Really tough cold start still after a year
My motor has been rebuilt for a year now and runs great when it finally starts. Once it starts, it's easy to fire back up throughout the day. I had a magneto in there up until yesterday, which I figured would be the reason it had a hard time starting. I'm having the same issue with the normal points and dual fire coil. Spark is hot, new plugs gapped to .030 and points is gapped to .020.
procedure:
- three prime kicks with throttle fully open
- gas on
- choke up, two squirts, kick through twice
- power on and kick
start over if it doesn't fire after a few
so far, I've only gotten action from the motor when I am bringing it back to Top center with the battery on. It just gives a light kickback on the kicker (maybe too advanced?).
timing is has been checked thoroughly. Tdc mark in window with both front intake and exhaust pushrods at their lowest point. Points set on the larger lobe just as they start to crack.
this thing is far from a first kick bike and starting to lose hope. I've checked the intake seals and they're seated properly (seemingly)

You didnt mention what bike or carb you have and as Joe said, every bike is different. My starting procedure with stock Linkert is
ignition off
choke closed all the way
throttle open all the way
3 or 4 prime kicks.
open choke one position closed from fully open
retard spark about a third.
throttle open about a quarter
get To TDC ignition on and kick her like you mean it.
When she fires, advance spark all the way and open choke all the way.
My bike actually starts easier cold than hot but she usually fires with one or two kicks.
As they say,your results may vary.
I hope you get it figured out. Its very frustrating and tiring to have an uncooperative kick only bike.
Good luck.

I follow same procedure as above from FL54. But what carb you have is important. Linkerts need the prime kicks as they have no accelerator pump. But if you are running something with an accelerator pump, you may not need the prime kicks. In fact with prime kicks and squirting the throttle you may be flooding her.
And of course the manifold leaking cannot be ruled out until tested. Leaking manifolds are usually the cause of bad starting. Good luck.
