Evs-One Posted August 26, 2009 Report Share Posted August 26, 2009 Pretty new to carbs here, minus Edelbroch 650's :P I figured out that the secondary definitely isn't opening..using the paperclip trick. Diaphragm appears OK, cut down the spring, and still nothing. Any starting points? Thanks! 74 620 truck stock engine. Quote Link to comment
banzai510(hainz) Posted August 26, 2009 Report Share Posted August 26, 2009 rev up the motor and put your hand ove rthe main barrel and see if the 2nd open. Since theyre will be alot of vaccum it should open. Habe you pushed on it with your finger to make sure its not jammed up.? Quote Link to comment
LAYEDOUTB2K Posted August 26, 2009 Report Share Posted August 26, 2009 on my 1200 the electric choke wasnt opening. i put a couple drops of penetrating oil on the shaft and it freed up. Quote Link to comment

It's just not opening when it's supposed to :( on my 1200 the electric choke wasnt opening. i put a couple drops of penetrating oil on the shaft and it freed up. I'll try that! Quote Link to comment
datzenmike Posted August 27, 2009 Report Share Posted August 27, 2009 ...I figured out that the secondary definitely isn't opening..using the paperclip trick. Diaphragm appears OK, cut down the spring, and still nothing.... Wouldn't cutting coils out of the spring stiffen it? Quote Link to comment
