Re: 1962 Johnson JW won’t run

Frank is right,the only way to really see what is going on there is to pull the exhaust cover off.Even with low compression you might want to check your lync/sync.Move the throttle level all the way to the stop position.Now look where it says slow;you will see two small dots.With the motor cowl off,move the throttle lever to the slow position.When the lever is between these two dots you should see the carb linkage just start to move and open.If it doen’t your timing is off.if the timing is good,then take out the high speed needle and see if the needle is grooved or badly blunted.If the needle looks good then screw it back in to a lightly seated position and turn it out 3/4ths of a turn.This is just a starting point,as I have just finished with a JW10 that will only start and run well with the needle turned out a quarter turn.Good lock
