Re: inspection nightmare
On the right hand side of the country, alcohol must be more useful for other things.

Re: inspection nightmare
Adding about 2.5 ounces of regular crankcase oil to 10 gallons of Model A gasoline will work just great for helping to prevent E-10 vapor lock whether MMO is available or not available.
Our old square tank 1930's- 1950's outboard motors "all" used regular crankcase oil before today's 50:1 two-cycle oil which was much later invented and recommended for 2 cycle engines. Last edited by H. L. Chauvin; 06-23-2017 at 08:45 PM. Reason: typo |

The pumps say "up to 10%". That is true. It won't be over that, but it can be well under that. Under hood temperature is the wildcard. Some cars run hotter than others. Sit at a light idling and everything under there (carb and fuel) can get quite hot. In these conditions, I have to open my GAV and start out from the light staying in 1st gear, holding the RPMs up until the outside air cools everything off under the hood. You can feel the power kick in and the engine start to run right again when the carb is cooled off. Then I close the GAV back to normal running position and shift to 2nd. If I don't do the above, the engine stalls leaving the light.

Re: inspection nightmare
I run real gas and still have the problem stopping for a fuel stop on a tour on a hot day. I use MMO and it helps some. I found if on a hot day on tour I fuel... open hood and poor cool water on the fuel bowl (Not Ice Cold) and no issue. About a half bottle seems to do the trick. I would be afraid to poor ice cold water it might crack the fuel bowl. Also just letting it idle for about a minute or so will cool it down but seems like on tours folks want to roll right away.

As such I have enjoyed some people relating stories as to why they do not believe either in PM's. So on person related to how they had the typical engine 'vapor lock' problem for a few years. He tried all the fixes and none worked really. Then he had to take the engine apart for other reasons and he noticed the valve gaps were done wrong and uneven. So he redid the valve properly. When he put the engine together no more vapor lock. To approach this logically you have to think well only some cars ever have a problem. So on a tour a couple of cars are having a problem and they are all in the same conditions with the same gas. Right there tells me it is a build problem. What goes wrong, well that is the problem. What is more likely wrong is a bunch of little things. Timing off a tad, valves slightly off, maybe the water jacket is not cleaned out as well as it should be and they all add up- sometimes- to cause a problem. How many people are aware the valves need to have the gap set for how the metal expands. You can not just go by what the service bulletins say. You have to know the expansion rate of the metal. Doing the A engine right is not simple. People do not realize the A engine is a high precision built device. They poo poo that thought and think it is just an old engine why bother with accuracy. You really have to think your are building a race car engine as you approach the constuction of the engine. The A engine runs great if it is done right. You should not have to do any modern fixes to get it to be extremely reliable (well the burn out proof condenser is essential, no not the V8 one). |

Re: inspection nightmare
I was definitely in the camp that said if you have fuel problems, there must be something wrong with your car because it doesn't happen to me. Until... going up Mt. Mitchell off of the Blue Ridge Parkway. I also had similar problems in Mississippi after hours of sustained 50mph driving. At one point I noticed rolling bubbles in the sediment bulb. It was hard to take a good picture of that, but I did get a picture of the giant bubble that formed as the moving bubbles stopped. I had a couple days with similar conditions and with multiple fill-ups per day I know it wasn't just one particular tank of gas. Higher octane gas didn't seem to help. It pains me to say it, but after adding MMO the problem went away over the next couple of days and 1000+ miles.

Barry B.
It might just be Inspection Stations. I too have suffered a dented ego at the same locations. I have long believed the remaining Model A's are here to keep us humble. First sign of a puffed up ego, they have a knack of embarrassing at the perfect spot, ie. Inspection Stations, entrance to the Hershey Show Car field on Saturday etc. John Carter; Great site about your tour through National Parks. I'm satisfied if I make it to the next town & back. Wife no longer wants to ride as she is tired of driving back with strange men in the front of a flat bed truck. Yup, it's tough...... JB |

the same as adding ATF to your fuel, its not really designed to burn clean. you are much much better off adding MMO or a good brand 2 cycle oil to your fuel for good upper cyl lubeing |

Re: inspection nightmare
If you decide to use ATF, avoid the types that have silicone in them.

Re: inspection nightmare
Wooden clothes pins on the gas line.
Some put tinfoil between the clothes pins and the tube. Don't ask me why it works. Joe K

Re: inspection nightmare
John_Carter, loved your blog of your long distance tour. Would love to do a tour like that myself. Thanks for sharing. Jeff

Re: inspection nightmare
well for me the reason to add some MMO or 2 cycle oil is for some top end lube as the new oils have no zink and other good stuff in them. to ea his own however
