Re: carb spitting gas and boggin out when give gas

is it flooding? mine did that when it was flooding, my choke was/is bad. do you know where your choke is? check and see if its getting stuck on like mine was, its on the left side if your looking at the front of the vehicle.

Re: carb spitting gas and boggin out when give gas

hey its not flooding but when messing with it yesterday noticed the choke wasnt opening up. does anyone know where to get an eletric choke for a roch carb? looked at auto parts stores here and cant find one. but even when i held the choke open it was still running ruff. any ideas?thanks.

Sounds like its time for a rebuild. It also sounds like your floats are sticking.

Re: carb spitting gas and boggin out when give gas

I just pulled mine off an old rochester that someone gave me, he used to work on carbs. I would just go around town and ask a few shops

Re: carb spitting gas and boggin out when give gas

Where is is spitting gas from? If it boggs when you are sitting in your driveway (no load) you probably have a timing issue. I had a similar issue. It could also be that the tension in the spring that holds the secondaries closed is to light. Try holding the secondaries closed and throttling it and see if that fixes your problem. There are two squirters, one in each primary hole, that squirts gas into the bore when you give it gas. Is it maybe one of these splashing against the bore that you call spiting?

From a fellow LT owner congrats on your purchase. What color is your car? Btw, I have the same issue with mine when I floor it.
