Since I brought my Tiger I have been going through it and correcting all the errors and faults that previous owners have generated .One thing that had me stumped was difficult starting both hot and cold and a miss when I hit the gas suddenly. I thought it was carb related but going completely through the carb revealed no obvious problems . In defeat I handed it over to my old school mechanic friend . Firstly he found out that the coil was only seeing 5 volts or less on starting as some one had wired the starter solenoid incorrectly . The cause of the miss was in the distributor . When the vacuum was high the bottom plate was rocking and opening up the point gap causing the miss .I never would have found it -We installed my spare distributor and all good . As the distributor is original I will rebuild it and reinstall it but thats a job for later .
