Intake tube stretcher
« on: May 09, 2008, 02:34:29 pm »
The carbs went on easy, my OE carb insulators have held up pretty well. But I was having a heck of a time with the airbox. The intake tubes are as hard as a rock. I've been keeping them oiled in hopes of softening them, but it didn't help nearly enough.

A golf ball is 0.100" bigger than the carb opening. I shoved 'em in and gave it 5 minutes at 200f, then shoved 'em in some more and another 5 minutes in the oven. The golf balls kept it warm until I got outside. The airbox went on as easy as pie.

Great use of golf balls. I never seem to be successful with their intended use. :-\

Maybe you recognize one of them Bob, because they've all been lost - and found - at Leslie Park. :D

Actually, I finally gave up on golf. My performance never even came close to my expectations. :D

I have race cars and had some tire softener sitting around and soaked some boots. After a day they still were hard as rocks. Then i realized the tires don't work until you get some heat in them. So I use a heat gun(wife's blow drier) and they was as pliable as new. since then, I have developed my own softener . but basically its just laquer thinner and trans fluid. hope this helps!
