Engine will start but won't stay on?

I have a small engine, a honda 9.0 gx270, that starts fine, (used for a go kart) and stalls a moment later. I need to know how to fix it, but not sure of the cause. Could it be flooding? I thought a flood made it hard to crank. But it starts right up. Its not the spark plugs, i replace them weekly (i work in a go karting establishment.) it has a fresh air filter. I'm stumped honestly. Any suggestions or recommendations as to what it is and how to fix?

What are factors that could be preventing my car from not achieving top speed?

The car is a 2003 Honda Element 4 speed auto awd with almost 140,000 miles. I have a check engine light and it turns out be that I have a faulty upstream 02 sensor. Anyways onto another topic, When I was on the highway doing a short top speed test to see what my truck could do, it would get up to 90 mph but once it hits that speed it SLOWLY climbs up the speedometer until 95-100 mph then it wouldn't go faster? M. The brick shaped truck is pretty stable at 100 mph but I'm sure that it could go past 100 mph because after that the engine keeps redlining but it doesn't get anywhere. What could it be?

What does a fuel induction do for my car?

Will it help resolve the problem of a clogged fuel filter and top speed? When I was on the highway doing a short top speed test to see what my truck could do, it would get up to 90 mph but once it hits that speed it SLOWLY climbs up the speedometer until 95-100 mph then it wouldn't go faster? M. The brick shaped truck is pretty stable at 100 mph but I'm sure that it could go past 100 mph because after that the engine keeps redlining but it doesn't get anywhere. What could it be? What does this induction do for my car? A mechanic recommended that I get this service done on my car with almost 140,000 miles. I've never done this one my car. It's a 2903 Honda Element awd auto.

How fast is the 2016 sprinter 2.0t compared to my car? Can it keep up with me?

My car is a 2003
Honda Element awd 4 speed auto. So one my co workers who happens to have his dad stop by at work pulled up in a 2016 sprinter. And long sorry short, my co worker and his dad took my for a ride in this commercial van that they own and I was pretty surprised by how fast imit was able to quickly accelerate up to speed. For a high roof commercial sized van, it weighs about 8000 lbs but it gets off the line from 0-60 maybe around 9 sec or so and on the highway, going for a 10 mile test drive, it handled highway curves pretty well cruising around 75-80 mph. Unfortunately the van wasn't governed at 82 mph. Which is understandable but my question is, if this van did not have a limiter, could it possibly keep up with other normal 4 cylinder cars on the highway such as my Honda Element? Or would my Honda be able to outrun something like this? Say I was chased by an angry driver in this van, how fast would my Honda need to go in order to keep a safe distance between it?

Will replacing my spark plugs and a fuel induction system restore my vechiels OEM performance specs?

My car is a 2003 Honda Element awd 4 speed auto. So far it has been very reliable and practical for me in every aspect I could think of. However compared to the 2006 Mazda 3 i 5 speed, once it gets up to 90 mph, the honda struggled to go past that speed considering it's got more horsepower/torque than my Mazda did. The Mazda is no sports car either but that car i has no problems hitting the 110-115 mph limiter.

My Honda however needs to have the plugs replaced as well as a fuel induction service done.
Will my truck be able to easily go past 90 mph once I fix these problems? Could my Honda do 110 or 115 mph perhaps? I mean I have a Check Engel. Light on due to a bad 02 sensor plugs the spark plugs and a needed fuel induction service.

Can my car keep up with a Mazda 3? Explain?

My car is a 2003 Honda Element. It's a 4 speed auto with awd.

The Mazda is a 2006 Mazda 3 i with the 5 speed manual.

By looking the performance specs, the Honda makes 160 hp and the Mazda makes 145 hp.

Also the curb weight between these two cars are 3526 lb(Honda) and 2718 lbs(mazda3)

My question is, on a open highway such as an autobahn with some curves, can the Honda Element keep up with the Mazda 3 if the challenge was the keep up with it?

Will I harm my car if I install a k&n filter?

I have a 2003 Honda Element 4 speed auto Awd. From the research of this filter, it claims to have more air flow and less restriction, therefore it is suppose to give better gas mileage and throttle response. However, if that's the case wouldn't that means it's actually capturing kore dust particles in compensating for better air flow. It other words, destroy your engine?

This claims don't seem to make sense to me.
How is that possible that it's better than OEM? Would their be a trade off for something else?
