1978 CT90 round bowl carb
Hey guys,
Just got my bike back from the shop (conveniently right as I have time to work on it since they dragged their feet doing it since September).
Carb was fully redone, it's the original from 1978. New plate and points. Timing set, allegedly, haven't checked if they did. New spark plug boot and plug. Still drains batteries overnight, will chase that issue later.
All my batteries have been eaten by this thing. Lucky I work for a dealership, they cost me less than $10. I got a battery up to the level of "enough" to at least ignite fuel a bit. I know these things need a fully charged battery to actually run, but I'm just working out issues until my battery gets here on Monday.
Here's the scoop though, when I try to start it obviously it won't go because of the battery situation, but if I have the throttle open while kicking it will backfire through the carb.
I know you're not supposed to kick with the throttle open, but it's just something I do as a last ditch effort if it won't work closed.
I've read this could be indicative of an air leak, timing gear being off a tooth, or timing installed backward. But the fact that it only happens with the throttle open makes me suspicious if any of that is the case or that the backfiring may be normal. Before I go undoing what I paid someone to do (timing), I'd like the expert opinion of you folks.
This is my first post and first project bike, but I lurk here a lot, I promise I'll be back to let you know if your advice works.
