shanYE west Posted June 1, 2009 Report Share Posted June 1, 2009 can neddles and seats go bad? i wounder if i should just get some new ones? You can buy rebuild kits. Take the needles out and look at them. Most of the time its just some junk up there keeping it from closing.. but I have seen the rubber rot off the end of the needles.

joee20002 Posted June 1, 2009 Author Report Share Posted June 1, 2009 Did you use the same oil in your purge fuel as you do your alky the last time you purged it? I believe Shayne is right on w/his explanation. That is the one good thing about a fuel pump...it is harder for this situation to happen. ya sure did Quote Link to comment Share on other sites More sharing options...
shanYE west Posted June 1, 2009 Report Share Posted June 1, 2009 syphoning alky out of your cases at the track is not fun... and it dont taste too good either... I think that was the Day you rented the track Damian! lol That day sucked so bad.. Quote Link to comment Share on other sites More sharing options...

blowit Posted June 1, 2009 Report Share Posted June 1, 2009 I would recommend drilling your own over flows into the carbs so this does not happen again. talk about a 5cent item causing 1K in damage. Carb vents up top will not prevent this but an over flow in the bowl will. You can also drill the bottom of the bowls and install your own dump tubes but make sure they will flow ENOUGH fuel.

shanYE west Posted June 1, 2009 Report Share Posted June 1, 2009 Brandon, You should offer this mod. Many people (me included) dont have a clue on how to go about doing this and dont want to risk ruining a set of billet bowls. Quote Link to comment Share on other sites More sharing options...

Let me know which carbs you are playing with and such. If someone wants to send over some R&D goods to examine, I will build a solution for the problem. Might PM me with some more details and a few pics and I can probably get you taken care of. We may just build the billet bowls from scratch. Not sure.

It would all be relative to your float level. Many times if you drill at the top of your bowls, that will not be high enough and fuel will leak out constantly. drilling the carb body at the highest point in the bowl area or adding a dumb tube from the bottom would be a better solution. Without doing the math, I would estimate a 3/16 dumb tube would be needed. B Quote Link to comment Share on other sites More sharing options...

B im not trying to sound like a dumb ass but when you say dumb tube u mean the tube thats drilled out for the main jet? im not to clear on that.. or do you mean the tube at the bottem like the stock bowls?

If you look at a stock bowl, you will see a vertical brass tube inside that you have to weasel around the floats. That is the overflow dump tube. Referred to as such because needle/seat fail to stop the fuel flow for some reason, it will "dump" the fuel on the ground, rather than in your engine. Every single carb made should have this built in. Just a smart idea. B Quote Link to comment Share on other sites More sharing options...

B ya it sounds like it should work...i wounder why these guys that make the billet bowls dont put them in there.. anyways were can i get the parts to do this?

I have not studied the situation as of yet but I would like some general plumbing components should somewhat get the problem solved. I would likely want to build my components from SS to reduce an corrosion concerns from Methanol. I will agree, a bowl without an overflow is NOT a good idea.
