Hey guys, new to Sammy's and new to the forum, so please bare with me.

I have an 86 Sammy that is stock. It is a ranch vehicle for our place here in Texas. Not looking to jack it up or do any crazy mods on it. My problem is, to cruise around in it or climb a hill, I have to keep it in 4wheel low. If it try to go up, even a simple hill, in 2 wheel drive, it will bog down and sputter and die. I have to drop it into 4wheel low, put it in 1st gear, and keep the RPM's up around 2500 to 3000. It won't even climb in 2nd low. Fuel delivery problem??? Any help or advice would be greatly appreciated!

Thanks, Carl

Does it bog down or cut out?  Usually I keep mine wrapped up around 4-6k to keep it in the power band.

It bogs down. Once I start up a hill, the more I mash on the pedal the more it wants to die. I have to take it out of gear, put it in 4 wheel low and then keep it in 1st gear and granny my up the hill. It runs fine in 2 wheel drive as long as I am on a flat surface but throw any kind od incline at it and it won't do it.

Thanks for the response.

I would check the fuel filter first, just because that is a common issue.  Other then that with the old carbed rigs the best I can suggest is checking all your vacuum lines, the Hitachi carbs are really sensitive to leaks.  And the standard tune-up if it hasn't been done in a few years.

Hopefully someone else with more experience can jump on and give you some ideas.
