Running Rough

**rancher3!** · 10-28-2009, 12:38 PM

My '90 Mits mini has been running rough all summer, the common problem of running rich. Checked choke linkage, tried Sea Foam, still no results. Now when it is cold it starts decent and runs good until it warms up, then it stalls and is hard to restart. Any help would be great.

I am guessing carb problems, choke not coming off when warmed up, vaccumm line leaks? Rotor, cap? Carb needs to be rebuilt?

Mine starts funny sometimes also I am thinking carb needs a rebuild, I might try plug wires first, have just about replaced all the vaccuum lines.

I thought that the choke was pulled off by the coolant temp going up. Is the linkage operated by vacume

I am unsure guessing so.

Start it up cold with the aircleaner off in a fairly dust free place. You may need a mirrior and a light to see the choke go from closed to open. Unsure about the mitzis.

There are quite of things wrong with this version of vb. I've already ordered the newest vbulletin version 4 and when its release, we will be upgrading.

As far as the uploading option, you could use www.imagelinky.com then post the forum link that it gives you.

I've tested the upload option with many browsers and have no issues.

Well here goes i hope it works! Really enjoy the forum and the mini truck but it sure is frustrating when it won't run.

Nice truck...do you use those tires on the street ? how much bump steer are you getting with them,if any

**rancher3!** · 10-30-2009, 03:36 PM

The truck is used off-road only. It will see gravel roads and the handling is not quite what it was with the 12's but is not that bad.

That is a Good looking truck. I like the ROPS over the cab, been contemplating one for mine. Just got to figure out how to tie it back into the frame so as not to interfere with the dump bed and stick out too far on the sides.

By the way, how did you get all that Florida beach sand in your yard way up there in SK? -------Wait a minute, I bet that's probably that "cold stuff"

Hope you get your truck running......later, slim

go to your local auto junk yard buy a 2 wire coil and give it a try. (you can use one off all cars and trucks that is a 2 wire)

**slimbad** · 11-04-2009, 04:46 AM

I agree with Starpuss, it does sound like you have a weak/failing coil. Here's a link to a similar prob that Starpuss recommended a coil fix that worked:

I read the link, describes my truck to a T, last night i took it out and worked it real hard, moving cows through creeks, bogs and hills. It worked the best it has for a long time after it was warmed right up. Will try coil this weekend hope it works! Thanks for all the help.
