Type 3 hot

[Rex lucy]

my t3 engine run too hot on the 3 and 4 cylinders. so hot the gas in in that carb boils. valves adjusted , timing set at 5 degrees advance, running a 010 distributor,all air shields are intact. dual carbs, electric pump, 80 miles on rebuild, no evidence of vacuum leak. could it be float level valve in the carb for 3 &4 flooding. cylinders 1 & 2 run at about 170 degrees while 3 & 4 run over 210.
got me scratching my head.

80 miles is not enough to be broken in yet. It will get real hot while you are breaking it in

distributor should be 28-30 degrees at full advance, not 5 static. Try that and let us know

Sounds like it's running to lean on that bank.

i've got a old time timing light so i reset timing to 0 degrees and reset that carb to a richer mixture. resetting timing reduces performance somewhat but will do a longer drive to check.

You can't just set it to zero. you need to do 28-30 degrees at full advance. 3K RPM's. Thats how you time a mechanical only distributor

what pully do you have? what timing marks? Generally 2 and a half "humps" over from zero is what you aim for at 3K rpm

Yup, it's just like timing an 009 distributor. Set the timing at 28 to 30 degrees at 3,000 rpms, and let the idle timing fall where it will.

Sounds ok to me only can someone tell me how far 28 degrees would be from tdc. its a stock t3 with stock timing hole. i guess i will invest in an updated timing light that i understand can be set to get that setting without measuring. etc. thanks for response will update outcome.

well , finally got an advance timing light and timed it to 28 advance but still did not improve. after much head scratching and reviewing the manual and researching Samba I checked those short connecting rod on each side of the carbs. one was 1/4 in longer than the other making carbs out of adjustment except a idle. all is cool now. even got the capri top installed.
