A decent 1975 Palma Green came to me last year, from Cali with very little rust and original paint. She was running ok with a single carb. I changed it out to a set of twin 40 IDF Webers and she has not run decent since. The cheapskate in me has considered simply sending Tangerine $400. and getting it right, but ...
I can get a smooth idle at 5 -6 on a snail, but increasing the throttle opening a small amount I cannot get equal air readings from 1-2 to 3-4. Compression ranges from 110 to 125, leakdown ranges from 5%-18%, valve clearances at .006. The characteristic popping and poor running are the result of this unbalance condition. thanks in advance |

Thanks for the replies. Spark timing is good, idle speed screws are about 3/4 turn in, mixture screws are about 1 - 1 1/2 turn out. It seems as though the carbs are not being activated at the same rate. I have a CSP setup, but mistakenly ordered assembly that works with a 911 style fan. I may send it back or put it up for sale here.
Tangerine will be my first call today. I have a pile of FI (both D and L jet) stuff laying around, it may be smart to inventory the stuff and give it a try. |
