I am on a road trip from Seattle to San Francisco and having a blast. I just recently had my cylinder head replaced along with the new camshaft and the car was running fantastic. Recently, I am having a difficult time going up hills however.

When going up hills it seems to be struggling. Any thoughts or ideas would be appreciated. Is this just something related to tuning the carburetors?

Is this something serious?

Again, it is just when going up hills. If I have sufficient speed going up hills it is fine but cannot maintain that speed and downshifting that's not necessarily help.

My gut tells me that everything will be fine and I don't have to immediately stop but just need to be sensitive when going uphill's pulling aside if need I'll pull over at times that just makes it more difficult to get started again. I can maintain typically speeds of 40 miles an hour or so going up fairly steep hills but if very steep then I have to slow down even more and put my flashers on.

My gut tells me that everything will be fine and I don't have to immediately stop but just need to be sensitive when going uphill's pulling aside if need be I'll go often times that just makes it more difficult

I just spoke at length to Don Lawrence and he believes as do I that this is likely a result of bad carburetors or bad tuning of carburetors. He says there is no one around that can tune them properly and I likely need brand-new carburetors. Any ideas on a shop along the Oregon or California Northern Coast that might be able to check out my carburetors and tune them properly.

Note that currently the idol is very high which might likely be the result of the carburetors not being tuned properly. Any thoughts are appreciate
 
Well, the obvious answer would be to look at elevation changes. My weber manual states that tuning should be evaluated any time you encounter more than 900' of elevation change.

What kind of carbs are you running?
 
I am sure there could be many contributing factors for the condition but...........

I blamed it on my webers and me not being prepared to re-jet them from their sea level setting while crossing the high altitude mountains from Colorado to California. I could drive 100 mph on the plains between the mountains but it took me hours to drive up each of the never ending mountains under load needing to stop continually. The symptom finally went away after making a high speed decent down a serpentine section of route 50 to Austin, Nevada. It drove fine the rest of the trip to Monterey. I just assumed that the quick back and forth motion cleared something and I believe this was confirmed when I replaced my fuel sender unit (thanks SFDon) in the gas tank and the mesh filter on the bottom of the sender was almost completely clogged.
 
I am loving life. Having a great ride although I must admit that is frustrating going up hills. Another theory is that we got a bad tank of gas. We just re-filled our tank and it is a lot better driving for so much all better. Wish us luck tomorrow. I may try to document our experience for others. Hope all is well

That is really interesting. Where could I look into that? It might be the case for me as well. Thank you. Enjoyed reading about your journey.

You have to remove the sender unit from the top of the gas tank (under the right side trunk floor panel). I cleaned the mesh screen with spray carb cleaner.

If the mesh screen is plugged, a shorter term fix, might be to use compressed air and back flow air through the fuel feed prior to the mechanical pump or at the tank. Compressed air could even take the form of plain, old fashioned, lung power.
