Does anyone know how to determine engine size w/o tearing the engine down? These were supposed to be 70cc, the engines are stamped 49 cm3. The place is telling me they are all stamped that /forums/images/graemlins/confused.gif, but based on serial number they can tell me if it is a 50 or 70cc engine - yeah right. I'd like to be able to determine for sure before I call them back today with the serial numbers.
BTW, thought I would post a quick update. Kids have been having fun with them. Both of them had bad fuel leaks - to the point you would fill it up, go out the next morning and the tank would be completely dry. Looks like most of it was just line problems, they had real thin almost plastic type lines. I was at Lowe's and picked up a about 3' of regular 1/4" fuel line and some decent clamps and it seems like we are OK now. Need to check it again. One starts easy runs real good fairly quick, the other one got pretty hard to start - bad enough that my wife ran the battery down trying to start it. I've been able to adjust the carb a little bit and get it so that it starts pretty good. Just a little cold natured, have to let it run with the choke out for about 30 seconds to a minute, but then runs fine. I don't know if I'll mess with it anymore or not - don't wanna go back to the hard starting.
