2006 Suzuki Quadsport LT-Z250 ATV Carb Issue

[abobeau]

I'm trying to fix my atv that had been sitting for awhile and wouldn't start. First I drained and cleaned the fuel tank and pitcock and checked for good fuel flow. Next I pulled the carb. apart and cleaned all jets and passages. The unit will start and idle fine but will not rev up unless I partialy block the throat of the carb. Please help I've run out of ideas.

The air fuel.mixture might need to be richened up.

So far I have only found 1 adj screw that seems to only effect the low speed circuit. Is there another adjustment i may be overlooking.

Give Cheriah a PM she is excellent with carbs! Also see if Oxidized Black has a shop manual for your bike. Yeah tonight is name dropping!

Make sure you have the air filter on when checking your carb. That is why you have to block the carb intake because with the air filter on it is going to change the amount of air it will take in. try that before you do any more adjustments .

To My Quad Repair. Yeah I've already tried it with the air filter and air filter box cover back on.
