Starting fluid won't work

Unread postAuthor: jaspervandieman » Fri Aug 17, 2007 3:12 pm

I have a basic combustion gun that works 1st shot EVERY time with alcohol but NEVER works with starting fluid. I've tried all different amounts of starting fluid to no avail. I'm just trying to get more kick than the alcohol gives....HELP!

I'll try a fan in my next gun, but I think I might ce corrupting my electrodes with the spray. I'm going to try concentrating the starting fluid in something and dump it in like I do with the alcohol and let it fester for about 30 seconds before I fire. Wish me luck and thanx.

starting fluid is sometimes propelled with co2, so maybe that's the problem

Just use starting fluid no alcohol.
1/2 second spray should work.

Starting fluid often doesn't get spread around the chamber enough to ignite. A chamber fan should solve your problem, as well as increase performance anyway.

Is starting fluid that much stronger than alcohol?

How big is your chamber.

I find in smaller chambers, (generally below 100 cubic inches), it's a PITA to get the correct amount of starting fluid into your chamber. You literally gotta tap the valve on the can as fast as humanly possible on a smallish 90-odd c.i. chamber to get the right mixture, so if it's any smaller than that you're gonna have problems.

I keep hearing this "Chamber Fan" and I just don't know which kind of fan and how to power this fan and how to install this fan....
I can't find chamber fan stuff on the wiki =(
Anyone help?

A chamber fan is usually just a computer case fan in the chamber used to mix the fuel and air throughout the chamber. I'm almost sure that that is in the Wiki.

starter fluid works fine for me too, even in my first cannon without the fan. Just make sure your holding the can properly and dont spray it directly onto your electrodes.

I keep hearing this "Chamber Fan"
If you cant/dont want to install a fan I saw somewhere on this site you can get that plastic chain(white coloured) and attatch it to the inside of the chamber and give it a shake. Its a crude method but it would work, fans still rock though.
