TT Outboard Problems

Hello,

I am having trouble with my thunder tigre outboard, I seem to have a tuning problem that i cant shake. The boat wants to bogs at full throttle 1-2 seconds after it gets "On the pipe". I have taken the carb back to stock settings multiple times after trying to weed out the full throttle problem with hi and low speed screws. I am pretty close to making a wet tuning bench with a bath so that the prop has some kind of load on it. when running it on the dry stand with no load there isn't a problem. I have added a secondary tank since i was thinking this was a fuel issue of air in the feed lines. That did not fix my problem.

Any help would be appreciated. Thank you,

Richen the high-speed needle. Usually your best bet on the TT's is to leave the low-speed needle alone.
Stock settings are only a general place to start at. They have no idea where in the world their engines are going so there are a ton of factors that come into play. Nitro content, altitude, humidity and the temps of both the air and water are a few of the things that dictate the needle settings.
