David Marshall Posted December 3, 2020 Share Posted December 3, 2020 Good afternoon everyone, I have my Buick semi sorted. BUT has anyone had experience running without the heating of the carb off the manifold ? The pipes that go from the manifold to the carburetor to warm up the fuel are beyond help. I was told to just take them off. The mechanic that has helped me said it will run a bit rough until the carburetor/engine gets warmed up. Also every time we put the choke back on the carburetor it started to flood. The car starts and runs really well without the choke ? Any thoughts or advise would be so much appreciated Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted December 3, 2020 Share Posted December 3, 2020 David, The fuel heater system is no longer necessary with today's fuels. I have never run my 1925 Buick with the heater system. I blocked mine off during the process of rebuilding the engine. All engines need to "warm up" and they all will stumble a little until they do. Not so much with modern engine management, but certainly anything with a basic carburetor and points ignition. The only time I ever use my choke is pulled out full for a cold start. Once the engine starts, it is off. Running a choke for me means fouled plugs in my old cars. If I do ever use the choke, it is barely on, and not for very long.

David Marshall Posted December 3, 2020 Author Share Posted December 3, 2020 Thank you Hugh, you have been a great source of knowledge and advice. I really do appreciate it. We don’t have winters in NZ that you guys would think cold. In fact we live 5km from a beach and it’s a warm climate 95% of the time. If it’s too cold I wouldn’t take her out. Thank you again, Dave Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted December 3, 2020 Share Posted December 3, 2020 David, Glad to help. Funny that you mention NZ, but I may be closer to your climate than you think. I live near Houston Texas, and I am 15 miles from the gulf coast. We rarely see freezing weather here, but it can get cold in the winter months and evenings Hugh.

Rod Wise Posted December 3, 2020 Share Posted December 3, 2020 (edited) David. I agree with Hugh. You don,t need the heat connected. I have bloked off the heat at the manifold and the exhaust on my cars. On my 1920, I give it half choke to start, as soon as it fires close the choke off. I never thought of NZ having a warm climate, 37C / 98F here in Aust, the other day and only the first day of summer.
