O.K. so I get the idle circuit working almost. Far from what it was months ago but o.k.- just a bit of backfire and no spitting. So it's time to drive some distance and see how things work on the main circuit. For various reasons I have only driven the car up the street and back so it's mostly been idle circuit. So... warm up drive about three city blocks and it's almost fine( encouraged!) come back and do it again. This time, on return, I notice a bit of heat on the one side-i.e boiling fuel. Not much but some. So... off for the third run. I might also mention that I'm punching it here and appreciate the response. I'm really pleased at how fast the engine revs and how fast the car is.... BUT about half way out all hell breaks loose. I have smoke billowing from the hood. Stop and open the hood to see flames.( I got to test my extinguisher)Nothing destroyed so I try to restart. Every time I restart I see fuel spurting from the hole between the jets( I have the small screen off now). Needless to say not a good situation. I take the top off two carbs and the floats don't seem to be sticking. I'm just getting too much fuel pushed through on the main circuit.
Here is what I have and would appreciate any help. I noticed in the most recent posts that fuel/heat sink problems come with these carbs but I really have an unsafe situation at this point-
Engine- 306
Carbs- 48IDA
Main.... F11 Emul tube
155 main jet
200 air corrector jet
Idle......60 idle jet
1.0 holder
exhaust valve 50
choke 37
needle valve 200
Most of this/and changes are from conversation with Jim Ingelese but I thought I'd start here before asking him for help.
Any and all ideas will be greatly appreciated. If' I wasn't scared to death at this point I'd just be depressed with what happened today
. Thanks Jon
