Since I got the 1953 Chevy I have notice that when I start it I get a lot of black thrown crud out the tail pipe when It first start it up. Also when parked and idling I get black deposits on the ground. My friend followed me home and say he could see puff of black smoke at the gear changes. The truck start very easily and I don’t think it would even need choke when cold is 2 C here. I check the plugs and the are covered in black soot, not oil black soot.
I think it’s probably over fuelling for some reason. Could be stuck float, but don’t really know the causes of such problems. I have ordered a rebuild kit from ebay for the 216 single barrel Rochester carburettor and plan to try rebuilding it. I have never opened up a carburettor and a little bit daunted at the idea.
I noticed I can get a replacement carb from classic parts but it carries this warning:
Rebuilt Rochester 1 barrel type only. This is a rebuilt carburettor and we will need a good core to have it rebuilt. Mounting bolt to bolt center measurement is 2 3/4" . Price does not include a $100.00 Core charge. **All carburettor cores that are returned have to be just like the one in the picture and no carbs with a choke.** **DO NOT USE ETHENOL FUEL AS THESE OLDER CARBS OVER TIME WILL NOT WORK OR PERFORM AS ORIGINAL**
My understanding is that all fuel in the UK now contains ethanol so wasn’t sure how to proceed with this.
Heard a few people mentioning using a Carter carburettor with electric choke. Most appear to be fitting these to the 235 engine rather than the 216 that i own.
So as usual just look for some general advice of how to proceed with investigating the problem, Carb rebuild or replacement options.
I have to say I am a very lazy mechanic so if there is an easy fix that just involves throwing some money at the problem that’s probably my preferred solution.
Please could you give me some thought ideas etc on how to proceed.
Thanks in advance for any comments and advice
Chris
