Changed the bulb. Still doing the same thing puttering and shut down. If choke open it runs little longer.

your engine is telling you it wants fuel ...

hand pumping is not the solution.... it is an indication your pump is not
sucking gas from the tank and not pushing it to the carb !! If the carb was full of fuel the engine should run longer but does not an indication the pump is not filling it or possibly the float was not set level to the carb edge when held upside down. recheck and adjust if not done and also......DO A BLOW TEST ON THE CARB!!

"Didn't do the blow test once done but fuel is coming from pump exit when I press the bulb."

make certain the pump's back sealing gasket is installed and the pump passes the blow test. check venting open the tank cover


normally a fuel tank sits about 12-16 inches below the power head.... sitting on the ground can be a heavy lift for your square pump. the tank can be 10 feet away but never 4 feet down !!!

lift it up to be a foot low , prime the bulb, pump and carb and retry.

 

[Mohsin]

Thanks. I will redo the pump tomorrow.

 

[Mohsin]

I did the pump done three times but did not work. Getting my interest lost kind of situation now. [-(

 

[Crosbyman]

Did not work meaning what..... blow test failed ??

Why don't you try a new pump.

That kicker looks real clean and giving up on it would be a shame. Reassembly (orientation of parts) is confusing the first time around.

 

[Mohsin]

Blow test pass. Everything looks so clean in and out. Don't know what to do. I did pump 4 times. Only start in choke fully out. But shut down right after even choke is pulled. Not even start without choke pulled out.

 

[Crosbyman]

I restarted and keep pumping the bulb than it keeps running.

hand pump it again and make certain the tank is ABOVE the engine

try to start it...

if it runs the pump is faulty install a new one . (up to you $$ ) The only reason the pump would not work is that the crankcase pressure pulse on the cyl downstroke is not reaching or strong enough to work the pump.

remove the pump as a test and put your finger on the engine pulse port
have a buddy crank the engine ...you should feel the air pulsing. if not crankcase is loosing back pressure.. could be bad reeds or crankcase seals which I doubt.

other opinons welcome ! and by the way did you confirm you have good strong sparks on both plugs what compression #s did you get

 

[Crosbyman]

btw you have electric start ... why not hook up a battery and get it going.
very basic circuitry find the solenoid and follow the small control wire to the start switch !
basic for 1984 should be similar to yours even if earlier model.
yellow red to solenoid should activate the solenoid the rest is for charging the battery and firing the coils so focus on the solenoid-starter

Thanks. I did put up above the engine still the same issue. Will try to test engine pulse port next. Spark plugs are little black when I pulled them out.

I don't have marine battery but the car battery. I can just touch +ve and -ve it will start?

 

[Crosbyman]

fuel tank above the carb...

connecting a battery involves basic knowledge of outboard electrical cct

suggest you red up on the subject battery must be connected to the large red and black cable red is +

then you need to activate the solenoid that transfers battery power to the starter for a few seconds ( max 5 seconds ) at a time . like Racerone says.. I am not there nor can I see what you have or don't have so you need to read up on thus stuff.

in the mean time try with the pull cord with tank ABOVe the carb and fuel pumped till the bulb is HARD indicating the carb has filled up with fuel. .

 

[OptsyEagle]

Have you tried a different fuel hose?

 

[Mohsin]

Have you tried a different fuel hose?

I bought new bulb but not the hose.

 

[OptsyEagle]

Another thought. When you cleaned the carb did you put the little clip on the inlet valve to the float.

Sometimes those inlet valves can stick and they came up with that little clip to make sure the inlet valve will get pulled out of that passage way to allow more fuel to enter the carb as the float drops from fuel usage.

I will check. Thanks

Of course you also want to look closely for any signs of air leaks. That will also prevent fuel from flowing to the carb but I would think you would also see fuel leaking when you prime it, but take a close look at all the connections anyway, and look at the conditions of your tank's fuel hose connectors, etc. Hopefully you are getting a good seal when you connect the fuel hose.

 

[Mohsin]

here is the carb.

 

[Mohsin]

Its get started now without choke but still keep shutting down after few minutes. Upper shaft get hot and white smoke is coming from the exhaust.
I still need to pump the bulb while tank is upper than engine to keep it running.
Also I don't see any air pulsing feels when put finger on the port while starting.

 

[Crosbyman]

feeling for the crankcase pressure pulse is with the fuel pump removed ! and someone pulling the starter rope for you.


if you fell no pressure pulse out of the engine side fuel pump pulse port the pump will never work .

can you take this kicker in a good shop ?

 

[Mohsin]

There is local shop here in Calgary Automarine. Unfortunately they don't accept any outboard before 2010. There might be solo mechanic on kijiji or facebook but they are charging more than the shop. Might sell this AS IS.
