Hey guys I finally got my car out yesterday for the 1st time this year. I had to rebuild the engine and I upgraded the brakes over the winter so I was pretty anxious before hitting the track. Luckily everything went very well and the car ran great. The 60 ft's were off almost a tenth from the fall but the track was green and the wife could see the car black tracking all the way down. The car still picked up about 2 MPH over last year and there was a pretty nasty crosswind so thats encouraging. I was hoping to pick up a bit more ET but I think it will come as the track conditions improve. Anyway a couple things I did have trouble with. The car idle's fine but if I rev it up to clear it out the idle doesn't come back down. It kinda takes off on its own to 2500 or so. Its fine in gear the idle stays pretty steady. Also the car was very hard to start a couple of times. I'm kinda thinking a needle seat could be sticking but they were just replaced in the fall. Plus I never changed plugs and I probably fouled them out trying to start the car over the winter funny story (I left the car outside while we drywalled the garage but it ended up snowing 6" while we were working and we couldn't push it back inside so I tryed to start it. Note it won't start on E85 when it 20 degrees out. We ended up having to use the CRV to push the car through the snow back inside - that was crazy) Anyway could the air bleeds be a factor? I haven't changed the air bleeds from the factory gas settings after using the Quick Fuel kit to switch to E85 last year. Whatcha guys think? I only have a couple more days to tune until the Classic. I can't believe its next week.

The rpm thing sounds like a vac leak... what jets are you running... and yes the E-85 summer fuel doesnt like to fire at 20*

I would be surprised to see the gasoline air bleeds working with an E85 conversion. I would think they would need to be smaller, especially the idle air bleeds.

guess i should read the whole post before replying. as you mentioned i can't see gasoline calibration working with the e85 but have no experience with it.

Take some advice from someone that has been thru a carb shop that said he knew how to convert a carb to E85.He did not and the carb was total junk. Then I posted on here and was given a number of a guy that does E85 carbs. Air Bleeds and emulsion tubes and idle circuit all have to be done. Send me a PM if you want the number of the guy that fixed mine. Mine came back and ran almost dead on. All we are doing is a bigger jet size. He had mine done and back to me in 4 days and was very resonable on the redo.He almost had to start from scratch.
If the MODS did their job I would not be hitting the notify MOD button. LOL

It has a mechanical only advance Mallory Unilite distributor. I didn't take my light so I couldn't recheck the timing but I'm going to check that again.
I think the sticking throttle blade sounds most feasable - maybe the secondary is staying open just a bit.
I don't know about changing the boosters because then it wouldn't be easy to switch to gas if I ever needed to.
Boosters are pretty east to change

Don't you need a jig to change them? They are swedged in and once turned to alky can't be turned back to gas???? Thats what I was told anyway....

Nope and nope... go onto Holley's web site they have a step by step of booster change
