What you want to do is mix some dish soap with water, and using a paint brush put some of the solution on the engine on parts that could leak. I.E. Needles, Carb, Backplate... Then blow into the fuel line. It helps to take the pipe off and seal off the exhaust with your finger.

I need some ideas on getting rid of the low end bog on my B5.

It was really bad and then I changed my pressure line and it almost went away, but it's still somewhat there.

Here's is what I have checked so far.
Lines,
Tune ( I really don't think it's a tune problem)
Clutch
All bearings have been changed throughout the buggy
Cleaned out the carb

I really don't know what else to check. As much as changing the pressure line helped I think it might be a leak somewhere. I'm going to check the tank next. I've blown through it and it didn't seem to have any leaks, but I'll put it under water tommorow to make sure.

What are other places I could seal and what should I use to do it. I did notice that a little dirt was holding around the bottom of the high end needle but I don't know how to check an engine for leaks or what to use to seal up any leaks an engine might have.
And what could I use to seal up all the spots that a fuel tank could leak at. There was also a little dirt holding on around the pressure line nipple and that could possibly be the problem.

I'm almost betting that it is a tank issue because I have had really bad luck with fuel tanks so far with my RC8. I actually got a jammin tank becasue the AE ones were bad both times I got one. I even have a friend that got a brand new RC8T today and there were bubbles in his fuel line.

Everyone keeps telling me it's running great, but I remember how it ran before this started happening, and it's nothing like it was before. It's almost like the clutch is engaging to soon, but with all the power the B5 has down low I really can't see the clutch bogging it down like it is. I checked the clutch and everything looked fine.

Anyway a list of things to check that could cause a low end bog would really help me out.

B5 w/2013 is broke in. Got a race going to this weekend. This motor has wicked bottom end, I am thinking of gearing up from 13t to 15t but I will see how it does at the track first.

Your low end bog isnt caused from any of the above. If it were any of the above it wouldnt run at all...... You could be using to heavyor to light of clutch springs.... Does it just low end bog when its cold. If it does thats normal if your running a fat bottom end. It should go away after it warms up. I still say you have somthing out of wak on your tune. Low end bog is usually because you have a fat low end. Lean it out 2 hrs and go from there. Mine did the same thing and thats all it took. If you want to leave the bottom fat thats fine lean the top out a couple hrs and go that way. Its really simple actually. The bog is caused from either to much or to little fuel you just have to figure it out.

I've tried leaning it out and it doesn't take it away, it actually makes it a little worse.
