Took the bike out of the garage thinking about a test run after latest ATD issue.
*smile*Fired her up first kick but, when revving out, she was a nasty bi*ch, backfiring, being lumpy and spitting back through the carb, finally stopping and refusing to start.
I whipped off the timing cover again to check whether the ATD was ok - IT WAS, so had a think.
I remember someone, somewhere, saying that some new springs on the ATD were too strong and the bike wouldn't advance as it should at speed.
Replaced springs with used, original (non-Wassell) types that I had spare. Retimed engine, back to together, fired up 3rd kick (which is normal for mine) and ran and revved out smoothly. She also sounded right (didn't before) - just ran 'cleaner' if you know what I mean. Anyhow, I'm eyeing up a local ride of around 50m to see if she spits out her teeth again.
Just a quick idea here though, I was looking for a 'peg' down the earth brush hole to prevent the maggie from turning on initial offering up and nipping up the ATD. Couldn't find a 5/16 BSF to suit, so thought about a nylon bolt (which I didn't have). In the end, I found an unused nozzle from a tube of sealant. Cut a bit off the end and screwed it into the hole. As it went in, it cut a thread on the outside of the nozzle, and managed to lock up the maggie pretty well (was reluctant to use a metal bolt anyway for fear of damage). Good thing is, it's reusable with the thread, and the timing seems good as well.
