Sorry to tell you but you need to go back into the carb you put the wrong nozzle gasket in, it's the big o ring same color as the bole gasket and it looks like you forgot to clean the hi speed jet.
Thanks for the advice. It is on my list to go back to carb. I do not think there was a nozzle gasket in the kit. That is why I picked the one that I did. I'll check the high speed jet too. Thanks for watching.
@@TheGarageEngineer There might not have been one in the kit. I have had a lot of problems with Sierra parts like kits without all the parts, I will only use sierra for gaskets and seals. The nozzle gasket is #36 here www.marineengine.com/parts/johnson-evinrude-parts.php?year=1965&hp=3&model=3503&manufacturer=Evinrude§ion=Carburetor+Group
and the hi speed jet is #39
I would highly recommend using the Evinrude carb kit part number is 439071
www.marineengine.com/newparts/part_details.php?pnum=OMC0439071
I would also recommend replacing the points and condensers because they are original hear are the ones from Evinrude www.marineengine.com/newparts/part_details.php?pnum=OMC0172522
@chrysleroutboarddude I found the gasket that goes around the nozzle and matches the bowl gasket. I can't get the high speed nozzle out but I can see that it is unobstructed. I don't think there are any side holes on the high speed nozzle so that should be ok. But i m leaking fuel out the intake part of the carb. Any idea? It runs but only about 8 seconds then dies.
@@TheGarageEngineer maybe the float is stuck in some way, or the fuel inlet meter valve or seat compromised or have crud stuck in them? are the flanges flat? look around the float area, i would suggest, however, I'm no expert.
@@MikelNaUsaCom I am working on an update video. The short of it is the float angle need adjustment down. The float was not shutting the needle off soon enough. Thanks for your advise.
I like the honest way that he does his instructions. It is also nice that he goes into details with his presentations as most viewers are people like myself who does not have that much knowledge of these things.
Nice!
It was a fun project. I have 3 more waiting to be revived. Thanks for watching.
I believe he gasket you used for the “drain” actually goes inside the carb on top of the jet you removed in about the center of the carb. The gasket seals the top of the jet when the two halves of the body are screwed together.
I’ll have to take it apart and check it out. Thanks for watching.
I had a float pin that was hard to get out also, I mounted it back on the intake upside down and punched it out. Just some helpful info
Good idea. Thanks for watching.
I'm glad you got the exhaust on the carburetor ok , hahahahah
😅
Just to note: Use a Cordless Drill on the top nut is a little easier to test. Make sure you go the right direction.
Thanks for the suggestion. I will try it next time.
make sure you replace the waterpump impeller. i imagine it's shot by now they don't age well. it's an easy job.
Done. Thanks for advise. The impeller is very important. Thanks for watching.
Can you do a video on what the two knobs that have the numbers and lean on them do and how to use them correctly?
Good idea. Let me see what I can do
I was about to mention the 2 packing nuts but I see you discovered it
People talk too much crap... Looks like your learning, not a bad thing. Seat gasket is always fiber. Should use air hose to plow out passages as well. But ya, keep learning I know I always want to expand my skills.
Let me fix myself seat gaskets are usually fiber but can be brass or another soft mettle as well.
Thanks for the kind words.
The kit should have everything you need
to get any of those orifices out you need the tool i think it's 317002. even with the tool i have stripped many of them from the brass welding itself to the aluminum.
You should have got the kit with new jets and floats and needle
You should run fuel in the carb it the only way the crank shaft and the piston pin gets oil.
Thanks for the advise.
Good luck
This carb just has one needle the earlier ones had a low speed and a high speed needle each had it's own adjustment I guess that one needle is doing the job of both?
Some models only came with the upper, low speed adjustable jet. My '67 owners man. States the high speed jet is set at the factory and is not adjustable. My '68 has the two adjustable jets.
@@brianchisnell1548 thanks I was wondering I guess you just clean out the lower jet then
Make sure you bring a paddle
A lot of the parts like jets come new in carb kit
He's learning making many mistakes, I did to my first time but for cleaning carbs use a sonic parts cleaner much better. I do give an A for effort though.
Thanks for watching. I wanted to go throught those steps because it helps me familiarize myself to the motor and its parts. I would love a sonic cleaner. Maybe next time. But the low fi way of vleaning worked. The carb wasnt too dirty.
Believe me I know mind you I took a carb off a motorcycle with me while fishing and cleaned it with just carb cleaner. To many beers and fish it amazed me that I got the thing done without losing something and the bike purrs like a kitten. Will not try that again whoaa LOL
Oh boy....
👍👍💰
Why didn't you use some kind of gasket sealant like perma tex to help the gaskets seal better. I have never replace a gasket of any kind without using perma tex or some kind of gasket sealer to prevent leaks on new gaskets? Why did you not watch you breakdown of the gasket to see how it goes back together?
Factory didn't use gasket sealer so I didn't either. The gasket wasn't the problem. The float was not adjusted correctly and was not shutting off fuel flow. And the leaking was coming out the main jet.
Not on a carburetor....
You never use gasket sealer on a carburetor. Ever.
In sorry but I would hardly call you the garage Engineer,but not a bad diy effort, sort of nearly got there in the end
The claw hammer tells me he has no real tools.
He's learning. That's good enough for me.
better take care of other things ... it's not yours !
?
real bodger

I am 14 and have only began with engines one year ago but still have more expirience than you 🤣
Maybe now that you're 17, you might have learned to be decent.
