Mandolezama Posted August 4, 2015 Report Posted August 4, 2015 Was leaking air now I fixed the air leak it held 6psi for over 30 min. Now when I start it for the first time of the day it's floods. I switched my pilot from 25 to 30 I think I may have went to big. Mods are Athena 392 kit, stock carbs with 320 main and now 30 pilot, bills pipes and boysen reeds Sent from my iPhone using Tapatalk Quote

Mandolezama Posted August 4, 2015 Author Report Posted August 4, 2015 It wouldn't idle with the 25 pilot in after I switched to the 30 it would idle good until the next day it would flood Sent from my iPhone using Tapatalk Quote
sheerider1026 Posted August 5, 2015 Report Posted August 5, 2015 Did you readjust the air screws? Readjust idle screws? You had it running decent before correct? (When u were masking an air leak) Quote
Mandolezama Posted August 5, 2015 Author Report Posted August 5, 2015 Before I had to cover the carbs to get it started because it was sucking air from somewhere else and then it would run fine after I got it started. After I fixed the air leak it would run fine just wouldn't idle. I adjusted the air screw but I think I might have forgot to adjust the idle screw. So I will put the 25 pilot back in and adjust the idle screw and see what happens because with the 30 it's getting to much gas causing it to flood Sent from my iPhone using Tapatalk Quote

blowit Posted August 5, 2015 Report Posted August 5, 2015 Few things 1. make sure carb slides are in correctly. cut away on bottom goes towards filters. 2. Make sure they are synced. Usually when you pull carbs, cables get moved around and gets off. 3. You need to use the air screws for pilot level adjust. You can typically adjust about 1 pilot size through the range of air screw adj. This will also help tell you if you are getting close. 4. Most of my engines are on 25-27.5 pilots. Helps keep them cleaned out. Brandon Mull Engineering Quote
Ron Burgandy Posted August 10, 2015 Report Posted August 10, 2015 (edited) Check for crossover choke tube. Mine did the same thing and wouldn't idle. That thing is important Sent from my iPhone using Tapatalk Edited August 10, 2015 by Ron Burgandy Quote
