I have a H35 (sears craftsman side popper) Tecumseh that won't start when its Hot. Whats up with that? When its cold, starts on first or second pull. Runs like a top. Pretty fast and pulls well. I guess its a snow blower engine. Not sure of the year but it looks like it has points. 143-614042 serial# 1166P. I don't see a choke.ut: Any help would be appreciated. Thanks
