revs dropping and cutting out :/

Post by spike4073 » 27 Dec 2015 02:43 pm

my 340 cvt has recently developed a new issur.... 8 out of 10 times it starts fine then around five min into driving it (just long enough to get it to a inconveinient place) the revs drop out, it splutters when gas applied and then it cuts out compleatly,
upon trying to start it up again it either refuses to fire up or sometimes it does but revs go and it cuts out again after a few seconds :s

ive adjusted the carb so it idles a lil high.... this fixed it for a while altho it was annoying because it was idleing too high to change from drive to reverse but it worked as a get home fix

anyway, its gotten worse now i cant get it to fire up and stay running ... most of the time now it wont fire up at all,,,

ive checked the idle solenoid (working fine)

im thinking plugs?.... not had them out yet as ive missplaced my plug spanner

any ideas??

all input greatly appreciated
thanks

Sounds similar to what my Golf was doing, took the pierburg carb off and replaced it for a weber and it was fine.

Could be an air leak leaning out the mixture too much as it warms up.

Rubbing a bit of glass-paper around inside the dizzy cap could help a lot.

i think ive figured it out

took off dizzy cap to find that the centre contact (spring loaded thingy) is missing and the rotor arm looks like its been through a blender :/
