Thanks Brian. I have searched, but haven't found anything that specifically answers my questions. It would be good to talk to a current owner that is running the same engine.Hi Tim Have a scroll through recent threads, I'm sure there was one that touched on this. ?.
Thanks, thats helpful. What carb, cam and compression are you running?I have a big bore Comet and then sometimes its not ie I have a top hat bush for the crankcase if I want to revert to 500 cc I have never altered my timing from 34 deg BTDC or varied from a target of 4deg BTDC valves fully open (the Compression ratios being simillar) I have also run it up on Bens rolling road and the timing is the best
Message sent Charlie thanks.Give me a yell, Tim. I run the "Comet on Steroids" and we met at Stafford about four years back. hardarser(at) outlook.com. Cheers, Charlie.
, Thanks Peter, that's helpful.For what it's worth, I remember Bob Dunn telling me that, for his big-bore Comet engines, you should start experimenting with the ignition timing at around 26 BTDC - and expect to end-up somewhere around 26 to 30 as the sweet-spot.
