Well, I drive it a bit yesterday. I had hoped to drive it more, but it was next to impossible to drive. It would not idle, the throttle response was not good, and when I shifted the engine did not idle back, it kept reving.

The only thing I changed was to plug the PCV valve back in to the carb base. Should I just plug that off and run the PCV directly to the intake manifold?

I’m wondering if the rod I made for the throttle is not allowing the linkage to move smoothly. I also wonder if I need a stronger throttle return spring setup.

But just not sure what to try to make this work.

Mike,

I had my throttle stick wide-open on me once. Turned out that my throttle linkage was hanging up on the hydraulic line to my clutch slave cylinder.

You may be having two different problems occurring simultaneously.

I would think that in order for the engine to keep reving, the butterfly must have been physically held open somehow. Closely examine the path of the throttle linkage for obstructions. Consider also the torque effect of the engine shifting in its mounts when checking the linkage for sufficient clearance.

I'm not that knowledgeable on the 250 to offer advice on the PCV. On my 350 Chevy and 1600cc VW engines, it doesn't hurt to vent them to the air while you're working on other issues. Have you tried using carb cleaner or starting fluid to search for any vacuum/air leaks?

I asked some guys locally who I might take it to for some help on this issue. Following one of the recommendations, I have an appointment for next Tuesday to have another set of eyes look at it.

I got a call from Dave at Morley and this is what they found.

The first thing they saw was that the intake was still leaking. So, they fixed that.

Then they found a vacuum leak around the shaft for the secondaries. So much for that carb.

They are looking into my options for a carb and will call me tomorrow.

Good news. How old is that carb? Old VW carbs commonly develop air leaks like that too.

I have no idea the age of that carb. I purchased it from a guy in Iowa.

Morley Performance, where my truck is, has ordered a Holley 390 carb to put on it. Whether or not I will be able to drive it Saturday in the HRH will depend on if that carb gets here in time.

Prayers said and fingers crossed.

I will be interested to learn about the Holley carb; either post here on in your other thread.

I am dissatisfied with my oddball Carter YF.

Well, I got a call yesterday afternoon and they told me Holley called and they do not have the 390 available at this time. So, they were going to see if someone they knew could put bushings around the shaft. If not, we may have to get a different carburetor. The more time goes by with this not fixed the less likely it seems I'll be able to drive it this Saturday.

Kevin,

What are you running for a Carter YF? I have a 2100s and my 235 runs like a dream with that carburetor.

I'm just curious, thanks.
