Correct crank for 20" starjet deluxe?

[JesseA421]

Putting this together today, I'm not sure if this crank is even for a 20", as the leg length is like an inch shorter than another bike I measured. The chain guard is in the right spot but I'd have to grind 3/4 of the way into this crank to get it to clear the chain guard. Does anyone maybe have one that would clear cleanly? I attached some pics for reference, ignore Schwinn chainring I put that on there.

Maybe try adjusting the chain guard? Looks like the original cranks rubbed there too.

Are there bearings in the cranks? Chain ring looks tight to the frame. Spacer for the cranks might work.

I agree with Chad. The bracket doesn't look like it allows for much adjustment of the guard, so a big washer behind the chain wheel may be the answer.

Check to be sure there are enough extra threads on the opposite side for the lock ring and nut to compensate for the washers. Then, if the chain line to the rear cog isn't as straight as it should be, the cog can be flipped if it's concave to get some adjustment, or the chain wheel can be flipped if the adjustment is needed the other direction.

Do you have a pic of the whole bike ?
Looks interesting.

Sure.
