Joe-
What is your main jet stack on your DR177 kitted VBB engine? Mine does good until about half throttle then sputters and turning the air screw on the back of the carb doesn't change anything. I think I am running it to fat/rich. Any ideas? |

Mike...
I have a engine in tupperware that was a 125cc p engine that has a dr 177 kit on it for a yr or so = ran great...!!
then I swapped a p200 (215cc) in there and that what I run now till I go for the upgrade this spring (thats the plan anyway)...
I'll check right now and post up what the jetting is / was...
hopefully that will be of use to you since the dr kit 177 is a dr kit 177 but the crank does make a difference so other input will be important to you...???
I think as of this post the carb is a 20/20 si stock carb...
will post up again asap...
time to get oily...!!!
edit:
ok here it is...
small jet = 50
main stack = 160, BE3, 105 (top to bottom) |
