tried starting up the fg baja today bt for some reason the primer bulb would not fill up with fuel, ive pressed it a good 40 times- pulled the pull start a few time but still no luck. anyone know what the problem could be
 
How long since you last run it & have you had the carb off or fuel lines off? Check the clunk is in the bottom of the tank as it may have lodged itself up out of the fuel - has been known before. As above also check for pinched lines and flow & return lines on the carb the right way.
 
i had the same prob with my marder.
i hadn't started it for 4 months and it worked fine last time.
but i just couldnt get it to pull fuel through.
so i just took the carb off all the pipes off and just squeezed the bulb a couple of times.
put it back in the fuel pot and it worked great.
worth a shot.

How olds the fuel primer, Fuel lines? maybe its time to replace these ! Also carbie or fuel tank vent could be blocked!
 
Thanks for the info fellas, ive managed to fix the problem. i think i had air stuck in the engine as the spark plug was rock solid to take off soon as i got that off cleaned it up then put it back in, pulled the pull start ones and it fired then i pressed the primer bulb and fuel came up then i new it was going to start so i took it outside, kicked it again and it started :)

halifx- your problem seems similar to mine i hadn't started mine for a good few month either.
 
no prime

check the bulb very carefully for little cracks. i have several pieces of stihl lawn equipment. bulbs kept cracking. finally now they are replacing with a new compound material to with stand the effects of ethanol. works great now

ive sorted the probem now, thanks
 
You might have an air leak in the fuel line or a clogged fuel filter inside the tank. Check the fuel lines carefully to make sure they aren’t cracked, loose, or hardened. Also, inspect the fuel filter to see if it’s blocked. If both look fine, the primer bulb itself could be faulty and may need to be replaced.
