Seems like the ole Wing is weak on top end all of a sudden . You would never tell any thing was wrong until ya lean on it , then it just revs to around 4500 rpm's and thats all the farther it will go. No pop'n miss'n , cutt'n out thats just it. When you go into OD about 75mph is it . Runs perfect there , just not any faster . Any one run across this before. Thanks Runk ......
