my 200hp johnson takes a while to start, but after it starts it runs like a champ all day. if i let it sit for two days and try to start it again, it takes about 3 to four minutes before it starts again. any suggestions on how to rememdy this. i have changed the spark plugs.

Jessielsmall,

pump the prime bulb tight.
Try to push the key for few seconds (if you have a push to choke) before starting the engine. If the push to choke is not working you then try to release the lever (just above the electric primer solenoid)

Good luck

Re: 1991 johnson hard start

Try the 4 step method. Now this is assuming the motor is healthy (including the primer system) and has the correct spark plugs etc.

1- Pump the bulb. This pressurizes the fuel delivery system.
2- Turn the key to the "On" position, do not engage the starter.
3- Push the key in and hold it in for an 8 count. This opens the primer (you don't have a choke) and allows fuel (that's under pressure) into the intake.
4- Turn the key to "Start". The motor should start almost immidately.

As it warms up you may have to tap the primer a couple times. There's no need to advance the throttle because the motor has Quick Start and will advance the rpm's by itself until it's warmed up. Just don't shift it while it's in QS.

Re: 1991 johnson hard start

quick question, i havent gotten a manual yet, where is the primer solenoid located

pump the prime bulb tight.

Re: 1991 johnson hard start

The primer solenoid is located adjacent to your fuel pump. It allows fuel to be injected directly into the carburetors' throats when you push the key in. It will not do anything if you have not provided fuel pressure by pumping the primer bulb on the fuel line, however.

i pumped the bulb and pushed in the key, when i pushed in the key i could hear a click at the engine, i held it for eight seconds and tried to start it. it turns over great but didnt start

Re: 1991 johnson hard start

QuikStart should advance your timing whenever the engine is cooler than 96 degrees, and for 5 seconds whenever you start the engine. It cuts out after the engine reaches 96 degrees or 1100 RPM, whichever comes first.

If it does not work, cold starts are much harder. If your troubleshooting indicates that the QuikStart fuction is not working, replace the powerpack.

If you raise the warm up lever on the control too much initially so that the engine reaches 1100 RPM before it warms up, the engine may die, or at the least run quite roughly until it does warm up.

there is a red lever with what appears to be the eqivalent of bicycle valve, when ever i push in the key choke, gas shoots out of it, should it be pushed all the way to one side or the other.

Re: 1991 johnson hard start

Edit: When you push the key in, the fuel is supposed to be going into small hoses going to the top of each of your carburetors.

The pump is working properly. From your descriptiiom, apparently the hoses are not connected.

You should find the hose routing diagram in the next to the last page of your factory service manual.

thanks, i did see one hose that leaked when i primed the bulb, and on the red lever there is a crack on it where the gas comes out at. if i tighted the hose and replace the cracked lever do you think it might improve. i also held the key in while starting it and it started up.

Re: 1991 johnson hard start

im sure performace will improve if the gas is actually going into the motor! It does no good spraying and leaking into the inside of the motor hood! this is actually bad and can cause a fire and then you will be asking how to salvage your burned up motor if at all possible!

what are the correct spark plugs for this engine

captain what exactly is quick start.

Same goes for a '91 70HP? I have a hell of a time getting it started in the morning but like Jessiesmall, once it's going, it runs very nice.

Re: 1991 johnson hard start

Perhaps a detailed explanation and test procedure for quickstart in the FAQ section is in order. I took a look and did not see quickstart addressed in that section. Did I miss something?

Re: 1991 johnson hard start

hi all i was going to post the same type of issue my jonny 90hp 1987 runs all day but is a real bugger to start, i dont fully understand what pushing the ignition key does, and how long i push it for???

thanks

When you pump the bulb, it fills the carb bowls with fuel with some pressure. When you push in the key, it "primes" the cylinders. It opens a valve which allows the fuel from the carb bowls to flow directly into the cylinders to aid starting. This function is instead of a choke. There is a little red lever on the engine itself that manually controls that primer valve if for some reason the key doesn't activate it (which you can hear - push in the key, that valve should click).

One thing about 2 strokes be they 5 hp or 250 hp, they tend to have starting quirks. In my experience, you kind of need to learn what works best for your engine, and stick to that routine. It might be a little different in terms of how long to hold the key in, etc.

My V6 requires a solid pumped up bulb, a good 8 full seconds of holding the key in before starting ... then it starts fine. If I don't hold it in for the full 8 seconds, say stop at 5 or 6, it makes it a bear to start. Once it's started and warmed up, it starts like a charm. If it cools down, I just do the entire procedure again - including making sure the bulb is pumped up hard.

One way it was explained to me (which may or may not be true, but it makes sense as a mental image anyway): The bigger the engine, the more time it takes to get the fuel to the cylinders to prime them.
