Jboss112 Posted August 27, 2017 Author Report Share Posted August 27, 2017 Yes it is only way I knew to explain the problem Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted August 28, 2017 Report Share Posted August 28, 2017 Pressure test, compression test, if those check out move on to electrical testing. It could be something as simple as you put the carbs back together wrong and mixed up parts between the two or are missing something Quote Link to comment Share on other sites More sharing options...
hotrod9193 Posted August 28, 2017 Report Share Posted August 28, 2017 Also pull your petcock out and make sure it's clean and fuel flows good from it. I have seen guys spend a lot of time chasing down an issue and the whole time there fuel wasn't getting to the carb fast enough Quote Link to comment Share on other sites More sharing options...
Jboss112 Posted August 28, 2017 Author Report Share Posted August 28, 2017 I took one carb apart at a time and put it back together before I took the other one apart. So can't be mixed up. Took picks of everything before I took it apart, just so I knew it was going back together properly but I will run the tests then get back Quote Link to comment Share on other sites More sharing options...
