Engine & Transmission > five speed one piece drifeshaft????? (14 replies - 9162 views)

Call it 90-95% certain.  My car has a 4-speed, and where 5-speeds are concerned, all I've seen is photos and line drawings.  However, it's good engineering practice ...   07-28-2006 07:00 pm

Engine & Transmission > five speed one piece drifeshaft????? (14 replies - 9162 views)

Was waiting for someone to comment who's actually done this themself, but I guess they're all busy elsewhere.  As I understand things, most aftermarket one-piece driveshafts for ...   07-28-2006 05:52 pm

Ignition > Starter Motor Problem (3 replies - 6023 views)

Ignition > Ignition (5 replies - 6517 views)

Carburetors > Carburation (6 replies - 8353 views)

IMHO the most likely possibilities are: Fuel pressure at carburetors is too high (normal is 2.5 psi, upper limit is 3.0 psi, IIRC). Incorrect reassembly of the ...   06-26-2006 01:53 am
