Just sent a Xmas dinner reminder by email...menu and payment details attached. Not long now!

I used to use Tizer for sticky or rusted studs. Could never afford Lucozade.

Further to my earlier post, the check on crank wear is done with an adaptor on a dial micrometer which allows one to both pump and suck air through the plug hole to measure the play. I can't remember the tolerances offhand, but they are in the manual. To look after your crank, first use a good quality oil, making sure, unless the engine has oil injection, that it is suitable for premix, as not all twostroke oils are now. Secondly, make sure that your premixing is precise, as too much oil could be worse than too little. An excess of oil will form little ramps of oil in front of the balls or rollers, causing them to scuff, and increasing the wear. Never add 'a bit more for luck'. And thirdly, warm the engine up properly to avoid 'cold seizures'. (my first reply was using my tablet, which kept flickering. Don' know if it's a tablet or forum problem). R.

It's possible to check for crank wear using a dial micrometer to measure the backlash. I know that Rod at Volair has the tools.
