That why many good saws end up in the parts bin or recycle centers. By the time we put parts in and add our time, end if it is a flat rate, there times it is simply more economical to simply replace it. It is like a handheld blower here I killed off last month. Parts were $25.00 and my labor is $40/hr (charging for one hour only) but a complete new unit is $69. Just not worth my time to taking 2-3 hours to short block it as it is a complete disassembly and rebuild.
I do rebuild the low end stuff for myself as newer equipment junkier than the older equipment but just can't justify it for my customers.
Just remember that Aldi one is probably a Chinese clone at that price considering currency exchange rate which make it around 71 usd.
But anyway glad you were able to get it running. I like older equipment.
