WONT IDLE

[PAUL MANN]

i have fitted some twin 40 dellortoes to my crossflow,it revs ok,drives ok,but it wount idle or if it does it chugs then cuts out,if i adjust the idle on the spindle it will idle but then when i rev it it hiolds onto the revs & returns to idle slowly,just wondered if anyone knew about these dellortoes,i was told they wrwe jetted for a 1600 cross flow,i cant quite afford a rolling road session just yet any help would bu much loved

inlet manifold gasket broke or missing?

carb to manifold gaskets?

brake servo pipe? split?

 

could be a vacuum leak

[vibrating_Cake]

have the carbs been synchronised/balanced?

 

if not i'd get it done, or ask a few on here who know how .

and run some carb cleaner (stuff you put in your petrol tank) through and spray some in the carbs themselves, theres so many nooks and crannies on the dellartos that can get blocked and screw up idle its unbelievable

 

edit lol i read it again, yeh mine were doing that, before balancing the revs came down very slowley. after they just drop down to~1000rpm and stay there.

 

also check for air leaks as above =)
