Hey guys, just got a second mini bike today. I believe it’s an old Taco mini bike but please correct me if I’m wrong. It has a Tecumseh 5hp OHH50 engine which turns out to be quite different in design from my other mini with the Tecumseh 3.5 so I’m pretty confused at the moment. On the 5hp one there is no on/off switch of any kind and no choke on the carburetor. It has the primer bulb style carb so I guess those don’t come with chokes? I tried to choke it manually by taking off the air filter and plugging the hole with my thumb but still no luck in getting the engine started. Not sure if the other guy ever had it running with that engine but part of me thinks it needs some type of ignition on/off switch to run? He said he got it off a lawnmower so maybe they are slightly different in design? I think that because when I look up the owners manual for the OHH50, Tecumseh mentions multiple things about the on/off switch and the choke. Part of me thinks the carb could be dirty and need and clean but the engine looks so well-kept and wasn’t stored with gas in it so that’s kind of hard for me to believe. Hopefully you guys can give me some insight and advice, I’d like some more knowledge before I start digging into the carb and messing up gaskets and what not. Any help is greatly appreciated. Sorry for the long post.
