Hard starting 028

[wanna be]

Have an old 028, once running it runs great. It typically takes 15-20 pulls when cold to start, 1 pull when warm, I would have to assume it's gotta be a fuel thing? What's the most likely culprit?
Thanks

If it is running and runs great, I would make sure that the choke may not be closing all the way.Personally I suspect that you may have low compression. A compression test should be on your list.A lean carburetor setting could contribute to this anomaly.A stiff diaphragm in the carburetor may also be making a contribution to your starting difficulties, Ken
