Re: {Chrysler 300} Accelerator Pumps

Many years back, I had a small, two cycle outboard boat motor on a sailboat and it would quit about a mile out from shore time after time. I took it into a repair shop, and the guy asked me what kind of two cycle oil I was using in the fuel. I told him it was just normal 2 cycle oil. He explained that because the boat motor was constantly cooled by cold lake water, it needs an ash content in the oil to run well. Once I switched over to the true outboard 2 cycle oil, my problems were over. So I guess since we run our engines hot, the regular would be the right one to use.

I saw a you tube video comparing marine 2 stroke oil to regular 2 stroke oil in two identical chain saws. There was virtually no difference in performance. The only difference is that marine is much more expensive.

Thanks everyone for all your recommendations. After trying various ways to get some carb cleaner into the system without disassembly, nothing was really effective. So I ended up taking both of the carbs off and dissembling them yet once again. Given all the tiny clips on some of the linkages, I ended up taking the carbs off the car so I wouldn't lose any clips or struggle with trying to attach these tiny clips at weird angles while the carbs are on the car.. It takes me a little more than 10 minutes to get the tops off but not much - it's getting things back together that takes me more time.

I am not sure which of the responses above are from folks who use gasoline containing ethanol or not but it seems to be safe either way, it would be best to add some TCW3 oil with each fill up to avoid issues in either case, so that is what I will be doing in the future. Thanks for all your input.

I also use a few onces of Marine 2 stroke oil TCW3 every tank of fuel and never any problems.

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.
