ouch that sucks big time. get ahold of bronson on here i know he has dealt with thesze beforei just installed the power bowl today and now my quad wont start, it will turn over once but wont stay running, it also backfired through the carb and made my intake pop off.
yeah don't take anything apart... do exactly what voodoo says and just rotate the carb to access the bottom.For pilot I'd start with 50 and maybe go as hi as 54. Without powerpump I use 45. When I was using powerpump I gave up around 48 on the pilot. I tossed it to the side and have not used it since. I was kinda waiting to see if Bronson ever got his to work right and it looks like he did and likes it a lot so I may give it another try. I think its a must that you use this with Jd-Jetting. Depending an your elevation it may alter from my set-up which is Blue needle 3rd clip, 185 main jet,1 1/2 turn on fuel mix screw. This is set for temp 70-80F. at sea level. If its hotter use red needle,higher then drop down on main jet. Here's some setting that should get you close.
Elevation: 0-500 185main
I have not been higher than 4000ft elevation. I left 500ft between each setting because you can adjust fuel screw to get you set. Make sure not to accede more than 3 turns out because you have a good chance it will vibrate loose and fall out beyond that. If you have not already installed a fuel mix screw, you'll want to get that to. Here is a new one made by R&D http://www.r1dean.com/cart/index.php?main_...;products_id=48
Little tip if your only making Jet changes. Loosen the clamp in front of the carb and leave the back connected to the air filter boot, then pop up the air filter boot from its seated position and rotate it and it will give you easy access to the bottom carb plug without having to completely remove the tank and all the plastic.
