1959 evinrude 10hp

[coolguy147]

sheesh this has been going on for a very long time. my motor is really hard to start even when its 85 degress out side. take me maybe 25 pulls or more. i think my motor might be flooding some how but im not sure. ive cleaned the carb a lot before. got a fuel filter in. adjusted the carb. last time i ran it i didnt run the high speed needle all the way where it should be and i gained some 1-2 mphs from just makeing it a little bit leaner. i noticed that after i kept lean sneezing at idle. so i said i will ahve to adjust the idle again. i have it at 1 1/2 out. when i do get the motor started after i clean the plugs a bit which r wet i guess cause i can put them on my hands and press then i see a oil out line and gas. but after i clena them i choke the motor it starts in 2 pulls. whats wrong? i cant think of it? air leak aming hard start? ya and by the way i think the lean sneezing stops at idle when i run the motor at full throttle maybe 1/2 -3/4 a bit? but this shows its a dirty carb? checked spark again i got nice even blue white spark and its alternating good not mis fire.

only thought for the hard start is i ahve a problem with my choke. i have to use a cloths pin to keep it closed. and it opens just a little before i noticed when i start it. but today after each time i pulled it i made sure the choke was closed all the way. and still nothing. i reach wide open easily.

what u guys think?

Re: 1959 evinrude 10hp

just looked int he outboard wont start post. i narrowed thigns downa nd only thign that could be the problem as said in that post is carb to maifold not sealing or i have a fialed needle. would a failed needle cause flooding?

i have the sierra kit needle in there? i forgot if its metal or rubber

Re: 1959 evinrude 10hp

A bad needle valve or a needle valve with a tiny piece of trash between the needle and its seat would cause it to fail. From my experience, you can tell if it's failing because you'll never feel a "firmness" when you pump the primer button until the needle closes off the fuel to the carb. That would flood it and make it nearly impossible to start until you dried the plugs. You should also probably see fuel come out the overflow vent if you keep pushing the primer. If the needle closes right, pushing the primer won't let any fuel in once the float bowl fills to the right point. A gas-logged cork float will do it, too. Also, a choke flapper not closing all the way would make it very hard to start. There could be a little nylon square thing that the choke knob fits through that's missing and not holding the choke all the way out, but I forget because it's been a while since I've worked on a '59.
One thing's for sure, with 90 or 95 lbs. of compression, if you get it right it WILL start in two pulls cold.
Good luck,

Re: 1959 evinrude 10hp

ok so the needle problem is solved. caus ei pump it up that thign aint pum,p up anymore soon. and i replaced the cork float with a new one by the way.

i guess i maybe missing some parts in the choke to function right? so that i guess solves my hard to start maybe? now what about the lean sneezing when i first start here up.? any thoughts

we have had this dicussion before "caus ei pump it up that thign aint pum,p up " spell check!! no text terms. i have no idea what you are saying. quite being in a hurry and read what you typed, before you post it. i learned the hard way also.

I agree. Very hard to read.

i have the tendency to press the space bar a little bit early

what i was saying is that i can pump the primer up maybe 5-7 pumps it i cant pump it anymore so my needle must be working and float and after i try to start it i cant do anything

Re: 1959 evinrude 10hp

what do you mean, you can't do anything? all the 10hp has on the choke linkage is the pull out bar, that connects to the butterfly lever.

Re: 1959 evinrude 10hp

just forget what i said about that. to the facts is that my choke lever wont staty out on its own

Re: 1959 evinrude 10hp

If it runs well wide open, and idles smooth and low, then the problem should be your choke not closing all the way. Is your motor idling smooth and low when you get it started? If so, then it's the choke. If not, then your low speed circuit is not clean, your float is improperly adjusted, or your slow speed needle is either grooved at the tip or not packed properly.
If the only problem your motor is having is not strarting easily, then your choke not closing all the way is your problem. The most likely thing is that the nylon friction piece (if your motor has that) is not working or not present.
That's about all I can think of.
Good luck,

Re: 1959 evinrude 10hp

ill take a look sometime. but i think that when i started it yesterday it would sneeze at idle and stuff. i havent had the chance to take it out at high rpms with the new adjustment. but when i did adjust it before i acaully adjusted the low speed after it would lean sneeze going through the canal coming home

Re: 1959 evinrude 10hp

If it's lean sneezing, either the low speed circuit isn't clean, your needle is grooved from being tightened too hard, or it's not packed good enough, or you have a vaccum leak somewhere.

ok well i put two packings in and its pretty tight in there. ill have to recheck the needle again. and the manifold gasket i will look at sometime. hopely i wont have to take my carb off again

Re: 1959 evinrude 10hp

well i havent gotten to take a look at it lately mainly cause ive been sick lately. but i have been thinking about it. well im want to talk about the lean sneeze at idle when i first start up. right now the needles r at 1 1/2 out. well if it doesnt sneeze anymore at 2 turns or even 1 3/4 turns out. u think that could ahve been the problem?

Re: 1959 evinrude 10hp

1 1/2 half is a starting point in adjusting those carbs, depending on the motor and the carbs, it can be as much as 1 turn in or 1 turn out. adjust till it does not sneeze.

Re: 1959 evinrude 10hp

The choke lever needs to work properly. If it disengages as you pull the rope it is doing no good. You will have a heck of a time getting it started. In fact, the motor will probably flood out before you get it started. If the choke is sliding back in then you have a problem with the linkage. I'm not familiar with the 1959. It either has a detent or a nylon friction bushing that keeps the choke lever out. You need to fix that problem.

You turned the high speed in to the point where it is lean at WOT. This also effects your mid-range fuel flow. It can cause sneezing. 1.5 turns on either jet is rich. Is the high speed turned out to 1.5 turns as well? I suggest you start again. Set the high out 3/4 - 1 turn and the low 1 1/4 - 1.5 turns. If you have to have the high speed out 2 turns then something isn't right. We'll come back to that if its a problem.

Resist the urge to run the motor lean at WOT. Find the spot where it runs the best/fastest, then turn the needle back 1/8 turn on the rich side.

Re: 1959 evinrude 10hp

ok well i didnt go ahead and adjust the needles again. but i did take the high speed needles and turned it about 1/8 of a turn out and that basically fixed the problem of sneezing. thanks i left low speed needle out at 1.5 turns out and that was a good spot for it.

oh ya i found a spot on the choke area where i can stick a cloths pin and it will make the choke lever stay closed and not even move when i turning it over. so thats good but turns out i was missing the piece where the choke lever comes out of the couwling and its missing something like a friction item to hold it open?
