Default Somethin' weird.....

HI Joel

Unless the clutch linkage is rubbing on or pressing on something relevant to the fuel or the dizzy I can't figrue that one out.

Let's get back to basic.....

Engine will start

engine will idle in neutral

engine idles smoothly at 450 to 475 rpm......

will engine accelarate and rev up when you manually open up the gas by moving the carb linkage near the carb...... and settle back down when released.

now leaving the truck in neutral will the engine accellarate as above when pressign the gas pedal.

Have you checked the vacuum advance to see if the dizzy twists / moves when you manually accelarate the engine....

do you have a reading from a vacuum gauge...for idle..... how steady is the needle.

any rubble in the exhaust at idle.

Now time to crawl underneath the beast.....

have someone press the clutch from above......

is anything rubbing on the clutch linkage

Now try again........ live dangerously......

engine running.... in neutral..... have someone depress the clutch.....

same.... have someone engage in first gear and slowly release the clutch while looking underneath......

Unless something is binding in the clutch pack.... throwout bearing....

Is the tranny easy to shift in all four gears...... including reverse.....

Wait a minute...... could you clutch linkage be activating the brake pedal when you press down on the clutch pedal.......

Man I wish you were around the corner so I could drop by.....


Check these things out and get back to us...

Never seen that mod before.....must admit it makes a lot of sense.
