40hp produces little power at wide open throttle

[vwbusman66]

Hi all, about 6 years ago, I purchased a 1958 VW panel from a certain thesamba user (whose name I will gladly inform you of you direct message me, as he is still "building" and selling these "excellent" vehicles) (skip to bottom if reading is not your forte) who did an "outstanding" job "building" this bus. It was found in Arkansas and he put in an IRS, lowered it, claimed to have put a ball joint front end in it (he lied, by the way), put a "good" motor in it, and "rewired" it. I received the bus on a trailer about 5 years ago, where upon attempting to start it, was greeted with absolutely nothing. After some investigation, I noticed that the filter was full of sediment and pulled the tank shortly thereafter. The tank was about half full of dirt and gravel. I did the shake with clean gravel method for about 7 hours and still poured sediment out. I sent it to a gas tank shop to have it cleaned, and reinstalled the tank. After it was hooked up, the bus now started. I quickly took it out for a quick drive and noticed at full throttle, the bus would do about 35 in fourth, not under load or anything. It wasn't loud or screaming either. I sent it to a friend and about $1500 and 30-40 hours of labor later, I had a decently set- up 58- panel. It was now correctly rewired after the previous owner's "great" wiring job and I put on some correct part that were supposedly installed but weren't. Now to the present- I have the engine on the bench and have long since replaced that engine and the bus drives great. I was looking at it and noticed the arm that is on the side of the carb (pict-28-1) pump is hitting the side of the "correctly" installed alternator. I am wondering if this could be the issue to this long and troubled tale. Also, what header would you recommend for this engine to put a stinger on it? Thanks so much, James

If you don't have an aluminum spacer between the carb & intake manifold that might do the trick

Okay, as predicted the general consensus says that I am in need of the spacer used with alternator conversions. Thanks guys, James

Also, what carb will fit this as I need one with an arm on it for throttle return. Thanks, James

All 28 PICT's and the early 30 PICT 1's had the return spring on the cable. The later 30 PICT 1's the 30 PICT 2 and 3 have the arm on the carburetor.
