i do trim mine up a little when i flip it but its been consistant at starting cold Hot however I need to flip it more chole off i seem to get in trouble when i flip it with choke on. if this dont pop after the 3rd or 4th flip chole on i kill the choke kill the ignition and open the throttle wide open no choke and flip it 4 times then i turn tthe ignition on and reduce the throttle to just off idle and flip it it ussually fires right off after that. the other thing i noticed is after it pops and i open the choke and flip it it takes 2 or 3 theen it pops again and 2 more flips before it runs but like you said i think it needs a tad more throttle to start faster ill be trying that tomorrow
