Cold starting at 2C - brrr

Then:



Now:

That white stuff is disgusting. I've been counting the days till spring since the end of August.

More throttle and more electric primer.

Well, as I had the throttle lever at MAX and ran the primer continuously thoughout the starting process, not sure how to do more without increasing the primer nozzle size or altering how high the fast idle can go.

Where do you do your cold weather boating?

Tell me about it. I've turned my mechanical attention to putting new rubber augers on my snowblower. Another 2-stroke machine which always needs to be started first time using the electric starter as it usually refuses when pull started.

When I had my 90 it was a cold blooded beast.I have the same initial issue with my 4 poke snowblower also.And the evil stuff is coming soon I fear.

 

[jakedaawg]

Yuk, no more pics of snow please....i have too many left to winterize and wrap.

My snowblower with Tecumseh 4 stroke usually starts first pull.----Full throttle , choke full on and about 4 pushes of the rubber primer bladder.----Nothing to it when you understand how it works.

I'll just ask again - without being able to increase the fast idle any farther, or have any more priming than can be afforded by the primer solenoid system, how would one improve cold starting sensei?

If you have low speed needles, set them richer, Make sure the float is set on the tolerance range that allows the highest fuel level, Drill little holes in the silencer to allow spraying fuel mix into carb throat. As I said earlier, I preferred the choke system, but you don't have that option. DO NOT succumb to 'Starting Fluid', that is a sure fire way to guarantee you doing another rebuild. Sounds like you wannabe prepared for the ice fishing trip.

my blower is only stubborn the first of the season and only once after that one pull all year,most likely crappy gas.have you tried gapping the plugs a little wider?because I trolled a ton with my 90 I did that and it seemd to have the added bonus of easier cold starting.standard gap was .030 and I went to .040.it wasn't something I dreamed up either it was an evinrude manual suggestion for heavy trolling.sorry I never read your build,is that really a 140 in hiding?

No needles to twiddle, and floats are set parallel. The carbs are '79 1-3/8" bodies that I drilled for the primer jets - took all the choke flappers off (destroyed most of the plate screws in the process of removal), so that's not an option.

From the sounds of it, my best method (should I ever need to repeat starting in low temperatures) would be to pop the hood, turn the primer to manual, pump the bulb a few times to cram some more go juice in, then start with max idle and constant primer actuation.

And no, no plans to use it for any ice fishing. For many reasons, not the least of which my fishing trips usually only go as far as my local fish shop.

I set the plugs at 30 thou per many tips here. Good tip about larger gaps for cold performance. For trolling, should I want to, I have my tiny 2hp Mate.

And yes, there are 140 ponies under that 90 bonnet.

 

[jimmbo]

, there are 140 ponies under that 90 bonnet.

One of the faster 90s on the lake I presume

Presumably. Maybe I'll drag it down to the salt next summer and see what she'll do there.

 

[jimmbo]

1100 meters lower and denser slippery salt water, she will haul. You will need a prop change. I didn't consider towing thru the Coquihalla fun in any way shape or form, but I guess its easier than Hells Gate. I would check about BCs laws regarding towing weight limits without trailer brakes, in Alberta there aren't too many restrictions, but its pretty flat.

Trailer has surge brakes (disc), so we're set there. But with only a 3.0 in the X5, long hills on the CocaCola will be a griiinnnddd. Used to be good for about 4mph difference on the salt.

Some steep grades between Hope and where the toll booths used to be.

I remember there used to be a Brake and Radiator shop just outside of Hope, I think he had a booming Business going. In 1986, the first time I drove the Coke, there were cars, trucks, and semis all along the shoulders, smoke just pouring off the brakes. Saw several of the Runaway lanes with tractor-trailers in them. Good news, the speed limit is 120, easy to attain heading for Hope

No need to remove the hood, just push the key in and squeeze the bulb, does the same thing.

Yeah, that one grind heading East out of Hope is brutal. We had a Mazda 5 (tall wagon) that had the transmission go into limp mode on a hot day with not a lot of load. It recovered after cooling off after the summit.

Were my arms 8 feet long, that would work.

 

[ondarvr]

Squeeze the bulb then push in the key, repeat this a couple of times and it's no different than taking the hood off, only much easier.
