| R.R. CDE (EXPTS) D.87A (D.{John DeLooze - Company Secretary} 1823) 12-23 EXPERIMENTAL REPORT -2- Expt. No. REF: GH12/Cml4.8.25. Controls. These have functioned O.K., and are in good condition. Inlet pipe to L.O.P. E.51767. This is in good condition. Exhaust pipe & fittings to L.O.P. E.51605, locking device on exhaust pipe to cyl.bgy. Exhaust box and pipe are in good condition. We have had a C. & A.{Mr Adams} washer on Nos. 3 and 4 cylinder ports partly blown out, causing bad exhaust blows. We have fitted a new C. & A.{Mr Adams} washer. Examination of pipe does not show any reason for this. Engine suspension. Front and rear suspensions are O.K. Tie tube for starting handle and front suspension, situated between first and sec. cross members - the two bolts that attach tube to cross member had worked loose. These two bolts worked loose on our last test. We should recommend that some locking device should be used for these. Carb. and fittings to L.O.P. E.53300. These are O.K. Carb. has been dismantled, and was found to be free from any foreign matter. With low and high speed jets set to give max. speed and good slow running, there is a weakness on picking up. There are one or two pops back into the carburetter before the engine gets away. Fan bracket, fan, and fan belt. These are in good condition, and we have had no trouble whatsoever. Fan belt has been tightened up half a turn of adjustment screw. Slipper drive. This is working satisfactorily, and appears to be O.K. Mag. and drive to LeC.2088. This is quite satisfactory. Dynamo. Dynamo has ceased to function twice. The cause of the trouble is dirty brush holders which has caused the control brush to stick. There is a hole drilled on top of brush cover, which when engine is washed down is liable to let paraffin, etc go through, and so on to the brush holders. We would recommend that this hole should be underneath, to lessen the contd :- | ||
