Need Scrambler 50 help
 

I picked up this quad for my kids, but I am having trouble getting it running. The guy I bought it from said it ran fine before he stored it about a year ago. I started by changing the fluids, plug and cleaning the carb out. I changed the fuel filter and air filter element as well as cleaned out the fuel valve. I also flushed and cleaned the tank out. The problem is it starts up fine and idels good, but doesn't run long. It will run for a few minuets then acts like it runs out of gas then won't start. If you let it sit for a few minuets it starts right back up and the process starts all over again. Anybody have any thoughts? To me it acts like a fuel delivery problem, but I can't figure it out. Any help would be appriceated.

Take the carb off again.. Make sure it is still celan, break it down completely, something might have still been in the line or tank. Sounds like something is blocking gas flow.. Also make sure your float is level as well. Take the bowl off and turn it up side down, check for level.
Good Luck

Of course clean the float bowl good . Make sure to remove the brass jet that requires the small flat blade screw driver. Pilot or slow speed jet.
Light should be seen thru the orfice hole or make sure carb clean sprays completely thru the jet.
Servicng the air filter is important also. Oil the foam piece. and squeeze out the excess oil on to a clean rag.

I went through the carb again and rechecked all the fuel lines. I also rejetted the carb from a 75 main to a 67.5. The quad runs 100% better than it did in the begining. I think it was jetted way too rich for our altitude, we live at 4500'. I ran out of time this evening, but will tinker with it again tomarrow. I picked up some other jets and now have them is sizes 65, 67.5, 70 and 75. Which jet would you reccomend at my altitude, and what setting on the needle do you suggest??? Like I said it is running much better, but I still have a little work to do. Thanks.
