Hello friends, I hope you can help me. What happens is that I have an alzavidrio engine that does not want to work, it is only when applying manual movement, it works for a while and it is stopped again as if it is stuck or locked that it is difficult to operate. It is a Chinese model and is visually in good condition to disassemble and check everything looks good but does not want to work. What can I do to repair it or what method should I follow to solve the problem? [Img] Boris.
