KAMIKAZE Posted September 20, 2014 Report Posted September 20, 2014 Redline 421 serval 33pwk carbs Pods Vf4s Shearer sb/sf 150 psi on both cylinders 48 pilots 170 mains Sea level in Australia Basically the plug on the right cylinder is coming out wet still and they appear really white (not sure if the photos show this that well) Its also gutless, a stock shee with pipes is keeping up when I'm doing runs to check plugs I only have enough space to do this in 4th From all the reading I've done 170 mains seems big? And I have limited carb experience so not sure what would cause wet plug Any help will be great Thanks Quote
KAMIKAZE Posted September 20, 2014 Author Report Posted September 20, 2014 This is them chopped Quote
sprinklerman Posted September 20, 2014 Report Posted September 20, 2014 Carb issue or ignition issue. Passes leak down test? Quote
KAMIKAZE Posted September 20, 2014 Author Report Posted September 20, 2014 Same cylinder causes issue with leads swapped Do you think I should up jet sizes ? Any suggestions for carb? Quote
Finch Posted September 20, 2014 Report Posted September 20, 2014 passed a leak down before i pulled intakes and shipped it. wish i know about pwks to help ya more. how many passes are on those plugs ya chopped? Quote
KAMIKAZE Posted September 20, 2014 Author Report Posted September 20, 2014 Put them in after I warmed it up and did 2 runs Hanging to get it running right ay Quote
sprinklerman Posted September 20, 2014 Report Posted September 20, 2014 That one side looks like it's dumping fuel. What's the history of the carbs? Known good? Float level right? Needle and seat clean and working properly? Quote
KAMIKAZE Posted September 20, 2014 Author Report Posted September 20, 2014 I Bought the carbs from 2strokelove. They had been running sweet on my old set up with no issues until the last 2 rides it was doing this I guess I'll strip them and clean everything Quote
sleeper06 Posted September 20, 2014 Report Posted September 20, 2014 Def do a leak down for peice of mind , do your plug boots ohm out correctly, check the carbs good Quote
sleeper06 Posted September 20, 2014 Report Posted September 20, 2014 Also I have found 33 pwks to like a dek needle in some situations depending on porting Quote
locogato11283 Posted September 20, 2014 Report Posted September 20, 2014 48/170 is probably on the lean side. That's close to what we run at 1,000' above sea level. I'd put a 50 or 52 pilot in and a 172 or 175 main and run it again. You're better off being a little rich than too lean. Also, are the carbs synced? Quote
KAMIKAZE Posted September 21, 2014 Author Report Posted September 21, 2014 Will do a leakdowm today and see how we go They have cell needles and are synced Will get some bigger jets and keep going Quote
KAMIKAZE Posted September 22, 2014 Author Report Posted September 22, 2014 (edited) Stripped both carbs, cleaned and inspected everything this is what I found Like a sticky gunk on the needle, cleaned it off and that solved the wet plug issue Although it runs a lot nicer its still way down on power would this be from the jetting? 48/170 is the biggest I have currently Edited September 22, 2014 by KAMIKAZE Quote
KAMIKAZE Posted September 22, 2014 Author Report Posted September 22, 2014 On closer inspection on the right side(carb that was causing the issue) the pipe is about half the temp of the left pipe So I take it there is still another issue Quote
