Hello all! I've always wanted a standup and finally pulled the trigger and bought one. It's a 87 js550 that the previous owner just finished painting and "freshining" up. It's all stock minus a sbn carb.
The previous owner said after he put the sbn carb on it it would bog up top. I checked compression,125 on both. It started and ran yesterday when inspecting it. Started this morning also. When I went to the lake we put it in the water and it started right up. Rode it about 20-30 seconds and it died. Wouldn't restart. If you gave it full throttle it would act like it wants to run but would bogg and die. We pulled it back home,and out of the water it fired right back up.
I'm going to rebuild the carb and check/change the jets. Can anyone recommend the proper jets? I'm at sea level if that matters. I'm hoping this will solve my problem.
I'm a mechanic for a living,but have little to no 2stroke knowledge. So any suggestions/help are greatly appriciated!
