I would appreciate any help that would make the unit operate normally. Problem: When pulling the starter rope it does not pull out as normal. It comes ot a short distance and with continued strain it gives a bit and does so again till it unwinds completely. It would seem that there is a build up of compression in the unit either in the up or down stroke. It does not fire. Checked the sparkplug by earthing it to the engine and removing the cutout wire from the carby. There is a spark but to what intensity I do not know. I fitted a new kit in the decompressor but it did not improve. When either the sparkplug or decompressor is removed the starter rope unwinds normally. The exhaust port is clear and with the muffler removed there was no improvement. Fuel is fresh and the LN Carby has been cleaned. Initially, the starter rope broke and I gave the unit in to the shop for a new rope to be installed. In my ignorance as the sump was lying open I poured two spoons of engine oil into the sump and when I first experienced the lockup I turned the unit on to its side and drained it out and wiped it clean.I am thinking of washing it out with kerosene. As there were some holes in the casing behind the carby and up the rise and also some at the side, I fashioned two steel pieces to the contour and brazed it on to cover the holes. This was all done without removing the engine so I insulated the intake,wires and ign module with ceramic fibre (1200'C) All though nothing got burnt by the oxy flame I still feel that the prolonged heat in the area may have affected the ignition module even though I dis see the spark. A multimeter indicates a resistance and continuity. Not being satisfied I thought it best to install a new module. SO, I tried to get the base plate of but lacking equipment I used a socket spanner and hammered on the end of the extension - No luck. Drilled holes on the side of the nut and usec a punch to shift it without result. So out came the oxy to heat the nut and this time success. I still have to work out how to remove the boss and the rest of it so that I can get to the flywheel to remove it. There is one possibility and I cannot see what relationship it would have on the compression, dislodgement of the key in the flywheel. I am considering stripping the motor down but at the end of the day If the problem is still there then what have I achieved. HELP ! HELP ! HELP !
