Question
cannot get fuel to engine. will run on a prime. fuel lines have no leaks. dose carb have somekind of diafram how does it maintane fuel press.?

Answer
The carb has two diaphrams.  One is the fuel pump and the other is the metering diaphram.  If you can prime fuel up to the carb and get it to start, you will need to remove and clean the carb and install new diaphrams.  It would also be a good preventative measure to replace the fuel filter as well.  Hope this helps.
