Hey everyone, Hope all are having a good new year. This past week I took my truck out to tow my kids around my property in the snow and when I would come to a stop in four wheel drive or even two and give it gas to start up again it would bog down. Now I have heard a few of you all say that they dont like the cold weather so if that is the problem what do I do. This is the first problem I have ever had with the truck and want to fix it before it turns into something bigger. If you have the answer pls let me know what to do to solve the problem asap. Thanks Steve
I don't remember exactly where the air intake is for the Mits. (pretty bad since I owned one ) but if it is under the bumper like in the Daihatsu it could be packed with snow and choking the engine
Mine is a early 90's as well. If you are in snow and in 4wd you need to get the rpms up before you let the clutch out or it will kill it. It doesn't help I have lots of weight on the truck. lol
Probably just popped into the head when he mentioned the engine bogging. I wouldn't have known he had a carry either if he didn't post back. I always use the whats new tab nowadays so it's harder to notice the category things are posted in. I've noticed my truck has less power if it's cold. Maybe it would help to re jet it for the winter lol.
Years ago when I lived in Colorado I had a 1942 Jeep and the gear oil got so cold it would barely move.Reverse was the lowest gear ratio so a lot of times I would have to back for a block or 2 to get it to free up.I knew a couple of guys who drained the 90 wt and put in sae 30 non detergent oil in the winter.Just a thought.
Cold air is more dense. It's like driving below sea level @ 15 degree C. The opposite problem to running at high altitude. You're running too lean, as apposed to running too rich at high altitude. Most guys don't experience this problem as their carb leaks like a sive... Reads like your's is tight. You can either use a pre-heat, or an air flow restriction. Are your pre-heat tubes in good order? Anyway, the way to test for this is to make a wire that will hold the choke butterfly closed about 5 to 7 degrees. Do what you normally do to get her up to temp and all that, then put the wire on and take her for a drag race. If that is the problem, a carb adjustment can be made to the main choke controller; for winter ops... Try it out... PS, carb icing is possible, but rare on a ground vehicle. Not going to happen twice in one week, that's for sure. http://www.youtube.com/watch?v=F4PxWdOWAPY ...
Where I am at in Alaska carb icing is an ever present problem, that is why all sleds have extended bottom nuts on the cards or rubber hose. It is amasing what one little drop of water will do in one of the tiny jets in a carb. I did however take off my original card and put on a mikuni flatslide so I don't know if that little bit raidtor fluid in the original carb or the pre heated air make it better.
Sorry been gone a long time but my hijet was bogging as you describe and a tune up kit with fresh distributor cap and rotor, plug wires, etc. and it's running like a raped ape again. Tune up kit #2 $80 at http://www.grparts.net/category-s/256.htm Minimurph
