Hey everyone,
So after reading tons of threads on coils, timing, idle mixture jets, idle speed screws, float valves, running rich, running lean and the like I still need to ask a few questions.
Problem statement:
After starting engine
- with full choke
- with timing set initially using the Continuity light / TDC method in Don's literature/videos. I haven't got to a point for adjustments at high RPMS yet.
- With a rebuilt carb
- With new spark plugs
- With idle mixture screw at 1.5 turns out in lean direction
- With a new Gas tank, new fuel lines, new fuel filter throughout the system
The engine just stops around 5 minutes or so. This is after I have turned off the choke and am just idling.
NOTE: It does not sputter in any way or die a painful death it just ceases to run. This manner of engine death also happened before I rebuilt the carb and I naturally assumed it was a blockage. Still might be, but who knows.
If I attempt to restart it it will usually restart immediately. And I can go for another few minutes. I just cant ever just idle for say about 20-30 minutes that I want to so I can fine tune things and set idle under load at the dock.
Further details:
-Facet Electric fuel pump purchased from MM
-FlameThrower Coil with 3 ohm resistance ( no ballast resistor as of now )
-Seems to be a light sheen on the water that looks like maybe fuel, but not so much the EPA is after me.
-Rebuilt Exhaust Riser, clean as a whistle
-Plugs are a little black and partially sooty, definitely not TAN as some people describe but I wouldn't really call them dripping wet either.
-I do not have inline mechanical pressure gauge although I intend to get one installed pronto
- I do not have a TACH
Thoughts ?
Any tips are highly appreciated. I am so close I want to run this engine ASAP.
thanks
