Ummm Mini Stock...

How do you test the chip then? They all have their issues.

 

You test them with a chip tester. I'm kinda fond of Mr. Pringles myself, but there are a lot of Lays Original Chips fans out there. And I volunteer to be the first chip tester since I have a lot of experience testing chips.

Mr. Pollaro,

 

I am sorry if I spelled your name wrong, I didn't mean to offend you, but I consider Chris Brandes and Robert Barker very good friends of mine and have known them for many, many years. and I did not think they would mind me using them as an example.

Sorry if I offended anyone, but you brought me into this in your above post. Both those carbs. were freshened last year and from what I recall the epoxy in question was not an issue back then.

It sure would have been nice to know when the epoxy became an issue. Could have avoided a major controversy for the track officials.

Robert,

The carburetor that was on your car saturday night was not my carburetor. I know Dan from VDL and I am sure he had no intentions of causing you or others an issue in tech. As I know he also works very close with Jack to make sure his carbs. pass tech.

 

Sincerely,

Greg Spreen

I wonder if THR will issue a bulletin on the approved method for removing the epoxy. Otherwise, some racers will try to use Methyl Ethyl Ketone (MEK), or acetone, or xylene.... along with some form of heat to soften the epoxy. Some of these chemicals are very dangerous to breathe and absorb in your skin.

On another note, we have an approved method per Jack from THR this week of removing the epoxy off the boosters, we have already done a few this week with no problems.

 

Greg Spreen

 

Can I recommend you get something in writing from Jack or THR so those that have the epoxy removed will have some assurance it will be approved next week, next year, or in the future. Not stirring the pot, just skeptical.
