1987 21 BR Project
Re: 1987 21 BR Project
Replaced the battery cables today but that had no effect on the situation. Still labors to turn the engine over. It typically turns over only maybe 2-3 times before I turn the key off. Anyway, guess I'll pull the starter tomorrow. :/

Re: 1987 21 BR Project
Did you get the timing set yet? Does it run?

Re: 1987 21 BR Project
Yep, it ran. Several times throughout the day in fact. I purchased a timing gun later in the evening and took a stab at adjusting the distributor, adjusted it too far and the engine died. I nudged it back the other direction and called it a night. The following day it never could get enough juice to fire up. Now that I think about it, it wasn't cranking super great the day before but it was enough to get it started. I'm guessing the starter is toast but could it be a timing issue?

I should have taken a video of what it sounds like. Maybe I'll do that tomorrow but in the mean time here's a close example.

That's a timing issue.

Eh, it's the closest example I found to what I'm experiencing.Big Block Power wrote: Sat Aug 15, 2020 9:20 pmI'm like wait what engine do you have in this thing. Dohc?

Re: 1987 21 BR Project
In my one attempt to set the timing with the gun, I retarded the timing too far which caused the engine to stall. While I did rotate the distributor back the other way maybe I didn't go back far enough.

Re: 1987 21 BR Project
At this point I would just pull the distributor, set the engine to TDC on the compression Stroke #1 cylinder then reinstall the distributor and start over.

I think that's good advice and I've considered that a strong possibility too. I'll give it a try.akorcovelos wrote: Sun Aug 16, 2020 2:21 am At this point I would just pull the distributor, set the engine to TDC on the compression Stroke #1 cylinder then reinstall the distributor and start over.

Nothing you need to worry about with all your garage boating.

Re: 1987 21 BR Project
Removed the distributor and reoriented it back to TDS. I'm not sure if I was off before or not but it was worth trying. Running and starting seems better now but the timing still needs adjusting as it ran for a minute or so then stalled.. I'll pick back up where I left off later this week.

Was perusing craigslist a bit ago and saw your listing for this. Sorry to hear it got to be a bit overwhelming

Re: 1987 21 BR Project
I actually had a change of heart yesterday and took the posting down. At the end of the day I still need a project to tinker with so I'm going to keep plugging away at it. Working on the boat is better than any honey-do the wife comes up with
. I do think I'll outsource the remaining timing adjustment because I just can't seem to get it dialed in just right. It starts but won't idle without throttling up. A carb adjustment may be needed, i dunno.
What pushed me over the edge of frustration on Saturday was the discovery of a small amount of gas sitting in the ski locker. I had put a few gallons of fresh gas in the tank when I started the project and did notice a very strong gas smell but didn't see any evidence of leakage. Well, that's because the bow was sitting lower and the spilled gas had moved to the bow and not out the back. My guess is that the fill hose needs to be replaced as it's deteriorated over time. I need to replace that section of the floor over the tank anyway so getting to the tank shouldn't be an issue. Just another task on the to-do list.
