Wheel feed issue - problem or design limitation?

Recommended Posts

I have a Pfaff 34 (thank you all for helping me set it up!) from the 60s with wheel feed. I've mostly got the tension figured out, but another issue I'm finding is it will just fail to feed properly. With thin vinyl it feeds fine, but I'm having issues with 2 oz nappa lambskin and 4-5 oz latigo (waxy chromexcel). Testing with 1 layer of the 4 oz or 2 layers of the 2 oz, it doesn't seem to feed consistently, it'll just stop at a certain point, whether I'm actually sewing or not.

My (uneducated) inclination is to say that the feed wheel is too low and the presser foot can't consistently keep it in contact. But I've never used a wheel feed machine before, so I don't know if it's supposed to be like this. It's a good mm or so beneath the level of the needle plate, which doesn't look right to me.

Edit: Or is the needle plate too thick? it's a good 1+ mm thicker than the cover plate next to it.
