does the carb-cleaner damage the cylinder? /premix ratio

My wife has a 1981 Honda Express SR 2 stroke 49cc. Has the same type of probs as the Razz - runs good when cold then peters out as it warms up. Is hard to start when warm, and can only be started after several hard kicks with the throttle wide open. It actually runs better in the cold. I've cleaned out the carb (really well, twice), put in a new air filter and plug, it has a nice strong blue spark, and all the vacuum and fuel lines seem to be intact.
The varnish issue sounds like what's going on here, but I'm new to 2-strokes and was wondering if the carb cleaner would cause oil breakdown in the cylinder and lead to scoring. Can I just crack open the crankcase and clean it out while it's not running?
Second, does anyone know what the ideal premix fuel/oil ratio should be for this bike, stock everything except foam air filter, with the oil injector bypassed?
Thanks!
I am moving overseas and have a 1969 Honda CT90 K1b Trail 90 parts bike (approx 40% left, completely disassembled) that is free to a good home if picked up. There is not enough here to be put back together into a whole bike, just parts for one that you've got already. E-mail me directly at hayesp@uthscsa.edu if you need further info/parts list/description/pics on this. Also selling a 1975 Honda GL1000 cheap.
