Hey all....need help with a stromberg setup.I think my FE is seriously undercarbed,its running a single stromberg and im having some problems.I live in a fairly hilly area and am having some real dramas in getting up and going so to speak.The engine is a fresh 138,bored 30 thou and has a mild cam,and im running a standard 3 speed.When the motor is still cold,im getting a lot of blowback through the carb.Once warm,its a lot better,but i still think i should be getting better performance.The engine has great compression and im getting excellent oil pressure,and it makes all the right noises.I have a 2 inch exhaust with extractors,ignition seems strong and everything is timed as it should be.So what gives???...Im hoping one of you legends can give me some advice!                                                                               Thanking you in advance.....jimmys57

Double check that your distributor isnt one tooth out ,It could cause these symptoms if its retarded too much.
Also have you run your cam in properly ,If lobes have warn down it can also backfire out of the carbie.
