Hello, I have a 1976 Johnson 70. Model# 70EL76D<br /><br />I have been trying to resolve an idling and full throttle issue. I have cleaned and rebuilt carbs,changed fuel pump,changed plugs,checked compression and made sure all cylinders were firing.I am now in the process of replacing reed boxes and reeds. MY question is - Do I need to put any gasket sealer on the new intake manifold gaskets? And if so, Can I use HI TACK Permatex? I have a Seloc manual but it doesn't say wether to use sealer or not. Thanks for any advice!
