1960, johnson, 40hp, runs great until warm then misses only on WOT.<br /><br />Experts, any ideas?<br /><br />I have tried high speed needle adjust, no luck.<br /><br />Could it be <br />Fuel Pump?<br />Therm ?<br />or big items like, cylinder, head, etc?<br /><br />Thanks for any info.

Re: Missing when warm

More than likely, timing issue. Check all timing linkage for "play" first tho.
