Compression test gave the following -
185,182 ,185,183 for cyls 1,2,3,4, so I assume all is ok there ?
Took off carb, cleaned jets, cleaned plug, took of dizzy cap , and ensured all connections were ok, reassembled.....and......
it now seems ok...
When I get chance , I'll retest mixtures with colortune ...
cheers
