Gentlemen, I have a very low hours 1991 S16 w/ 302, 2 barrel, all stock. Bought it last year with original white steel trailer and it ran great the few times we had it out until Sandy forced my hand. Put it away in non-freezing garage with treated half tank of 91 octane fuel. Did not put it in till early fall this year when I finished building new dock. Filled with fresh fuel. Starts right up and idles fine. Took her out and about 20 seconds after plane, engine dies out. Starts up and does it again. Finally brought it back at idle. Carb was rebuilt but removed and cleaned anyway. Emptied and changed Fram fuel filter. Emptied fuel in jar- no debris or water. Emptied fuel tank to dry. Pulled fuel pipe from tank and found that strainer/sock was absolutely clean. Carb strainer clean as well. So unless I missed something I've ruled out fuel.
I bought new plugs and am now looking for a special tool to change them. Man, they didn't put a lot of thought into that design. I don't think it's the plugs though.
I may have and probably did leave the key in the on position inadvertently last fall. I'm told that can effect the points.
q1. It has a factory standard mechanical fuel pump which Im told will either work or not work so that can't be it, or can it?
q2. The coil and distributor look original. Could one of those be the problem? A bad coil for example?
q3. could it be the points?
I could just start replacing things but id prefer to find the route cause and so here I am.
I'm new to the site. Any ideas?
