Hey guys

was wondering if you guys ever pull out your carbies regularly to replace the o ring seals on the mixture screws. I am currently suspecting that my mixture screws are unscrewing on their own ... and suspect that i damaged the seals when i was cleaning my engine i used engine degreaser (the automotive trade cans) and since at the time i did not have access to a air compressor i had to resort to leaving it in the sun to dry along with my chassis. Whats your thoughts?
