Ok, I have been having a bucking problem when going forward. Only when in gear and on the gas, when off throttle it seems to be fine. So today, I cleaned off the engine and backed it out to the street and put it in a forward gear and I can't go. Like someone has the brakes on or something, you can feel it want to go, but negative. I put it in neutral and try to push with no luck either, I can push it backwards in neutral but not forward. If I clutch I still can't go forward while pushing, only backwards. Feels like the brake is on or the tranny has gone south. Clutch feels fine, tranny works in reverse, gears move thru and feel fine, but no forward....any ideas? My new money pit!!!
