Hi, Is there any way to put a longer shaft to this engine? I have searched but can not find a replacement shaft that is longer than the original. Attached schematic to see the problem, I think it goes too tight.
Reverse the motor pulley?
I would have to bring the wheel pulley closer to the motor mount, to re-align the pulley motor and I do not think I have room for that either.
Can you take a picture?
I have not yet begun to build anything, only on paper.
…I have no solutions for virtual problems…
The only solution I found is this, but it requires more mechanization, and I do not have many tools for this, I want to keep it simple.
Hey, it not a real problem if your sprocket miss a millimeter of shaft 
But your last propose could work but I will shoose brace with 0.5 or 1mm more longuer.
What do you mean, brace?
Sorry … “entretoise” in frensh … maybe spacer in english ?.. Better in picture :
The “spacer” between the wheel and the driver :
or like my upgrade :

You’re right, I do not see the threads on the plate, they are embedded?
yes 3 spokes and also I like that you could also add a bearing more !
