Carbed 88 problem

[denguy]

Needed a head gasket. Sent the head in for a rebuild. Put everything back together and now it idles nicely down the street but if you try to speed up it dies. We marked the dizzy before we pulled it. The car was running OK before we replaced a blown head gasket. Would appreciate any ideas on this.
thanks

Could you have possibly crossed a couple of plug wires? In ccw rotation starting at the top left the wires should be 1-3-4-2. May not be it but always worth checking the simple stuff first. Also when was the last time the fuel filter was changed? Or maybe a collapsing hose or bad fuel pump? Just a few ideas to check out.

Thanks for the comeback. New plugwires are ok. Pulled fuel line off the carb and started engine, plenty of gas came out. It idles sweetly but stumbles and dies when you step on the gas.

Im gonna say a vacuum problem. Have you went through and checked the vaccum lines?

[denguy]

Going to do that somemore.
thanks

Check to make sure you have vacuum on the port that's located on the back of the carb, towards the left, near the top. I had the same problem and hooking vacuum back to that fixed my issues.

spray carb clean at the base of the carb at idle to check for vac leaks, eleminate the carb base gasket and then move on to olcal vaccum hoses.

sorry.......olcal ?

Any chance that after the head replacement that you got your base timing is off?

^ X2... may be off by a tooth. I've had it happen both ways depending on which way its off you can have a decent idle and falls on face when given gas. Or in the case of my Miata where the crank keyway for the lower timing cog is very worn (base timing is always off) it is very rough till you get past about 4.5k, then it absolutely screams after that.

olcal = local i didn't spell check...
