Hey everybody! <br /><br />I just got back from the launch testing my 1958 Johnson 10hp Model QD-19 and it ran GREAT! The engine fired right up and never reverted back to my origional problem of one cyl. quitting. I set the low and high speed screws to ear and ran it up to WOT, no sweat! This should work 'till I get my tach in the mail. <br /><br />Thanks for all your help with this project! Now it won't take me 15 min to cover 1.5 miles this summer(1968 chrysler 6HP). Even though I have no more problems or questions, I am still going to check posts and reply if my limited knowledge will serve someone well. Hope your summers are filled with fun and fish!<br /><br />Kevin
