Figure this out
I'm going to take full advantage of the general talk area. I want to give you guys a problem I ran into this week and see if you can figure it out. Call it a game, whatever. This happened on a car, but we'll pretend it's a Cub, just so it's less intimidating. Just because, let's say it's a Cyclops 2182 (3cyl Kubota, because then the engine is similar to a car). Hope at least someone plays.
Rules:
You can ask any question, and I'll tell you the answer that I found.
History:
~None. Brand new to the owner. Bought off individual, no questions asked. Discovered the problem after bringing it home. I figured out it had been on fire at one point, so electrical problems are a possibility. Also appeared that the engine had been apart somewhat recently. (Newer looking gasket on the timing cover, only one I could see easily.)
Problem:
~Won't idle. Seems to get worse the warmer the engine.
~Runs decent above idle, but lacks power/ weak acceleration. (Customer didn't realize it, but it did.)
~Misfire (Most noticeable at idle.)
Initial findings:
~Running rich
~Low vacuum at idle
~Confirmed ignition misfire.
What problem do you address first?
What's the first step?
