Re: CJ - 360 \"loads up\" at idle
The 2150 is notorius for 2 things, leaks at the base plate, and leaks around the throttle rod where it passes through the base of the carb. Both are easier to replace the carb than repair. To check this start the Jeep and remove the air cleaner, plug any vacuume lines,(if applicable) Spray around the base of the carb with carb cleaner, (don't get any in the top) if the rpms pick up then you have a vacuume leak around the base or throttle rod. Sometimes a loose gasket or deteriorated base gasket will contribute to this. But in most cases it is a warped base plate on the carb. Also spray around the intake where it bolts to the heads to check for leaks there.
