#yiv1261382333 P {margin-top:0;margin-bottom:0;}Hi everyone. This is my fi=
rst time posting a question. I've got a 1965 Triumph 2000 Mk1 Saloon. The e=
ngine is basically a GT6 2 liter with dual Stromberg CD150 carbs. I have a =
starting issue and I'd like to tap into the wisdom of this group. When I fi=
rst go to start the car, I give it a little choke, pump the accelerator onc=
e or twice and leave it at about half throttle, and turn the key. The car a=
lways starts right up, even if it's been sitting for a month. But if I pull=
it out into the driveway, and turn it off (or stall it =F0=9F=98=89), then=
try to restart it, it struggles. It cranks and cranks with the RPMs increa=
sing like it's thinking about starting, and sometimes it does, but others, =
it takes several cycles of that before it starts. The warmer the engine, th=
e harder it is to restart. If I let it cool for say a half hour, it starts =
right up again. The carbs were rebuilt about a year ago (this happened befo=
re and after the rebuild). I've replaced the mechanical fuel pump with an e=
lectric one thinking it might be a weak fuel pump, but that didn't solve it=
. I improved my grounding to ensure I wasn't stealing coil voltage for the =
starter, and I even replaced the starter with a high-torque version to get =
a higher spin rate. None of this helped. I thought vapor lock might be the =
issue (I also installed a head shield for the carbs), but it happens when i=
t's cold too. The only thing left I can think of is that the carbs are floo=
ding. But when I rebuilt them, I was careful to set the float height. Befor=
e I pull the carbs to check/adjust, does anyone have any suggestions on wha=
t might be causing this?
