Possibly the choke is not getting enough suction? Please help!
