Default Johnson outboards... hard to start!!!... any help??

It's long been a practice of many to run the carbs of 2 stroke OB's used infrequently dry before storing to avoid the feul in the carby bowl evaporating, and two cylce oil sludge left behind blocking jets next time out.

It does work, in that respect no doubt about it.

The downside?..

On ANY 2 cycle, the lubricating oil is in the fuel...and when you run those carbs dry - the fuel mix at first leans wayyyy out, this in effect makes the engine rev faster, AND hotter, all the while - the lubricating oils dissapeared! [img]/infopop/emoticons/icon_eek.gif[/img]

IMHO - it's NOT a good idea for engine longevity, to repeatedly keep doing this, IMHO.

Once in the long while if you KNOW your not going to use the boat in a long while I guess is less damaging than doing it as a matter of habit.

Cheers!

reel mccoy, I guess there is no harm to use the fast idle if the user doesn't over rev or flood the engine. To be honest, we have to ask, What is the fast idle for in the first place? I don't remember reading anywhere a recommendation to use fast idle.

My point is not that it can't be used, but that it should need to be used. My personal opinion is that if you need to use fast idle to start, then it may indicate that something is not quite right with the engine. Surely the normal choke should be sufficient for starting.

Trouty, now you tell me! I'll stay up all night worry about this now.

Point taken. Now why can't I hang my car engine on the back of my boat. It's certainly not this demanding. [img]/infopop/emoticons/icon_wink.gif[/img]

Bluefin... I may just be touchy on start up.... My 4 cyl Johnsons ALWAYS start, but I feel they need a bit too much"babying" to start on cooler mornings... Some guys at the ramps touch the key and bang!!! instant startup and smooth idle!!... I can certainly live with my engine ,and I may find it easier to start when I get some fresh gas in the tank...maybe I'll try putting some Stabil in the tank...... bob

Bluefin:

My starting technique with these carbed rigs has always been to squeeze the bulb tight; to pump the throttle several times; and to hold in the ignition key choke while I crank the engine with the throttle advanced just slightly forward. As soon as it turns over, I move the throttle immediately to slow idle, because even the smallest throttle opening will redline the engine while it's in neutral. You don't start a lawn mower with the throttle set at low idle: why would you do it with an outboard?

But starting these things is the major reason my next engine will be another Ficht. I had a '98 175, and it started just like a car: squeeze the bulb, depress the ignition choke, turn the key, and it would crank right over, as quickly, silently, and SMOKELESSLY as a four-stroke. Despite all the problems they've had (or are alleged to have had), those DFI engines are a great advance.

I also don't know many big outboards on which it is easy to run the carbs dry of fuel. On these things, the fuel line attachment to the engine typically has screw-on clamps rather than the snap fittings you find on smaller motors. But even if you could do it, I don't think it would be a good idea on a two-stroke. As Trouty points out, the lubricant in these rigs is in the gas, and there is no oil pan for gas to drain into and break down the oil you find on a four stroke.

Anyway, IMHO


BulletBob:

One reason some guys look so good starting their engines on the ramp is that they first try them out at home, hooked up to a hose. I always did that when I had a trailer boat: pull it out of the garage, hook up a hose and earmuffs, and test the engine right in the driveway to make sure the trip to the ramp would not be a waste of time. This takes two minutes. Then, when you do drop it in the water, you are not starting it cold. This eliminates the mystery and you can get right out on the water, leaving everybody impressed with your engine and your skills as a choke and throttlemeister.

BulletBob,

My 2K Johnson [img]/infopop/emoticons/icon_wink.gif[/img] has that automatic choke like LI Grunt mentioned. Just push the key in while cranking, no need to throttle. The only time you would need that, would be if it flooded. Then crank with the throttle wide open.

Guys.. I know about the push in choke..and I also know about the "start it at home" trick ... I do it all the time myself when the boat has been laying for a while... This "extended crank when cold starting" is not a huge problem... more of an annoyance really.... thanks again for all the help!!! .... bob .

I have also owned a few Johnson OB's and on the small ones (that is, pull start motors) the technique I have always used successfully when starting them cold is:

1. Squeeze primer bulb until hard
2. Throttle to recommended START position or a bit more
3. Choke out
4. Pull cord until the engine "pops" (usually a couple of pulls)
5. Choke in
6. Pull cord until it starts (usually a couple of pulls).

If they don't go after 5-6 pulls usually something is wrong. When warm, one pull (choke closed) almost always does it.

On my "big" motor (150) I have found that it needs lots of gas when starting cold... full choke, throttle cracked above neutral maximum. It always starts in a few seconds though.

Fountain Boy:

Buy a Merc or a Yammaha? I'd feel like less than a man without my big Johnson

reel mccoy,

Now I've heard people like yourself say they pump their throttle several times before starting. (By the way you do mean the throttle and not the fast idle lever?) Since the fuel pump is not running with the engine off, what does pumping the throttle actually do? I'll be more than happy to add another thing on my start up ritual list.
