Fuel problem ???
Montauk in 3.....2.....1

its not a fuel problem. thats what i thought at first and twice i put fresh fuel and ran it through but i kno it wasn't bad fuel.

carbs could be gummed up. has it sat up for a while?

Your jets are likely clogged. They'll idle all day but under a load, they choke out. Time to get some carbs cleaned

i had jus had them cleaned a few months ago and i didn't leave it sit up that long since. i will most likly bring it in this weeknd if i cant figure it out but id hate to pay n get them cleaned again. somebody jus told me that it could be the power pack goin bad:confused:

If you had the carbs dome, did u have the lines(fuel) done too? If not, it's like you never had em cleaned. I don't see power packs as the problem. It wouldn't want
to run at all if so.

By done, I mean, did u change them? They have a tendancy to break down as time wears on and they say that ethanol accelerates that process.

im not to sure it they did the fuel lines to. ima have to see about that, thanks

i pretty sure it is a late 80's motor but not possitive. what you mean by points? im not the best motor wiz

thanks D ill have to gve that a try

sounds like jets in carb, gas goes bad in 3 months, any longer it turns into a thick syrup like crap! for future reference, i'd run all the gas out the carb after every fishin trip and use stabil! walmart fuel lines suck most older hoses aren't alcohol resistant and the ethanol in gas will rapidly break the hose down and junk your carb up! this could be another problem.

Its not Carb issue....Its your plug wires.......I had the same engine......plug wires....

carbs sound like thr problem but as i said i jus hadem cleaned. about how much were new plug wires if you remember? thanks

do you remember what the plug wires cost by any chance?

Carbs are probably varnished, Oreilly has ChemDip. Get a gallon and soak the carbs for 2-3 hours, this will probably take care of your issues. I will never pay someone to clean carbs again, it is that easy.

how hard is it to take the carb out? i never did work on the motor always brought it somewhere.

Its not cleaning hem that's hard, its getting them synchronized again if you mess up........wires were about 20 bucks for the build your own

alright thanks

Just drop the whole thing in or do you have to take it apart?

Most of the time you can just pull the bowls off and soak the bowls and top halves. Get some torch tip cleaners for the jets.

don't put gaskets in the dip!! Eats them up! all plastic and rubber!

I just pulled the bowls and used carb cleaner last time. No gasket worries that way. Use the hard attachment to spray the jets.
Also, use safety glasses cuz carb cleaner burns like fire!!!! Happened to me twice! Guess I'm a slow learner! Lmao!

Take the gaskets off and drop them in the cradle and into bucket. Chemdip was not very harsh,second the spray cleaner Corey. That **** will de-fat your skin fast.

here is a question no one asked, I had the same problem today! my carbs are clean, I just didn't have any air going in to the gas tank, I could idle but as soon as I would gas it, it would die, I opened the top to the tank and then put it back on without tightening and my motor ran fine after that.

Gas tank story......

I was cleaning the back of the boat a few years ago. Before removing the gas tank, I closed the vent to keep from spilling any gas. You guessed it......I forgot to open the vent when I put the tank back in the boat.

I went on a short fishing trip and only burned a couple of gallons [6 gallon tank]. When I stopped at a gas station to top it off, the tank looked like a prune....it had caved in. I don't remember if I put any gas in the tank or not. When I took the cap off the tank, it stayed all caved in.

When I got home I put the tank out in the sun with the cap on. When I checking a couple hours later, it was back to normal shape.

My outboard engine had run fine that day.

Ethanol is alcohol, so it will clean parts and your fuel lines from any varnish acumulated over time in your lines and any thing else along the way. I am dealing with the same thing right now!!

mix 2cycle oil with that ethanol enhanced gas and it won't clean crap! I haven't heard one outboard mechanic ever say anything good about ethanol other than they're making a crap load of money from repairs due to people buying gas with it!

i agree!!! i just got some new plugs and should be geting the new wires this week. ima also clean the carbs since i have someone to help that did it befor

ok guys now im lost. i took the carb off and cleaned it and put new plug wire and plugs in and got a new gas line and it still dont wanna run good. it will idle till the gas tanks empty but when u give it gas it wants to kill every few time. any ideas??

Power pack

Adjust your idle...happened to me in hopedale once

is their a way to test the power pack or somewhere that does

have you done a compression check and a spark check yet?....compression,spark and fuel are the 3 things needed for a motor to run....always run these 3 checks before you start tearing into a motor and shooting from the hip.....it will save you alot of time and money. you can buy both compression checker and spark tester at autozone for around $30


do a spark check to test your power pack/electrical system....set the spark tester to 7/16 gap..if you dont get a strong blue spark at 7/16 gap..you got an electrical problem....and then you can go from there......also try to warm your motor up before doing the spark check..sometimes a short in the electric system won't show itself until the pack /wires are warm.

compression check....should be over 100..and each cylinder should be within 10% of each...again...best readings are done when motor is warm....

fuel...check/change your diaphragm in the fuel pump....cheap to do....you can also check this by when your motor starts to run bad or want to die...pump the bulb...if the motor starts to come back to life change your diaphragm ....good luck
