i had similar dramas

load her up with fuel and take the fuel line off before it enters the carby. crank motor and if it sprays fuel you know its not likely the fuel pump. I'd then switch car off and pull accel cable to see if you get a nice even and strong spray of fuel into the carby each time you pull cable. change the filters for the hell of it even though this is not likely the problem. when you get it going revv the shit out of it for a while to help clear lines/carby etc. if daring you could try revving it up and then choking carby with hand and rag. this may helps clear carby if its blocked? anyways there are much more knowledgeable fellas on the site that will no doubt get you back on the road! good luck and welcome to the site
