No start after warm

[Tikal]

Hey whatcha think would cause this darned ol' oilburner to not wanna crank up after it's been warmed up, driven, and then shut off.
Just started this after I plugged in my TW chip.

I'm gettin' a feelin' it's my HPOP since sometimes if I put it on a hotter tune (i.e. race, or tow) it'll crank right up...

If I don't, it'll crank, run for a second or three at really low idles, then die. Sometimes it'll take 5-6 cranks before it straightens out.

I've got a pretty long list already of orings I need to check and/or change lol
