I could advice to Change all the Vacuum Hoses if they're Old & Brittle, also a Carburator rebuild is Good Idea if you suspect it is Acting... and those Hitachi Carbs are a True Nightmare, I Swapped a 32/36 Weber Carb on my '85 "BumbleBeast" Years ago and never had a Carb issue so Far, plus gained Low end Torque and Boxer Engine Rumble Noise!

 

Also check the Timin' Belts, and if the initial timing is properly set, maybe your engine needs a Full Tune Up, you know... SparkPlugs, Fuel Filter, etc...

 

Kind Regards.

Fuel filter?  Spark plugs/wires/rotor/cap?

 

Is this the same car that you posted elsewhere as a failed air-suction-valve (ASV)?  Sucking exhaust could be your problem.

Don't swap carbs.

 

First.....change the fuel filter(s) and make sure the timing/spark is good (good plugs, cap, rotor)

 

After that, if you still have hesitation, take the top off the carb and clean out the emulsion tubes, jets, and bottom of the bowl to get grit/gunk out.

 

Reseal/rebuild kit is less than $25.  You don't need to take the carb off the intake, just ake off the top of the carb.  There is one very small cotter pin that holds the choke linkage that's a bit tricky......otherwise it's really easy. 

 

take off the accel pump linkage (note the washer setup) then remove the five screws from the top.  Unclip the wires from the side.  Disconnect teh one that goes to the choke so they won't catch when you flip the top over.

 

Honestly it's super easy.  Takes less than an hour to do a good job.  Will run like a whole new car when done.

Also check exhaust back pressure. If the CAT is plugged, the same thing can happen.

Start with fresh plugs and wires. This is super cheap and super easy. What you described sounds like faulty plug wires. if that doesn't fix it, look to your fuel filters and possibly the pump. Could be something else, but I wouldn't look there until you've checked these things first.

 

My experience says that carb issues will usually be more problematic at idle than 3000RPM+

 

Is this car new to you? Or was this something that developed recently?

It can help that the engine is at operating temp when removing the spark plugs - just be aware of hot engine components and bare skin. The heat helps with the plugs threads release. I use anto sieze grease on the threads on install.

 

I just fixed a low speed , with load miss - it was a 1.0mm plug gap on one plug instead of 0.8mm of the others :)

 

Yours sounds more like fuel filter, fuel line s can crud up inside too with rusty stuff. I have found to blow backwards through open ended lines with compressed air has blown out said crud and fixed my problem

I would agree with the fuel filter first.  

 

Go easy on the compressed air on the lines; they aren't designed to take 120 psi!!  And I would not try the compressed air except as a last resort.  if the sock on the end of the pickup is the problem (or even if corrosion in the lines), then you will blow the sock off and all that floating crud will start heading towards your engine.  Better to drop the tank, blow out the lines and clean the tank if it is that bad.

 

"blow backwards through open ended lines " +1

 

Just change the filter and see what happens, don't worry about the rest.  Always start withe the simple stuff "K.I.S.S".
