I just bought a '99 Mojave 250. It didn't run great, so I changed the plug and cleaned the carb. I rode it around and it seemed a little better. The next morning it started after a few kicks, idled for a little bit then stalled. Ever since I cannot get it to start! I tried cleaning the carb again, but no luck. It has spark and the carb is getting plenty of gas. How can you tell if the gas is getting to the engine? The plug doesn't seem too wet, but it's not dry either. Please help!

are you getting spark? Pull the plug and put it in the coil wire, Lay it against the exhaust and kick it over and see it it fires. If you have fire then you need gas. Pull the carb boot off and put some gas in there and then try it. If neither one works pull the cam cover off and check the timing.

If the coil was bad then it wouldn't spark, right? It does have spark and I've tried putting gas directly into it through the plug hole. I'll read up on valve adjustment and give that a try. Thanks guys.

By the way, not sure why I said it was a '99 because it's actually a '90. I wish it was a '99 and I probably wouldn't be having these troubles!! haha

No luck. The new coil definitely gave it better spark, but it still wouldn't even sputter. I pulled the plug and it's definitely getting gas. I don't get it. Should I start taking the engine apart? Maybe the top of the piston is fried?

That really sounds like a fuel issue

I would start at the fuel pick up in the tank and work your way to the carbs...fresh fuel???

Pull the fuel line off at the carbs, got a good steady flow of fuel???

when you say you cleaned the carbs, did you pull all the jets out and blow through them with compressed air??

the fuel flows everywhere just fine and yes i used compressed air. i also replaced some of the jets with a carb repair kit. the spark plug gets wet with gas, so i know it's getting fuel. i don't think it's flooding though either because it's not black wet
