[QUOTE="JL8Jeff, post: 397189, member: 12995"] It could be related the enrichment valve if it adds too much fuel. My 1994 60/45 Mercury smokes a little bit when you first start it or restart it so that's somewhat normal. If you're getting a lot of smoke then I would lean towards the oil injection not working right. Mine was bad and the motor would barely run and it leaked so I removed it and I run premix synthetic around 80:1 and still get that smoke at start up. I pulled the injection pump off the motor and removed the drive gear inside and then put the pump housing back in place to keep things sealed up. I have the gear and shaft stored with my other motor parts if anyone ever wanted to put it back on. I also capped off the oil hose and my reservoir is empty. I've been premixing for 25 years so it's no big deal to me. [/QUOTE]
