My 48 SA has a carter carb. When I try to start it I need to choke it and then if it catches I need to quickly un-choke it and hope it runs. I need to use 12V for this to get it cranking good and fast too. If after a few turns it doesn"t start and I stop cranking a lot of gas seems to pour out of the carb. When I pull the plugs they are bone dry so it looks like no fuel is getting up there. The float seems OK and once it is running it seems OK and doesn"t leak. What causes this? I am sure this is what is leading to my hard start problem. I tried spaying starting fluid in the carb and had no luck.
I got a rebuild kit from TSC but it really didn"t have that much in it.
I found a used Zenith carb for sale at a tractor salvage yard - is the choke and governor linkage in the same place as the Carter setup? How about the fuel line hookup? Not sure if it is a direct swap or not.
Once it starts it idles and runs decent besides smoking a lot which appears to be oil since the smoke has a blueish color to it.
Could my valves be out of whack? Maybe a small air leak somewhere? After it has been running for a while and I pull the plugs they are all carboned up, which is most likely from the oil burning problem. I have great spark still though.
