You will get more power by going with the wt-257 carb. By going with the wt-257 you are going to loose your choke and primmer bubble. This will make it harder to start the motor.

Do I need to just plug the return line? and any pointers on starting without a primer bulb?

You can either plug the return line or use a y spliter and run both lines into one. If you have an aftermarket air filter you can get a choke plate. I've found that you can pull the filter off and plug the hole in the carb with your finger and give it a couple of pulls and it will bleed the line. Once you bleed the line it is not very difficult to start after that.

Is there any advantage in using a fuel line y splitter over just a single line ?

One last question ...the black fuel line is very soft and flimsy compared to the thicker heaver yellow return line...is the reason they do this so the line in the tank will flop around easier if it turns upside down so it will still get fuel?

I like to use the spliter because you don't have to worry about the plugged line leaking. I'm not sure why the black line is softer then the yellow line.

Ok I got the 257 carb on seems more responsive and the DDM 7500 spring is sweet. One idea I have that might work is using an inline bulb on fuel line to prime engine ...there are some I see for nitro rc stuff, but they may be too small ...I think I need bulb with 1/8 barbs and I see only bulbs with 1/4 barbs I think thats too big.....I used DDM fuel line, what size is that line anyone know?

Most fuel line is 1/8. An inline primmer bulb should work if you can find the correct size.
