Fuel system and pressures HELP!!!! Please !!

[petesbuyin]

The die thing comes and goes. throwing the car back in forth to get heat the engine would die till the car leveled out. What am I looking for in this gasket? My engine builder took it apart twice and so did the carb person. just don't get why the fuel pressure goes down as it gets hot. electric gauge and mechanical . I took the whole fuel system apart. It's like the carb or something.

This is the difference between the two gaskets. Notice the position of the small holes. But after reading more of your posts, I don't think this is the problem. If you have the wrong gasket it will run bad all the time, not come and go. To break a piston is generally too lean or a timing issue. i agree with you about looking at the ignition system. With a MSD be sure that the pickup wire from the box to the distributor (or crank trigger) is NOT near the coil wire or any high amp draw wire such as the large red wire on the MSD box or the RF shut off valve. Just being close to these wires can cause an induced spark and erratic running engine.

Do you think it is a carb problem? Run ok on the track at speed?

Where are you from? Maybe someone is willing to loan you a carb to try if you think that might be the issue.

just seen that the carb is making little bubbles in the bowl during higher rpm. coming up the bottom of float. I put hose clamps on my push lock feed line since this. Have not bumped the fuel pressure up to 8-9 yet to see what happens. was around the 6psi mark at 5000rpm. Electric gauge, mechanical is bouncing from 3 to 6 on the fuel log.

I 've used 1 kb carb on the dyno, while it made good power it was lean and would not respond to jet changes as it should have.IF the carb will not idle check that it has a small hole drilled in each throttle blade.Turn the carb upside down and you will see a small slot by the blades.the slot goes up and you will have to open the blades to see it.Adjust the idle speed screws till you have about .040 of the slot showing below the blades.Check the ldle air bleed at the top of the carb(outside jets)they should be around ..070 ,smaller makes it richer.
