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.If I reduce the idle jets will this drop my idle rpm's ?
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 ?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.
25:1 is double oil. I quit double oiling awhile back as I had 2 engines seize up on me from double oiling. Oil burns hotter than gas does and also makes your fuel mixture thicker which causes your engine to lean out under load. It will also cause excess carbon build-up if you don't run some sort of de-carboning additive through the fuel.
I would be concerned. Who did the build? Sounds to me like somebody didn't check the ring end gap and the rings are sticking once shut off. And 145 is not even remotely hot for one of these engines, IIRC it should be running around 150-160 at idle and then drop off to 100-125 above 3000.

They used to do good work, I used to use them as my machine shop as well. Was it Lou you dealt with or Vaughn? I have had some problems with pistons that I got from them in the past though with em sticking for no apparent reason.
