Need help!!! 1997 Suzuki King Quad No Start

[Youthgonewild]

I have a 97 Suzuki kingquad an a new carb an yet still flooding an sounds like it wants to start but won't. Flooding so much that while cranking over gas is actually spraying out the back of the carb.  I'm thinking maybe need new fuel pump an check my vaulves an timing. Also don't know how many p.s.i. the fuel pump is an can I switch over to an electric on????

If that's a new carb, it shouldn't be doing that. Sounds like a carb float or jet issue. Electric fuel pumps are for fuel injection, you should have a mechanical fuel pump. Gas spraying out the carb sounds like its under pressure. 

If you have a 300, here's a good video illustrating a mechanical fuel pump and delivery.

I ordered a new fuel pump will be n in few days. Will follow up if changes things

It is possible that the fuel pump is at fault but not that likely. They only make a couple PSI which assists in bringing gas uphill to the carb when the fuel is low in the tank. When they fail it usually results in a lack of fuel, not too much.

What I suggest you try is a simple test: remove the original fuel line at the carb & get a clear hose of the same size. Connect the hose to the carb and fill it with gas. You need to support it vertically and watch the level in that clear hose.

If it drops and cannot hold that level, the problem is with the carb - float valve or float itself is bad. Sometimes it takes quite a while for the level to drop but be patient, I've seen many carbs fail this test! Worth a try and it's cheap!!

Spock58 is correct. Pulse fuel pumps aren't capable of producing too mush pressure. You most likely have some debris between the float needle and seat is the carb. or the float needle is out of place, or the float or needle are sticking or stuck for some reason. A quick inspection  and cleaning will probably solve the problem. You can retest it like Spock58 says before reinstalling it as well to see if you have the problem resolved. make sure the float bowl gets completely full and fuel and the tube is staying full also. A small auxillary fuel tank might be helpful here as well.

Check the vacuum hoses going to the fuel tap and the fuel pump, they might be sucking fuel down them and into the engine. They could also be leaking all the time and fill your sump with fuel. Check the oil level and smell looking for fuel.

Is the replacement carb oem? Or china brand? That might be what's wrong.
