![]() polish the copper entering the pump ( better reflection? lower emissivity?), add more insulation, go to 10% diesel. Some suggestions from some folks on the tour: change the line from copper to SS. With the higher percentage diesel in the morning with a cool engine, it seemed to have a periodic misfire that disappeared after about 5 minutes, medium to high throttle and then warm engine. ![]() Almost ALWAYS fired irregularly but cleared after 7-10 seconds to consistent cylinder firing. Almost AWLAYS needed to choke it AND use about 1/4 foot throttle to start. Starting was always hard so I started to pour a little water on the fuel line to carburetor ( I have it insulated and assumed that the water-soaking would result in transpirational cooling - alas, still hard start). Friends told me they did not see smoke at any time from 5-7 to maybe 3ish%.īy day four, I was really tapering off the diesel addition shooting for 3-4ish% I just was getting frustrated with the harder starting.Īdditional measures after any run then tour stop was to open hood to aid cooling AND pour a little water on the fuel pump. ![]() Observed another car using 10% diesel - and significant exhaust smoke. During the heat of the day, the car was hard to start - it would fire on a cylinder or two then require chiocking to get it to start and it was almost always irregular - not all cylinders firing then cleared to all cylinders firing in 10-12 seconds. So decided next iteration was back to 5%. Increased diesel to ~7%.Īfter ~7%, starting was a little 'harder'. Continued harder starting or rather slower starting - typically, it fires on the first few revolutions of starter. I have NOT yet examined spark plugs.ĭay 2 - higher temps by a degree and one instance of vapor lock - with ~5% diesel AND cleared by use of electric pump. ![]() That afternoon I added about a 5% addition of diesel - ( temps about 92), I did have some difficulty starting the hot engine ' hot start' then carburetor vaporization?Īfter diesel addition, and the next morning especially, the car was a little harder to start. I did have some increased temperature but not severe over-heating. On day one after a long climb, the Chevy started to vapor lock and the use of the electric fuel fixed the solution but as soon as I cleared the vapor locking, I then turned off the pump. The tour did not have excessive long runs ( >30 miles at a clip) and only several fairly long hills ( 5% grade for about 1 mile). Conditions were tougher - daytime temperatures were 90 to about 93 with humidity varying. Well, an update of conditions and observations. ![]()
