I finally got my motor back together and went out and tested it. I am running the 70 Yamaha carbs on my Tohatsu 50. I linked the carbs and set the fuel mixture to about 1 1/2 turns out. The motor bogs down when taking off and is hard starting. I had it easy to start and sounded good in a barrel. My main jets are 145. Do you have any advice you could share on where to go or what to look at from here. I have the jet ski fuel pump as well. The carbs have been rebuilt and I'm running the same coils as you did. Thanks for your help. Also how long does it take to set the rings? I'm running the TSR head. I checked compression and it is. 135,115,100. I only had it out onetime. It still has the stock Pistons with new rings and a freshly honed cylinders.
