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 |

After trying all the x bar linkage..and I know how to tune carbs, I would suggest you call Foley.
BUT, tune as stated above, jet changes may help. Buy the jet kit, read up and get it perfect. Only then will you see the slight difference the linkage makes. |

I spoke with Chris this morning and too bad he has none in stock, but informed me in a couple weeks he will be able to ship me a setup. I feel my jets are close, at least the idle circuit |
