Exactly my issue. It starts fine from dead cold, but stalls after 15 seconds. runs like poo for the next five minutes. Temp of the carb base drops about 8 degrees C from ambient to just a few above freezing. preheat, now, isn't doing much work on the manifold to keep it warm with the newer exhaust. Later when the oil temp comes up, it runs fine. must make more heat... electrically. -- -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: If privacy is outlawed, only outlaws will have privacy. -- Philip Zimmermann iEYEARECAAYFAk7foi0ACgkQlZadkQh/RmHGPQCglSNzf7Yz7AgtF7UUniu334QR 5SkAoJOuMxvnL02lG0GBQweC4aB0AQHg =RIIW -----END PGP SIGNATURE----- |

The preheater tubes even when connected to a proper exhaust would not even start to get warm after 15sec. I have not this whole thread saved and cant remember your exact carb. It sounds like a typical auto choke issue. Have you checked setting/freedom of movement and function of the heater element working on the bi-metal spring? Also, have you checked the base setting of the butterfly itself? How about intake leaks? Gaskets, bent flanges etc. J. -- P.J.Berg --- Posted via news://freenews.netfront.net/ - Complaints to --- |

I should have added he With the engine off(It is stalled and won't run anyways), it takes a while for the heat soak from the heads to travel all the way up to the carb. I spent a few very very cold moments sitting stationary in my -56 in 15-20C below freezing as a youngster.. J. > > > Exactly my issue.

Gaskets, bent flanges etc. This is the kicker, the choke is working fine. Carb is a Solex (actually made by/for Kafer) 34 PICT/3 on a 1600cc dual port. Manifold isn't stock, but the same type just done in aluminum: http://www.cbperformance.com/catalog.asp?ProductID=526 I swapped the exhaust a few weeks ago. The car didn't have the problem before the exhaust swap, but temperatures here did just drop, too. The engine starts wonderfully from dead cold only to just stall 15-20 seconds later and from there on it runs like poo until the oil temp comes up. By 'running like poo', I'll define that as if it's running on three cylinders with horrendous bog. plugs are fresh. It doesn't appear to be ignition as I've pulled plug wires while it's doing this and each I pull makes the engine run slower and even more out-of-balance. So it's not ignition. I'm convinced I have an intense wall wetting problem I can cure with a warmer intake manifold. Again, it runs fine when warm. I only say 'fine' cause I'm sick of the lame aircooled.net SVDA distro I've had for the past 5 years and I'm dropping in a Mallory Unilite series 47 from another motor I'm not using so I can finally tune it to a proper curve. I will check (again) for a tight valve in the morning, but it holds a steady valve adjustment. -- -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: If privacy is outlawed, only outlaws will have privacy. -- Philip Zimmermann iEYEARECAAYFAk7gdAIACgkQlZadkQh/RmEfpwCfWEi0VBHFX+5bxTmljvbPxcLR Mg0AoKrRH66FVuZA2ePXSzlRGhCOwRes =kBHm -----END PGP SIGNATURE----- |

It could very well be that the fuel metering on the replacement carb is out of whack, I'm thinking idle and transition circuit. Also make sure the base setting of the butterfly is spot on(choke 100% off, slack throttle cable, the screw on top of the long lever facing the rear -> off its stop on the carb body, screw it in until it barely touches the stop, then 1/4 turn inwards). Make sure to check the two rubber boots/grommets(I forget the name) on the intake very carefully, have been burned there myself once. J. Ps. Unless the Mallory comes with a vacuum sensor i would stick to the svda dizzy. Pps. A tight valve would only get worse as the engine heats up. -- P.J.Berg --- Posted via news://freenews.netfront.net/ - Complaints to --- |
