Why.....

[Martin64]

...would a truck only cut-out (like you're trying to take off too fast before it's warmed up), coming from a dead stop and only while making a left turn? Stock 230, 3 speed on the column. This started a couple/few days ago. Neither up-hill or downhill right turns from a stop do it. It only does it while making left turns from a stop. The truck is warm, the choke is off.

Well, the manifold and carb are on that side...that may be a good starting point. I suspect a float problem.

[Martin64]

Which side of the carb is the float hinged?

[Sinister-65]

is coil mounted securely ?

[Martin64]

Ignition side of the truck is fine. That's what I suspected 1st but everything there is fine. I was suspecting fuel after the ignition stuff check out ok. Especially after driving around my neighborhood for a few laps (in every which direction I could), that's when I nailed it down that it was just on left turns from a stop. "Rolling" left turns don't matter because I'm off the throttle and have enough wheel speed that I roll right through them.

I'm not familiar with what carb you have or where it's hinged, but I did experience a similar problem years ago on a small block 4 barrel Chevy. I don't remember if the floats were set too high or were sticking with the fuel sloshing in one direction. Hard left turns caused gas in the float bowl to spill over into the manifold and the engine bogged almost to the point of stalling. No other problems driving, stopping or turning right, but it was sure embarrasing making hard left turns.

[Martin64]

That's what it's doing Mark.

[ol Curt]

With the manifold on one side of the six rather than on top, orientation of the carb (if four barrel) or a float sticking if it is a 1 or 2bbl can make a difference.

Which carb do you have?

[62gmc910]

Does it bogg like it over fuels ,like the choke is pulled
maybe float level but i doubt it unless hard turn and acceleration




or cut out like it has no fuel
maybe float but again doubt it
maybe a vacuum leak do you have power brakes? engine torque + side thrust may open a line???

I think it's just one of the downfalls of the motor. The thing is just such a tire smokin, front end liftin powerhouse, its a little sluggish on left turns. It's a trade off.

I would bet the float needs to be set. I race dirtbikes and when the float is incorrect, you need to lean the bike to one side for it to start. Pull the carb and set the float and you should be good.

[Martin64]

After pulling the carb and checking the float heights, the only thing I did was tighten up the float around the pin where it hinges. It looked as though there may have been enough slop for it to possibly hit the carb bowl if it shifted. I took it for a test drive after adjusting the carb and it ran fine.

The carb is a single barrel Rochester

[markeb01]

Outstanding. Glad you could fix it without spending money.

[cliffy]

left turn signal shortin out? (snicker)

[Martin64]

Well, I'm back to square one with this. Whatever I did to fix it the 1st time has come un-done. It started cutting out again about 2 weeks ago but I worked 2 weeks straight and didn't get a chance to check it out until today. I tore it down as far as it would go and found nothing. The hinge for the float is still good and tight (it works but no "slop"). I need to get this wrapped up tomorrow morning so I can head back over to El Centro for the week and not sure what I need to be looking for next.....maybe a new carb?

[protrash64]

This may be dumb, but.....does it happen when low on gas?? I'm not familiar with the stock gas tank and the pick-up tube.

[Martin64]

No, it's happens with a full tank too.

I'm really at a loss as to which direction to go now. I'm going to do some more searches online and see if I can trip across anything earth shattering.

[Martin64]

Well it turned out to be the carb. I bought a complete 250 cu in motor with a synchronized 1st gear transmission a couple months back and the carb that came on that motor did the trick. Now it accelerates alot stronger as well as through the turns.
