Evening all. Took a new to me boat out today for its first sea trial. It would idle ok, and then sneeze every so often. At wide open it would rev to 3500, surge to 43, drop to 3500 and do that over. Everything felt like a timing issue. But for the life of me I can’t find a manual online. Best results on setting timing I can find is this link from another forum.

anyone with a similar manual, walk through of link and sync, whatever would be extremely helpful.

thank you in advance!

Got the timing done properly through the boat info manual. No dice. Pulled the carbs apart and they were GUNKED up. So test run 2 tomorrow.
