The Stovebolt Site Forums The Shop Area Engine Shop Holley/Weber Problems

Hello All, Last night I installed my just purchased Holley 5200 from Langdon's Stovebolt. I can't get it to idle properly or run worth a s**t.It has no power and an excessive amount of play on the lower throttle plate shaft.Have any of you had any troubles?
Thanks John

hello John; I would give Tom a call at Langdon's,
when I installed the Holley-Weber on my 216 he gave me some good advice,he realey knows what he is doing

I had all kinds of troubles getting my 2x Holley Webers to run on my Offy intake. It seemed like a vacuum issue but I couldn't find it. I finally traced the problem to the gasket between the carb and adaptor. The gasket just wasn't cut right and it was leaking in several places. I made a new gasket to fit and she runs like a top. As someone said, call Tom - he's the master on these carbs.

Are you running a single carb? If so, you may want to talk to Tom. He told me that one carb wasn't enough for that my engine. He talked me out of going back to my stock intake. We are talking about the progressive 2bbl carb used on the Pinto; right?

John I am sure that Tom will take care of any issues you have with any of his products. He is a stand up guy that is willing to help anyone with problems that come up.

Having used both H/W and C/W carbs from Tom Langdons Stovebolt Engine Co. (586) 739-9601 I found that you have to be a little careful when you bolt the carb to the adaptor. If you try to force the fit you will possibly have leaks. I found that if you drop the four bolts with a small washer pointing DOWN in the elongated holes in the adaptor,then coming up from the bottom, slide on the 4 hole gasket and set this assembly on the inverted carb. You may have to wiggle it around to get everything to seat properly. The key is to get the entire assembly together so that it is a LOOSE fit before you spin on the nuts evenly.

The H/W is a rebuilt carb while the C/W's are new. If you're unhappy with the carb condition I'm sure Tom will bend over backwards to correct the situation. A worn throttle shaft is not something he would expect you to accept. However, I would go through the bolt-up sequence again and see if that doesn't correct the problem. All three of my carbs from him were awesome right out of the box. Hope this helps.

Thanks Dave. I did put all the bolts in just as you said, I also checked the base for leaks with propane just in case I had a leak.I'm just going to wait until Monday and try and get a hold of Tom.Thanks John

John, when you get a hold of Tom you might ask about a "new" not rebuilt carb. A friend of mine mentioned that he got a new one for a paltry ten additional bucks.

Worn throttle shafts will leak enough air so that you'll never be able to get a stable idle air setting.....a problem I found with most rebuilt 50 year old original carbs. I hope this doesn't turn you off on the H/W or C/W carbs....I would put them at the top of the list for things you could do to improve engine and drivability on our old trucks at a reasonable cost.

Like others have said give Tom a call and send it back if it has loose throttle shafts, you've got 30 days to return. The Holley Weber 32/36's are rebuilt, so you don't know what jets they have, sometimes they are missing. If you're running a 235 you kneed a minimum of a 60 or a 65 idle jet, just to get it to idle within 1+1/2 to 2 turns out. Check it before you send back, its the one on the outside on the choke side. There's more but if the shafts are bad get another. When you get the next one, take it apart and write down all the jet numbers, they take weber jets and you can get online, cheapest is from Carbs Unlimited. Good luck. Oh and why you are at it throw away Toms little individual metal pieces that hold the throttle shafts and make a proper horse shoe shaped replacemet that won't flex.

I talked to Tom today and he is shipping out a replacement N/C. Excellent people to deal with!!John
