Dashpot adjustment for Rochester 2gc
Hotrodjohn71 replied to Hotrodjohn71's topic in Pontiac General Discussion/Questions
Thank you. I am incredibly thankful for your time and regard for my question. -
Hotrodjohn71 started following Hello , Dashpot adjustment for Rochester 2gc , 68 Firebird brake booster question and 2 others

Does anyone happen to have a 1965 shop manual that can share the vacuum dashpot adjustment for our Rochester 2GC carburetor? I've searched online but cannot seem to find an instruction sheet pertaining to our particular Rochester. Ours only has one idle speed screw, (on the driver's side). The tech sheets that I find show a high-speed idle screw which ours does not have. So I don't know if that information applies to ours.

68 Firebird brake booster question
Hotrodjohn71 replied to Hotrodjohn71's topic in Pontiac General Discussion/Questions
Thank you for all of your help. I have solved this breaking issue by installing a 9-in Delco Moraine brake booster. I have a good and high pedal now that is not grabby or extremely sensitive. -
68 Firebird brake booster question
Hotrodjohn71 replied to Hotrodjohn71's topic in Pontiac General Discussion/Questions
Thanks for the advice. I have an 8" delco style booster on the way. I will also recheck if the drums were new or turned. I am pretty sure they are new. But I will find out. -
68 Firebird brake booster question
Hotrodjohn71 replied to Hotrodjohn71's topic in Pontiac General Discussion/Questions
I will have to do a bit more research, but according to this manual, for 67, the cars without DB had 1" bore master cylinder. I did an experiment the other day and unhooked and plugged the vacuum line to the booster and it was a great pedal, high and firm. But just lacking assist. Hard to push. -
68 Firebird brake booster question
Hotrodjohn71 replied to Hotrodjohn71's topic in Pontiac General Discussion/Questions
Hi Kiwi, all the brake drum assemblies are clean, dry new and adjusted correctly. All wheels are adjusted so they will spin about half way around. On this 67 Firebird with power drums, they did not actually have a proportioning valve. They do have a distribution block which is just a 4 way junction block with a switch to the BRAKE warning light which only serves to show a differential between the front brake circuit and rear. -
68 Firebird brake booster question
Hotrodjohn71 replied to Hotrodjohn71's topic in Pontiac General Discussion/Questions
Hi Kiwi, if I do a panic stop, the fronts will lock up, but I think all the wheels lock up as well. Our m/c is a 1" bore which is correct for power (all drum). Manual (all drum) are 7/8" on the 1967 Firebird. For the power drum/disc cars, it's a 1 1/8" bore m/c. -
68 Firebird brake booster question
Hotrodjohn71 replied to Hotrodjohn71's topic in Pontiac General Discussion/Questions
Thank you Fitzy. You bring up a point that is very interesting. I actually don't know anything about this booster as it came on the car from a seller out of state. I now have a new question after researching this for a while. I see listed for a 1967 Pontiac Firebird (4) different brake boosters with seemingly no differentiation I can find (which really makes me wonder if my booster is correct for my application). One is 11" single diaphragm, one 11" dual diaphragm, one is 9" single diaphragm, and one 9" dual diaphragm - all being listed for 67 firebird . -
1967-1968 Steering Wheel

Hi, 64 kiwi boni, Thank you. I know how to restore them but I need one. The one in the photo is not mine, but one I found on the internet. I think that these were undesirable style wheels and they just got thrown away back in the day. I highly doubt this specific one was ever reproduced. If it was, I would be glad. Thank you for your input -
