Any rev up is fuel starvation.
More like "common sense" starvation.
When I emptied the tank of just under 1 gallon of fuel to inspect the petcock I noticed that the main "on" fuel tube was very tall... taller than the amount of gas in the tank... (I can hear the "dumb-ass" comments, people!). That solved the stalling (non) issue.
Anyway, installed the new main (160) and pilot (48) and I'm still getting that choppy response at 1/16 - 1/8 twist. I mean just right at the few mm turn of the throttle through each gear. After that it takes off. Turning the AS a smidgen in either direction after 1.5 turns makes it worse.
I think its time to try a different pilot. Any suggestion on whether to go up or down in size? I know RB suggested gettin' 'em all to have a complete arsenal. Is there a good place to get them quick and cheap online?
Thanks!
P.S.
Inda, reading your excellent jetting guide... you mentioned sputtering can be fixed by lowering the needle clip but that was for 1/4 to 1/2 throttle. Think I should give it a shot?
