I have an 86 argo with a 18hp kohler engine that seems real tired. Have had it in the shop 3 times but it still is hard starting when cold. Seems like the engine is just worn out and would like to put a new engine in. Could anyone tell me what engine I could replace it with? Looking for something to drop right in with out alot of changing around. Any help or direction would be appreciated. A lot of info on this site but need to narrow what I need to do.
Thanks
