I S I Barney Darney Oldfield I Can I run an Kent Atwater ent system ot of ignition from a l Ford magneto in instead instead In- In stead of ot a n Hot Shot battery If It so please 1 0 a 1 few hints on wiring I will uso use a Ford runabout t car i P. P T T. You Tou cannot operate the tho Atwater Atwater- You Kent from tho the Ford oord magneto need aced a b battery for tOr the Kent Atwater c Barney Oldfield My car has made mado miles and has hns just been repaired but does not develop cv lop any power Cylinder ClInder No 4 is always smeared with oil Tho The spark plug when removed gives give a. a good spark but when In place falls tans to fire I tried the spark s gap S-aP ap both wider and closer with no better re re- re suIt sult Will you kindly give gl me some Information to remedy this trouble S. S V. V In tho the first place cylinder No 4 is probably pumping oil due t to poorly fitting piston and rings or perhaps S Sto to a worn cylinder clInder The lack of ot power may be caused by the failure of ot this one ono cylinder I would reduce tho the oil level slightly uso use heavier r oil on and use n. n good plug in tho the hope of ot overcoming the tho effects of ot the oil If It this does docs not help the cause must be attacked Barney Oldfield I am m unable to get the differential of ot my ray car adjusted properly It makes m considerable noise and I have had it to several garages es without relief only to my p pocketbook I i had a n. new bearing and shaft pat put In and since that time have havo been unable to get set It adjusted so o as u asto asto uto to do away with tho the noise T. T V. V It 19 b a most difficult matter to tell how one should adjust a a. differential which at best is a delicate Job even for a n. good mechanic The differential must be shifted so that the tho backlash or play pIny between the gears and the pinion gears Is just jast right Experiment Experiment ment meat Is the only way to do this unless you can tell by tho feel or by measuring meas meas- with a 3 thickness gauge g-auge if it you yon havo it right t. t You must be sure that the gears arc aro a a. pair pall and therefore de designed de- de signed ned to operate together Never buy ono one new gear Sear to to mesh mesh with an anold anold anold old one get set a n. pair In your case I would try different adjustments a slight until the noise disappears Barney Oldfield Can you enlighten me as s to the cause of my car trouble in the clutch o of my car when I am at be between be- be tween 25 20 o- o s miles an hour bour and slip In tho the clutch It makes a grinding noise Tho The same thing happens when I am rounding rounding- corners so I now use my foot toot brake and let tho the clutch rest G G. F F. S. S Tho The grinding Is nothing to worry about bout It be may caused by poor pedal adjustment or 01 by the thrust bearing I |
