New thread for this problem. First decent weekend since the fall, with the goal being to get on the water by Memorial day. Where I'm at:
1. Carb screws snapped off when I was trying to rebuild it, dropped it off at the machine shop around thanksgiving, I'm still waiting to pick it up.
2. Rebuilt...
You literally now have 3 threads going (with a conflict on what problem you're having) where you are either ignoring or not reporting the results of all of the troubleshooting steps being given to you
There are electric choke upgrades for the weber. Yes, you'll have to recalibrate your carb. Merc has a 3 step needle IIRC for the weber, not sure if they sell replacements still--last I looked, I couldn't find the specs for them. Otherwise the Edelbrock springs/needles/jets should work. A few of...
I'm not convinced your timing is correct still (might be the fault of the direction of this thread...). Looks like you're getting an occasional fire. Those compression numbers should start the engine, though it would be worth seeing what's going on in #6. You've obviously screwed with the timing...
Right. With my plug reads, I may be running richer than I need to be and wasting fuel even though it's running well. Only real way to do this with better than "horseshoes and hand grenades" precision is with an 02 sensor.
I might do that (we're going to continue to first work on getting it back on the water after its unfortunate attempt at becoming a submarine). I didn't have any luck at all with plug chops, and while they were nice and tan after the season, all that really tells me is that I'm in the ballpark...
I'm sure the electronics are light years ahead, the self tuning is cool (don't know how the O2 sensor would hold up, or if it's just for initial tuning and then runs open loop). Trying to tune a carb on a boat has been frustrating for me. Don't know anything about the fast systems, though it...
I looked into this when I did my 4.3, pretty interesting. I haven't seen any threads here with anyone doing this conversion. I'd be wary of any potential power/economy benefits with a TBI system, but it looks pretty slick. I don't think any of the "keep the carb" crew has any experience with...
Windy is pretty good. You can choose from different forecast models. The forecasts are hit or miss in my neck of the woods though, we get pretty severe and frequent shifts. Overall nice app though, I always check it before going out
I mean, it really doesn't matter, does it? Change the oil, roll the dice, see what happens. Better odds with better storage, but no guarantees regardless.
No, you have another issue. Oil residue isn't enough to keep the engine from turning over. If it isn't turning over at all, I would check to make sure that your valves are moving in that low compression cylinder. Otherwise, start with cleaning your connections and load testing your battery
Spin it with the plugs out, any oil will be expelled through the plug holes. Although if it's turning over, any oil will go out the exhaust anyway. I'd run it for a while and recheck the compression.
