Acetone for Starter Fluid - 03/08/14 02:06 AM
My 528 Hemi is a pain to start if it's cold. It has a Speed Demon on an Indy 426-2 manifold and MSD 6AL ignition. If it's been setting for a while, I have to crank forever to get it to fire, and usually by the time it does fire a couple of plugs will be loaded up and it will run rough for a few minutes. I have an electric fuel pump so the bowls are full when I go to start, and I have a manual choke but I have to pump and pump the pedal to finally get it to fire.
So today I did some checking to make sure I had spark when it was cranking (sure did. Ouch!). The accelerator pump was squirting fuel. No start. So instead of cranking and pumping I poured a little acetone in each of the barrels. Hit the starter and Boom! it fired right up instantly hitting on all cylinders.
I know acetone is one of the things people talk about as a fuel additive but it does little good to put it in the tank because it evaporates so fast. So, I may just have to put some is a squirt gun and go though this routine on cold starts. Better than wearing out the starter. I may try xyol next time since I read of it's use too but the acetone sure worked good this time.
