Holley Squirter Check Vales sticking, Alcohol
 

Anyone ever have the check valves below the squirters stick on an alcohol Holley?

Rebuilt a alcohol 950 for a friend and it has come back twice with the front squirter not working. Replaced the check valve during rebuild and again after the first time.


What's the cure?

It's one of those polished all aluminum carbs without any protective coating on the metal surfaces.

See if you can find a brass check valve to put in it.

I just got some this week.

Do you think the shiny aluminum carbs are bad for alcohol because they are just tumbled and have no protective coating?

Yes they are more susceptible to corrosion than the zinc bodies. Having them coated helps...

I have a similar problem on an E-85 carb with a Proform main body. Where do you find those brass check valves?

If you send me your address, I will send you a couple.

Thank You Sir, PM sent, your willingness to help is appreciated. Brian

Parts will go out tomorrow

Parts received Thank You

Brass check valves in and still sticking. Guess I need to ditch the Proform main body and get a Holley with some kind coating or plating. I will remove the brass check valves because I don't want to be beating on the brass. Thank you though for the help from BigBlockMark.

You might try a stainless check ball the same diameter as the check valve, and cut the same diameter as the ball off the length of the check valve. Put the check ball in first, put the old valve on top for weight. Don't ditch the body, if there is an issue with the seat that can be replaced as well. You can get them from BLP or Quick Fuel, those bodies are the same that Quick Fuel uses.

thanks for the reply Mark. Sorry it took me so long to respond. Good info that I will try. Will keep working with this main body but i think I could use a little more cfm and was looking at some of BLP's main bodies. Thanks again, Brian

Mark, I went through my junk and found 1 check ball the right size at .156. Had others too big and too small at .187 and .123. Where would I have to look to find another .156 check ball? Brian

You can get them from McMaster-Carr online. Or if you have a bearing sales place close by they usually have them.

Thank You Curtis. I will give them a try. Brian

Check balls ordered. Had to order a quantity of 100 so I will have several lifetimes of this item. Was going to go to carb shops in Indy but buying 100 was cheaper than the gas. Thanks again and I will need that company in the future. Brian

jmarksdragster, do you have any time to work on a carb for me?

I don't know how often he comes over here since the change and drop off of users. You might be better off going to the site that is in his signature and asking him there.

Curtis

Thanks for the info Curtis.
