- You could have a choke that is stuck open, or you could have some sort of
- problem with losing the gas that was in the carb bowl, and have to crank to
- refill it.
-
- The choke operation is easy to verify. Park it hot, let it cool. Take off
- the air cleaner and look at the choke plate. Should be straight vertical.
- Now open the throttle slightly (use the throttle linkage). The choke plate
- should snap shut, or partially so. If it moves slowly, it needs cleaning.
- If it doesn't move, its linkage may have come disconnected or the housing
- (for water or electrical chokes) may have rotated, it may be nicely gummed
- open, etc.
-
- Some carbs develop gasket leaks which allow the gas in the bowl to drain into
- the intake; then you end up with an empty carb (causing a cold starting
- problem) and possibly hot starting troubles as well, if it sits for just
- enough time to drain, flooding the intake, but not enough to boil it all
- away.
-
- A dry carb can be checked by working the throttle linkage and observing
- the accelerator pump shot. If it squirts once or twice but not after that,
- or not at all, you may deduce that there is not much gas in the carb
- (assuming otherwise normal accelerator pump operation).
