"Take the carb apart and clean

"Take the carb apart and clean it. IT is easy and well worth the time. Make sure all of the jets are clean. The best way I have found to get all the crap out is to disassemble it all the way removing all the jets and wash it out under pressure with water, then blow it out with an air compressor. Be careful not to lose any parts but this works very well. If this doesn't solve it then replace the fuel pump or bulb. Also you may want to look for leaks at any of the connections or at the bulb."

I havent had the cash to buy a new fuel pump yet but will soon. If that doesnt fix the problem then I will clean out the carb. If that dont work I will have to figure something out
