GLCraig Posted July 14, 2005 Share Posted July 14, 2005 There should be a 0 (zero) mark, that will be top dead center. Link to comment Share on other sites More sharing options...

86subaru Posted July 14, 2005 Author Share Posted July 14, 2005 set top dead center, set timming to .8 , major back firing , surging , so i bumped up timming to .12 , alittle less backing firing , if i really get on the gas is when it back fires , what should i look at next ?

MorganM Posted July 14, 2005 Share Posted July 14, 2005 The three hash marks on your flywheel are for aligning (timing) the camshaft in relation to the crankshaft. The degrees marked on the flywheel are for aligning (timing) the distributor to the camshaft + crankshaft + piston = ignition timing. Thats why ignition timing is so hard to get right What was the situation prior to this problem with the backfireing and poor running? Was the dist. pulled, reinstalled, and now this issue?

86subaru Posted July 14, 2005 Author Share Posted July 14, 2005 the weber was not hooked up at all, and the vacuum lines were crossed , oil was going into the weber, , but it was running fine , i decided to change coils and go with a acell coil and this is how it all started Link to comment Share on other sites More sharing options...
