no fuel on sparkplugs

[Gibb]

I have a 1981 85hp chrysler which has been sitting for about 3 or 4 months, the last time it ran fine! I know its a no no but it will run with spraying starting fluid in the carbs. I pulled all 3 plugs and they were dry. Any help would be appreciated

Re: no fuel on sparkplugs

Well, you have at least 2 options. You can continue giving it ether 'til it blows up and go get a new engine or you can go to the Engine FAQs Forum and do "Outboard won't start".

Let us know what you find. My guess is that you are getting no fuel to the carbs or that all carbs are gummed to death.

Thanks JB,
Last night I pulled the fuel line off the lower carb and turned the moter over and plenty of fuel came out. My guess is like you said, the carbs are propably gummed to death. So I pulled them and my next question is how far do I break them down to clean them? Thanks, Gibb

Need advice from a Chrysler expert on that, Gibb.

I would first go get carb overhaul kits, a jug of carb cleaner and a Service Manual.

Syloc is a bad choice. Get either a Clymer or a factory manual. Seloc has more mistakes then facts. Pull the idle mixture screw out and work that area inside the carb with WD 40 with a spray straw. Put the screw back in turn till lightly seated then turn counter clockwise about 1 1/8 turn and see if that helps. Look in the float bowl and see if you see any sediment. Could be your rubber hoses and rubber diaphragm are starting to deteriorate. If cleaning the idle screws works get all new hoses and a diaphragm for the fuel pump.

I can vouch for that, at least in the case of my 20HP.

Re: no fuel on sparkplugs

Thanks for the tips, I will let you all know what I find. I live in south east Fla and I'm starting to prepare for a posible hurricane so little time for carb work. Thanks again for the help! Gibb

Re: no fuel on sparkplugs

I cleaned my carbs and put new fuel lines on. Checked the fuel pump, it was good. I screwed the idle mixture screws in all the way, then backed them out a turn and a quarter. Boat started, but backfired quite a bit and can't stay running more than minute or so. Adjusted idle mixture screws until it did not backfire, but engine sounded different like too much fuel. Not sure about idle mixture screw settings. Gas spitting out of top carb. Compression tests showed all at 140-150. Not sure of next steps!!

PS: Looks like hurricane is heading south of us

Put the carb mixture settings back to 1 1/4 turn. Verify that the spark plug wires are going to the correct spark plug. Worst case on the mixture would be 1 1/2 turns out. Anything more then that there is something else wrong. Backfire is usually timing and because static timing is almost impossible to go out and you did not hit anything last time you had it running chances are the plug wires are reversed.

Re: no fuel on sparkplugs

I have taken the wires off and on so much Im not sure of the righ order of the wires now, but I have it running the only way it will stay on but its very rough.

Thanks, Gibb

Motor is back to life. I had the #1 and #3 wire switched, runs a lot better than 4 months ago. I appreciate everybodys advice and it cost me under $10.00. Best part is no hurricane!!

Thanks again, Gibb
