obe I would call a dealer and speak to one of their tech's for a solid
answer to your question.I use Abnerathys in Union City,TN. and am
impressed with their help and customer service!From other friends
who have made the same trip you are going on they had to rejet to
get the service they needed from the machine,two of them have traded
for fuel injected models since they have returned so hope that answers
your question.What part of MO.are you from,take care!
