RE: {Chrysler 300} Accelerator Pumps

[Noel Hastalis <cpaviper@xxxxxxxxxxx>]

Several years ago I met fellow 300 Club member, Don Verhoff, up at the Iola car extravaganza, who had his sweet black 300-G coupe on display. Don's business was building diesel engines and strongly recommended running a few ounces of Marvel Mystery Oil in my gas tank with every fill-up. Said he used it in all his engines.

 

I had been addng it until I ran out last year - need to go buy another gallon! On the phone with Joe Jordan a couple nights ago, he also recommends it.

This is a trick I learned a while back, I believe I read it on the H.A.M.B. site.  Add  a small amount of  TCW-3 rated 2 stroke oil to the gas tank when filling up.  The ratio is 1 oz/5 gallons of fuel.    My engine runs great, doesn’t knock, and I have no carb problems when it sits for extended periods.  Most 2 stoke oils are TCW-3 rated, so its easy to find, I buy mine at Walmart.  Not sure what is in Marvel Mystery oil, but it could provide a similar benefit.

Just pull the carb tops. On the 300F it is about 10 minutes per carb. Be careful to not lose the two small linkage clips on each carb. Make sure you remove the metering rods before you take the carb tops off (and take your time inserting them after the tops are reinstalled). Then you can easily remove the "squirters" and unplug them. While they are off, work the pumps to make sure fuel is getting to the squirters. If you have not, while you are in there, make sure the floats are set correctly for height and drop. I totally inderstand the problems with California fuels, Arizona has it even worse. I have used Marvel Oil for years to add "lubricity" to today's very "dry" fuels. It definitely helps the valves seal in both mechanical and electric fuel pumps and may well help aliviate the sticking check balls in accerarator pump systems.
