86 civic DX HB 5spd carbed w/1.5 EW1 engine

I can't be too much help in this department since I've never modified a stock Honda carburetor. My carb knowledge is limited to Weber, Holley, Rochester, Carter and Edelbrock, and I'm using a slightly modified fuel injection system on my CRX. Maybe someone else will chime in, but RPR is probably your best bet.

Good job on the intake manifold, I ported my whole head and intake manifold using a Dremel and about 5 different attachments. The only thing that has me concerned about your modification is the dowel, being a wood worker I know how much wood shrinks and expands so there is potential for the dowel to slip and/or burn up. Wood will also soak up fuel and will deteriorate over time, JB-Weld might be a better way to plug up the hole.

I like your candor, we have come a long way by swapping not only the head but the whole CRX longblock. Resolved ignition problem and given me some things to consider for the future. I will take your advice and look into RPR for carb solutions.
Thanks lxndr

the saga continues;
I thought about your comment regarding wood in IM so I took the carb off and sure enough the wooden dowel was loose in the CVCC port. Took your suggestion and cut about 0.75" off the dowel and filled the gap with JB Weld.
Found a 2 barrel Accord carb at wrecking yard and put in a rebuild kit. Installed carb, devaced the engine, and installed a 2" exhaust pipe system using theory from my slotted wave guide engineering days.(system passes gas OK, but too noisey for my retirement community)
So all-in-all, this forum has led me down the garden path with good results and a 3G civic that will be my transportation hedge against $3.00 gas.
THANK YOU one and all for the help
