Holley/Demon Carb stumble

jetted it up yesterday. 82/90. thought it would be too much. but after adj the idle mixture screws, it ran the same.
snap the throttle in neutral and no sign of stumble. Put it in gear (3d) and wack the throttle no stumble. Stall a little and wack.......stumble.
Take it out on the road, stumbles from idle, stumbles at 2200 rpm launch.

Got my "Demon Squirters in the mail today................Fancy Demon package.........STANDARD HOLLEY SQUIRTER.......:wtf:

Called Holley yesterday to see if they had a 750 main body that i could put on My 850 Demon. Gave him the part # of my carb.
He said point blank "That's a Barry Grant carb and i would have no idea if it would fit". That was the end of the subject. he had no other opinion about it.:realcrazy:

So round 2 i get a main body for my Holley carb....... NOPE!!! they only make them for 650 and up. My carb is a List 6776(600) and they only make them for 650 List 6777 and up.

Ordered a carb kit for the 600 DP
While try the, so called" Demon squirters" in it first, but i don't have much hope.



Time to sell that turd and buy the carb skrews has for sale here.

You'll be miles ahead.
