View Full Version : Running engine at extreme angles
The other day while I had the Wag up on a real steep hill (the rear bumper was on the ground and the front wheels were about 6 feet above the ground) I noticed that the exhaust was a little smoky…my exhaust is not normally smoky like that… :( Is there something bad about extreme angles? Does the oil leak into places it shouldn't be at? Is it possible for oil to leak right out the filler tube and back into the airfilter? Andmost importantly...am I ruining my engine?
If I picked my nose half as much as I picked your brains...I'd have one booger-free nose! :D

Was the smoke black (fuel) or bluish-white (oil)? If it's black, I would suspect it has something to do with the float allowing excess fuel into your carb.
Well, there wasn't really a whole lot of it to tell...I could barely see it...my carb is a peice of poo...would a rebuild help (sposing that the carb is the problem?)
BTW...that carb may be poo, but it has never let me down at crazy angles...that thing just keeps on going! I love it for that.... :D

dont touch the carb!!!!!!!!! not under any circumstances if it runs great now dont touch it it'll never be the same

Now what the heck is that s'posed to mean? It runs great at angles, but it won't run for dog poo when cold in the mornings (I am rueing (sp?) the day that the cold weather returns and my 401 is reduced to a sputtering poo-pile that can't pull out in traffic till there is a mile-long break to get up to speed in.)
So IMO the carb gots to get touched...hmmmmm....everyone always says the carb rebuilds are easy....what is the discrepancy here? I was confident about a rebuild until you posted this, midnight...did you get burnt or something? Let's hear about it...mebbe I can learn from your mistakes...but prolly not :rolleyes:

Could have been sucking oil into the PCV valve.
Jode, is your choke manual or electric? That could be part of the problem with cold days... I hate electric choke..
as far as smoke coming out when you're running angles... that's how you know when you're starting to have fun. Fun isn't usually good on a motor though.
Dunno bout the choke...I'm retarded as far as carbs/chokes, etc...never gotten into one...and that's the only way I knwo anything bout Jeeps....jumpin in and doing it...maybe you'd like to set a side a day to come over and learn me a thing or two :D

JOde sounds like your carb was loading up. Mine does that sometimes a steep nose up angles whill rock crawling.
Jode, I was hoping you were the knowledgeable one... hehe
I think mine is electric cause there sure isn't any means of choking the thing manually, and just by looking at it I presume that the choke keeps the little butterfly thingy open till the motor heats up, allowing more air into the mixture?? Once the motor is warmed up, the choke closes and everything is good... but that's just my guess. I really don't know what I'm doing, or what I'm talking about.

Tuck:
You have it a bit backwards. The choke plate closes when it is cold to richen the mixture for a cold start. As the vehicle warms up the choke open to allow free flow and normal mixture.
I had the same problem loading up on extreme angles. Nature of the beast for a carb. You can try setting your float level a little lower but in reality the best bet in the long run is to go to a fuel injection setup.
TPIGUY can help you out with sugestions there but it has made all the difference in the world in the CAMO COW. Better fuel mileage, throttle response, no more loading up and dying on steep or off camber grades.
Try going down a steep grade and the motor dies. You'll be glad for every ounce of strength in your lags as you try to stop the beast.
OK Gary, so it is loading up and it is an inherent problem with the carb...
...but is it bad for the engine? Is that jsut a little unburnt carbon coming out in the form of exhaust smoke...

Carb rebuilds are easy. It is normal to load up on extreme angles. Check your choke to make sure it is operating normally in cold weather, ie pull the cleaner off before starting and take a peak after you get it running. I would switch to manual. It's easy and you always know if it is working. No it doesn't hurt the engine to run rich. Just puts more carbon on everything. Better rich than lean.
Carb rebuilds are easy.
OK so why is Midnight Wagon scaring me with the whole "touch the carb and it'll never run right again" thing?

Hmmm...Ive tryed that and can't seem to note any difference...I guess that means my choke ain't working huh?

I think I would adjust the choke for the cold starts and if it stays running at really steep angles and is only blowing some black smoke I don't know if I would mess with it either unless it is truely in need of a rebuild. I think midnight is cautioning about rebuilding a carb that doesn't need it and having it not run as good as it does not on angles (which is a common problem). You may end up having to mess with the floats and tune many times to get it to run that good again at angles but then again maybe it will run better. When it comes to running at steep angles if your not killing the engine I would probably not mess with it.
But you know what they say about opinions...

Hmm...good advice...the other problem it has is that if I dump on the gas hard, it will kind of stumble and hesitate before getting going...almost kills it...I'd like to be able to get it to where I can hit that gas and GO!
Will a rebuild help with that?

Its kind of like when a train departs, real slow at first and can make some good speed over time and then it has a hell of a time slowing back down.... Good luck
Well...mine actually goes pretty good off the line with the rebuilt 401, but if I hit the gas past a certain point...that is where it kills it...that's why I thought it was a carb thing...
