Barney Oldfield: have run my car only 5000 miles, but when I speed 1t up to 12 or 16 miles per hour, 1t tstarts to flutter. put on a new carburetor and refaced the valves, and the valve seats on the head and also ground the valves in. l put new Baskets on the manifold. Now do valves work when they leak? How would leaky gaskets show ?-E. G. E.
 It appears from what you say that there is mixture dilution due to leaky intake manifold, or cylinder head. In the car you have the manifold is T-shaped with welded joint and very often the well while apparently O. K. is leaky. I think if you will change manfoIds your troubles will be over.
 Barney Oldfield: After having con siderable trouble with my car (Crowelk- hart) Maybe you will be able to tell me what is wrong. When l start my car it runs only about 10 minutes and sometimes less when it dies right down. All the wires seem to get hot and smoke. was told a new coil was needed, so got one, but is still acts the same, I also got new spark plugs. was also told it was the fault of my batteries so had them recharged. Do you think have it connected up wrong. When 1t first gave me trouble it would hit on all four cylinders, then on three, two and one and finally stopped al- together. I cleansed out the gas pipe and it did fairly well for a while.- W. W. P.
 The trouble doesn't sound at all like ignition, but seems to be confined strictly to the fuel system. It appears to be due to obstructed fuel line, or to q vacuum tank that is not working properly tone that is unloading into the intake). Change vacuum tanks as a trial and am sure the engine will run O. K It does not matter which way the matter is connected.
 Mir. Oldfield When the crankshaft is lined up with the camshaft marks, and when the chain is put on it throws position about one half tooth forward the camshaft slightly backward or next ward. What effect would the forward position have on the engine? Would it have any effect on the powerful. M. H.
 The slight variation will not give much change in engine performance.
 Dear Sir: have a touring car that had been run about 15,OOO miles. l had no trouble with it until about three months ago when found that the spark-plugs were firing at the end of the procelain. bought set of new plugs and two of them did the same thing after running a while. l took good care in placing them-so l would not crack the porcelain. What do you think is the cause of this trouble?-J. c. E. H.
 I cannot explain why new spark plugs will fire across the porcelain unless the porcelain is cracked Per haps. I misunderstood. your explana- tion but new plug with porcelain un- injured cannot fire except across the gap. There is no other way for cur rent to flow.
 Dear Sir: Your article on super chargers is of great interest to me and I would appreciate a copy of the diagrams that you mentioned. Any other information that you may have on this subject will be appreciated, such as R. P. M. of the superchanger Tn rela- ton to displacement and most inn portant, screen or seive to remove dirt and dut from input.
 Could regular fan be used with an enclosure around it to furnish air to the intake of the superehanger? Would this be an advantage? The above information is wanted for use on reconstructed Ford racing car bore changed to 3 :95 by stroke turning up approximately 4,000 R. H. M. to be used for dirt track racing.-C. J. $.
 am sending you separately a diagram of a superchanger installation. A, superchAager is nothing more than blower so connected that when it starts to operate an additional jet in the pcarburetor comes into play 50 as
