It never ends. Just as I get the thing running perfectly, fueling spot on, ignition system producing a spark, it all turns to shit.
Decided to swap 125 main for 122 recently. Did that, but the shit-house Keyster carb rebuild kit's float bowl rubber seal swelled to a huge size and wouldn't fit back in. Won't be buying anything from Keyster again. Managed to stuff it back in, but part of the seal was pinched and weeped a little bit.
Decided to fix that today. Pulled a float bowl rubber out of another carb I had, moved the jet needle from pos#4 to pos#3 (one setting leaner). Put everything back together, now 100% fuel tight. However the bitch doesn't like to start, or idle. With pilot screw set at 1.66666 turns out, it misses at idle very frequently. It's very slow to return to idle when revved. Things improve a lot when the pilot screw is turned out many turns (it's almost falling out), but it's nowhere how it was before (and why should this be screwed out so far?). When opening the throttle it often stalls. What do these symptoms suggest? Surely changing jet needle height one notch shouldn't cause this. Have I mangled the float height? Bent the needle? Grrr.
As GiJoe1313 told me, `if it ain't broke don't fix it'. I am dumbarse.
