wallo Posted August 19, 2015 Report Share Posted August 19, 2015 If you have a spark and you don't get a bang or pop after putting petrol directly into the barrel any ideas what this means, is the timing totally out? Quote Link to comment Share on other sites More sharing options...
crazybond700 Posted August 19, 2015 Report Share Posted August 19, 2015 (edited) In order to get a boom, you will need a mixture, not gas. So you will need a carb. Also make sure you dont float your entire crankcase with fuel. Edited August 19, 2015 by crazybond700 Quote Link to comment Share on other sites More sharing options...

jon v8 Posted August 19, 2015 Report Share Posted August 19, 2015 Whats the history ? A spark somewhere around TDC on the firing stroke ought to make something go bang with a little fuel down the plug hole. A cam and spark timing check is in order. Got very patchy interweb at the mo, at a farm in the Peak district, I think the sheep are chewing the phone lines.... Quote Link to comment Share on other sites More sharing options...
