Re: [T3] FI to Carbs by PO not running right.

[Steven Ayres <comwest@att.net>]

<x-flowed>RichardG=> He says it sounds good but is only running on two
=> cylinders. the 3, 4 bank. They have pulled the plug wires and
=> only two make a difference. He says that he thinks it is running
=> hot on the 1,2 bank.

Obviously 1/2 can't be running hot if they're not firing, so something's 
confused here. Let's say you mean that he thinks he's getting little 
power and extra heat from 1/2. Correct me if I'm wrong there.

The common Bentley will be no help in dealing with the carbs. There is 
an earlier out-of-print Bentley edition that is helpful, as well as the 
easy-to-find Haynes. The Muir is fun but ultimately of little use in 
this sort of detail.

First, on your reference to the 'progressive' carb on hand and 
aftermarket FI: don't complicate your life. The PDSITs are a fine choice 
for this car, will do great for him, and will be a whole lot less hassle.

=> He has seen fuel boil on that side.

Where? How?

Make sure he installed the phenolic spacers under the carbs -- they help 
insulate the carb from head heat.

=>  is using it without the cover on the cylinders to get it running.
=> I said this is not good.

You're right, and further, having the tin off doesn't help anything 
diagnostically.

=> I told him that the 1,2 bank is running very lean, ...

You may be right, but in what you've written I don't see any way to 
conclude that yet.

See if you can get more specific information on the symptoms. For 
example, he says 'hot' -- from what does he conclude this? To give any 
useful advice we'll need to know all we can about what exactly is happening.

You mentioned that he rebuilt one of the carbs. Which one? Does he have 
experience with this? Did he find any problems? What did he replace, and 
where did he get the parts?
