help with a h.f. clone and large carb.
i have a h.f. 6.5 clone engine on homemade longtail, recently i decided to upgrade the carb and wiil eventully change the exhaust as well. i took the stock honda gx160/200 carb and replaced it with gx390 (aka 13 hp) carb kit from affordable go karts. it went on and together smoothly, however sprung a leak from a vent. i did some research and saw the sugesstion to clean the needle valve, jet, bowl etc. did that this morning spraying it with carb cleaner and a clean cloth it looked clean. it still has a small leak from the vent tube. the float was in good shape and had no holes. would i need a regulator to back the pressure down?
i love the power increase i'm hearing and want to get it in the water again soon.
forgot to mention it has a remote tank with a pulse type fuel pump.
