Hard Starting 1958

#1

Post by jtlittle47 » Wed Jun 03, 2009 5:36 pm

1958 Duo-Glide with original carb. Is there any starting setup on Liebert Carb to get motor to start. I can't seem to get gas back into cylinder to fire. I can spray starting fluid in through carb and it will fire everytime. If I choke engine I get too much gas and floods. I am rebuilding this engine and have everything done except getting started. I am trying not to have to buy a new carb. Please any help is appreciated. My legs (63) yrs old won't kick it too many times before I have to stop.
Thanks

From your description of whats happening I would bet you have yourself a sizable intake manifold leak. It is a very common problem and not to difficult to fix. Remove your carb and do a pressure test of your manifold with soapy water.

If you had a sizeable manifold leak, it would upset your idle speed. Did you have to make sudden idle speed adjustment changes? To test If a manifold leak were present, squirt a bit of gas over the nipples and connections while its idling. Notice any change in engine speed and smoothnes/roughness....Joe

I've seen a few folks use flammables such as gasoline or starting fluid to check their manifolds for leaks. Some of them get lucky and get away with it, and some have had to call the fire department. How lucky do you feel? :?:
