| | This lucky...... A bolt from the air filter went down the carb wedged t' throttle open to valve bounce. Played with the throttle linkage and she free'd off and felt smooth (didnt know what was wrong at this point). Started up and drove 30 yards with a nasty knocking/tapping pulled over, then it stopped. Job done. Anyway after further investigation the bolt was sat in the cyl head and the washer had gone in and been blown out the exhaust. All compressions tested ok and theres no damage to the head or pistons bores or valve seats from a quick glance, all it did was close the gap up in the plug. :-D
I will have a good look on my lunch break.
Any way im off to do the lottery.

All of the above happened on the way to work in the jago

Very Lucky escape I reckon

You are supposed to put a petrol / air mixture through that bit, not bolts and washers, dear. - Close call - put me some numbers on the lottery, willya?

very lucky we had the tip of a spark plug fail early this year and it took a valve seat on its way out!
