Looper Shutdown with a rattle noise

What you have there looks correct. Make sure and replace that tee in the line that runs from the bottom to the top though, if the check valve goes bad you can starve the upper bearing of oil.

Guys, I fired the motor up in the driveway today , sounds great and starts very easy, problem is she now idles at 3000 RPM with the butterflies completly close and the idle adjustment screw all the way in!
I am currently jetted at .32 for idle and .20 for intermediate
Reason for me asking is Boyesen instructions mentioned on Evinrudes I must reduce the idle jets .5 sizes down and I did not, also I am over jetted currently at .32 hopefully that make sense due to Ferm and I addressing a loading up issue on the old power head which has since blown up and I replace with this new one and I did not downsize on the idle jets
Question is has anyone experience this before? If I reduce the idle jets will this drop my idle rpm's ?

Yes. Chances are it is running pretty lean and will sneeze on you pretty badly when you put it in the water. With the BOYESENS you need to keep it jetted rich as a lean sneeze WILL blow out the BOYESEN reeds(The TDR's don't seem to suffer from this as they are MUCH thicker and made from epoxy). IIRC stock idle jets should be 28's, I would start there and see what she does. Also remember that after break in you will probably need to play with the jets some. I would also swap out your mids for a set of 16's or 14's as the 86 140 carbs were known to be lean in the mid range and would occasionally stall on accel. And run 63's in your mains if the engine was bored.

Ok I will down size the idle to .28 and the mid to .16 and test
Thanks

what mains do you have 62D? as ferm said get the 63's and you are running double oil right. you need to run double oil for the first 25 to 30 hours and no WOT for more than 40 sec on water until you have about 15 to 20 hours.

Ok thanks, my high speed jets are 64d

Double Oil ? Is this 100:1 ? I ran 40:1 for about an hour now the engine at times will not turn with the starter seems tight ? I can however turn it with my hands and she fired right up. I am afraid the motor is locking up on me so should I increase it to 100:1 the rebuild company told me to use 50:1 , I decided to play it safe and run 40:1. Your thoughts ?
