360 start up problem

Take the top of the carb off, 8 screws I believe and maybe a little linkage clip removal. The floats will come out with the top. there are pins that keep the float attached to the needle seats, pull them and the floats will come off and the needles will drop out (do it over a towel or something so they dont bounce under your shop table or worse) the seats come out with a large screwdriver across the notches. Carterbrocks are EZ to clean and rebuild. They also like only about 4-5 psi of fuel pressure max. fuel may be shooting out of those ports because you got a stuck intake valve and you are pressurizing your intake. Pop a valve cover and look at all the valve tips. If you pull the rockers (5 bolts) they should all be inline with a straightedge +- .015 or so. If one is very low, its stuck. Shoot some penetrating oil in the guide and tap it with a brass mallet, you might be able to free it up. Those ports are intake vacuum under the step up pistons and the needles go down into the jets in the floor. No fuel should be that high or shooting from there. The needle seats are the problem 99% of the time.
