I bought a Samurai from a police auction without any ownership papers so i'm depending on the 17 digit VIN for the year. The 10th. digit is an H which indicates it's a 1987. I'm quite sure it has a 1.3 liter-1300cc engine and it doesn't have an O2 sensor. It has a 5 speed trans. The problem is with the carb. Somebody took the factory air cleaner off and replaced it with a snorkel. When they made this swap they chopped some plumbing and some wiring but it worked really good according to some of the local off-roaders. It sat for 2 months and when i started it it wouldn't idle below 1800-2000 and it went through 2 gallons of gas in less than a half hour without turning a wheel. I cleaned up the outside with a spray can of linkage cleaner and ran a can of cleaner through the throat. That helped a little, i got the idle down to 1500 but still pretty rough and no change in gas consumption. The distributor timing is set at 6* before TDC. Got any ideas? Wayne
