I have the metering blocks done but have a question and I can figure it out if I take a bowel off my other carb but the car is in the trailer and can't get the hood off in there so here's the question..
The metering block vent does not have a hole in the top where the pin holds it in place so where does it go as far as depth?? Kind of looks like it should be flush with the other side but though I would ask =; first...

I also got the main body done with the boosters installed..

I also made a tool sort of to press the boosters into the banjo's
5/16 bolt with a piece of delrin (sp?) on the top so it don't scratch them up..

Looking good Barry! I think my vents are flush with the main body side of the metering block.

At this rate you'll have the car fired on E85 by the weekend.

Thanks Mark, Going to race on Saturday and going to stop by and get a gallon or so of the E85 and test it when I get home to see what it is....

Barry, what do you mean by flush?

I'm missing something here.

Forget it. I re-read the post. I do it like mslayton described.

My E85 carb is just about done as all I need is some jet extensions to finish it up but may just fire it up with out them to try it so If I have any issues I will be able to get some help here before I go to the track..
I also have 2 clean 55 gallon plastic alcohol drums so I am ready to go...

I was thinking :- I can use the E85 that only tested to 70% to flush my system out..
Sound like a good idea??
Also How long can I leave that stuff in the tank or carb??
Should I run it empty as far as the carb and spray it with WD or something??

Yeah, that 70% would be fine to purge the system.

On methanol I drain the bowls after I unload the car. I don't think it's good to leave those nitrophyl floats soaking in that stuff. You can do this by running your's out of fuel with the electric pump off though. Otherwise, I don't do much else with it.

If you're not going to be racing for any extended length of time it might not be a bad idea to drain the fuel system. Not sure how pump seals will hold up either although with 15% gas in there it "might" make it much easier on the system in general.

I NEVER start a methanol engine unless I can fully heat cycle it, ie, I never shut it off for the last time unless it's up over 200* water temp.

On my last pass of the day, I usually shut the water pump off on the return road and drive back to the trailer.

I also disconnect the evac hoses from each valve cover to allow a path for moisture to escape. On the injected BBC I had I pulled both valve covers off after I loaded it and left them off until the next time out but that thing would be full of crap and it took a while for it to dry out. Carburetors with a lean idle don't generate that much condensate though.

Then once a day for the next few days I'd use the starter to roll the engine over to help prevent rust in the cylinder walls.

Don't know how much of this would apply to ethanol though.
