I will bring yer HEI and all Jasons stuff too, and the module i have. i will also bring my fuel pr gauge and of coarse i go no ware with out a bunch of tools.
make sure you drag yer extra fuel line stuff (hose fittings clamps) just in case
WE WILL GET IT GOING !!!!!!
Yeah Ill be bringing a bunch of stuff. I'll be stopping at West Marine on the way to pick up some more 5/16 line since that is what fits nicely over 5/16 steel line which is what I have running to the carb.

Ross is your key switch 3 or 4 position? I have the old one from Phoenix Rising we could bring with us that was working well when I switched it out this spring. If it comes down to that.

I guess its 3 if you count "off"
That would be great. That is one thing I don't have extra of. Did you switch yours out as part of troubleshooting? So you know its good?

I just switched it because I put in a radio. So now I can listen to it with out putting power to the coil. Yep I know it is good!

Ah... an accessory position. That is something I may consider in the future.

So we can by pass the resistor then for a short time to verify ALL wiring and components are good.

I'd say so. I'll bring all my info from this stuff too.

Ross, i know yer frustrated with this problem and feeling like you have done lots of stuff that hasn't fixed it. keep in mind the fuel tank issue would have had to be addressed anyway, and now you know all yer lines are good.

when we worked on it at my house, and when we were on the st croix i believe it was verified as a fuel issue (at my house observing low fuel pr on the gauge,  and on the st croix by Jeff observing no accelerator pump squrt after it killed.

i realize the only component in the fuel system that has not been bypassed is the filter, though i doubt it could be that.

also keep in mind we could be struggling with more than 1 issue or bad component, and something that is new or rebuild could still be suspect.

lets plan on installing fuel pr gauge and Jason's spark tester and test those things tomorrow. i am going to try to get out of the house by noon as i want to water test mine some on Thursday as well.

Frustrated is putting it mildly. Yep, absolutely we saw the fuel pressure drop to zero and gradually build back up. I don't know if its possible that something "upstream" of your gauge could cause that. The only thing upstream is the carb and filter.
You mean the filter in the carb...thats the only one that hasn't been bypassed. I agree it could be more than one thing. You'd think the symptoms would change a bit if one of say, 2 or 3 problems were eliminated.
It doesn't help that none of this can be done on land either. Every thing I change requires a trip to a lake. Could leave it on the trailer and run it. That landing is wide enough for 2.

Extra bodies and eyes always help. Checking for spark before during and after it croaks would be ideal. May need a "support" boat. I've had enough of a dead boat in front of barges for my life time and dropping anchor might not be an option unless closer to shore.

Yes support boat and people is what im talking about.
we go out try it fix it or tow it (BTW i got a nice 1/2" by 50' rope and put nice hooks on it)
when i said filter i was speaking of the racor filter separator.
im not saying it is bad, just that when it appeared to work at my place that was out of the picture.
seems to me it ran way longer at my place after switching to elect pump and gas can then it did on the st croix after it started acting up.

Agreed and although I have replaced it (25.00 each) we just might want to by pass it. I may have to run to Menards unless anyone coming has the parts needed to join 2 pieces of rubber line, such as a bushing and 2 3/8 barbs.
