Hello guys,

i have a 60K carb modified by James at OMI to use with the Kline regulator, and the regulator case kept getting loose on the carb nipple (happend several times before and always fixed with a bit of CA.

anyway i decided to use JB Weld this time to glue it firmly, so i took the regulator apart and carefully glued the plastic case to the nipple with JB, making sure no JB enters the actual nipple, let it dry really well and then re assembled and went flying (mind you i did this several times before, but used CA).

anyway, tried testing it today and the engine kept flooding on me, even when the needles were fully closed !.

this leads me to believe that i might have installed something wrong. maybe the little "arm" inside the regulator (that presses the spring) is on backwards or something ?

could someone snap a pic of his Kline regulator guts for me to be able to make sure i did it right ? if someone knows anything about this problem, any advice is welcome too !

thanks in advance.

OK guys just took it apart again. i forgot to mention that the little plastic nipple that glues on the tank output side was a tad loose, but i dont think that could have caused it.

anyway, the regulator itself is assembled correctly inside, i checked, and there is no option of assembling it wrong.

one thing i did notice was this: when the plastic case is off (and not pressing against the spring) these is no fuel passage, i.e. when you try to blow through the fuel line, no air is going in.

but, when insalling the case (with the rubber seal that had a metal plate in the middle to press aainst the spring) there is some air passage.

can someone else try to blow some air through the fuel line into the Kline and tell me if there is air passing ?

any advice would be appriciated !!

thanks.

OK guys, after 20 minutes with James Oneal on the phone we concluded that for some reason the diaphgram is pressing the inside arm (the one that squeezes the spring) even when it shouldnt (i.e. when no fuel is passing through) - this is why i could blow air through.

anyway, for other who might encounter this, what i did to fix this was slightly bend that arm (so that it protrudes less to the upper side) and this keeps the diaphgram from touching, and no air can be pushed through any more.

its pays off having a mechanical engineer as a father. it was way easier then figuring it out on my own, but for the life of me i still dont see how this part could have bent, i guess i done that by mistake when i took it apart to JB the fuel nipple.

flight report to follow soon, this would be the reat test !
