I've got an 87 Samurai, 157k miles on it. Everything under the hood is stock. Bought it back in September, didn't have too much trouble getting it started when its warm out, but when its cold, I have a hell of a time getting it started. This morning it was around 30, and I had to try to turn it over about 10 times. I gave up originally, then came back for 1 more try and it turned over then died, about 3 times later I had it going. It typically idles at about 1.5k rpm. Cold mornings it'll idle around 1.2-1.3k once I'm comfortable enough to take my foot off the gas. A minute or so later I'll finally release the clutch and let it warm up.

This past weekend I changed the oil and did some spray type carb cleaner, doesn't look like it helped much. I know I need a new warm air hose, but that shouldn't effect just getting it started in the morning, right? Any idea's for what I can do to get her going easier?

You should check that the autochoke is operating correctly.

The warm air hose wont effect the starting, only the function of the running when cold, and mostly the exhaust emissions.
It's probably the water choke element. They wear out over time and wont close the choke on cold mornings.
Proper choke operation is depress throttle all the way to the floor and release - choke plate closes fully, accellerator pump gives the intake a shot of fuel and high idle is set on the choke cam. Crank it over and as soon as it fires, the engine intake vacuum pulls the choke plate open slightly, allowing the engine to run. High idle stays set and gradually decreases, as the water choke warms up and pulls the choke plate open.
Both the water chokes that were on my Suzukis were shot (1 had a Weber on it). I was able to make one work, by bending and adjusting linkages, but its way off from what the FSM says the adjustments should be. I put a Weber on the other one.
A new water choke for an Hitachi carb runs about $400. :eek: no wonder you see a lot of Weber conversions.

Thanks for the replies guys. Great info there. I've got a guy helping me do some welding to cover some rust this weekend, then I have to relocate for work the next weekend. So it'll be a few weeks before I can take a look at it. Found some info on maintenance for the choke after reading y'alls replies, hopefully I'll be able to clean up the cold weather starting issues from there. Thanks!
