Bought this boat with a rebuilt engine (10hrs on new meter). Purrs on the muffs, but at the dock it starts and dies and then won't start again. Bring it home and after some time it starts and purrs on the muffs??? Happened twice.

Did you check the timing with a timing light?

No, I'm no mechanic (master carpenter though:) and probably have no business with a motor like this. I probably need to sell and get an idiot proof outboard or learn:/ The kid I bought it from in Tacoma had his VP mobile mechanic out when we tested it and I understood that the timing had been adjusted as well as valves, new ignition, and thoroughly shop tested. Can you recommend a good mechanic in the Whidbey Island area?

First, I just want to thank you for taking the time to respond and for the service that you provide. I truly appreciate it! Update, it's starts right up when I put a little gas in the carb. Got some 3/8 ID clear poly from the Home Depot and spliced on boat side of fuel pump. I also drained the separator and the contents were redish, but did not separate. However the fuel through the clear poly is not amber colored. At idle a consistent stream of 64th inch +- bubbles came from tank and hose. But, the motor is running very well. There is a tee just inside the motor well, presumably for vacuum test in the past. I'll test that with soap water first before pulling up the tank access, as I just finished sealing it off with 4200. Thanks again, and I will continue to learn from your stickies.
