Hiya,

When you are starting it up is it smoking to beat the band?  Was doing a bit of reading on issues similar to yours and I wonder if you have a needle and float sticking behind the efi, which could lead to an engine that is getting too much fuel and essentially flooding as you are trying to start it.

I am not familiar with the efi 2 stroke engines of that vintage and would assume there is a throttle advance you can do as well?  If so, it also makes me wonder if the idle timing might be off a touch.  I had a Johnson 50hp that would die on me at the dock and was hard starting.  Took a timing light to the first plug wire and found my timing was retarded quite a bit...made the adjustment and it popped to life both cold and hot...

Not smoking at all and runs great once it gets some throttle.  Former owner had an issue identified with the TPS....I'm guessing it may be a revisit of that issue.  Will let you know what they say when I get it back from the shop.  Heading in on Tuesday.  Thanks again for all of the suggestions![/QUOTE]
