Back firing went away when I put on a filter on the PCV valve. Hope that's the right thing to do.

So I had a backfiring issue after replacing my Carter carb to a Weber carb, I tried everything to a point where I even replaced my EGR valve. Then I undid my PCV valve and no more back firing. My question is I put a Small filter on the other side of the PCV valve and that seems to work, is my...

My choke is working again, blown fuse. Any one know where this vacuum line go's I have it capped off right now, it sucks really hard, I think it should be plugged in somewhere.

That's when my problem started when I bolted the new carb on. I'll keep playing with the choke

Thanks good advice. I checked my spark plugs and they look very white like I'm running to lean, any suggestion how to adjust that, could it be my electric choke, it only opens up when I hit the gas then it closes again.

It's working, it was the starter relay, still don't have a cure for my back firing, set my timing and tried every adjustment on my carb but no success.

Hey guys, have a problem. I have some back firing so I'm going through my tuning stages. After doing my timing which is very hard to do when there are no lines to set my timing with, it won't start, nothing, like the battery is totally dead yet I have a full battery. Did I do something by...

Thanks guys for the great suggestions, this will keep me busy for a bid. I'm loving the carb already, the engine has never run as smooth and it's not even set properly.

I will try that.

I capped off a CTO nipple because I had no where to go with that vacuum hose, could that be a problem. I had my timing done last fall, it should be fine.

Don't need a nutter bipass because there is no computer In it.

She staying on now and is filing at 800 rpm, it was a fuel issue, just have a back firing issue to deal with.

An other question, just installed a new Weber carburetor, idles beautiful at 800 rpm. When I drive it cold it back fires every time I push down the clutch. If I let it warm up it back fires when I hit the gas when my clutch is down to get my rpm back down to 800 rpm. When it's hot the rpm...

It's idling better.

I replaced all the hoses and everything is clamped off, no leaks anywhere. It's idling deter but still dies after 10 seconds now.

It's a 32/36. With capping all the vacuum lines, you mean the vacuum ports on the carb, there are only 3.

Just installed a new Weber, starts fine but after 30 seconds it just dies. Rpm still running a little high. I had to cap off a lot of vacuum lines due to no place to plug in. I have a fuel regulator set at 30. Any suggestions.

What does the nutter bypass bypass, it's a 79, no computer and very limited electronics.

Hi guys I have a quick question, I just ordered a new Weber carburetor 32 36 for my cj7 258 4.2L. And I keep hearing this carb only uses one vacuum line, what do I do with all the other lines, is this going to be an issue. I'm just a diy'r and carb's and vacuum lines are my nemesis. Any quick...
