Since my carb is about 8 yrs old and the engine's been idle for ~2-1/2 years (except for being run on the trlr every 4-6 months) and Holley's website plain sucks anymore for marine carb part info, I thought I'd pick up a renew kit for the 4160 on my PCM 351, just in case, before any reference to carbs evaporated off into oblivion.
Carb list number(s) 75009; 1757 (stamped on port side front of air horn).
First looked at Disc. Inb. Marine for a listing on one of their kits (just for reference), no match to my list number(s).
Called Holley's tech line and they told me that those number(s) weren't for any carb in their database and asked me if I was sure that it was a Holley (duh! why does it have Holley cast into the fuel bowls :x ).
Tried calling PCM, that's like beating your head against the wall, they told me to call D.I.M. Have now come full circle on that loop.:?
As a last effort, went to my local speed shop (Holley dlr) with numbers in fist. The first guy I talked to couldn't find a reference for the list number(s) - asked me if I was sure it was a Holley, been there, done that :!:
The store manager overheard the conversation and asked me for the numbers again. He went to his own notes in their Holley parts catalog and found the 75009 number penned in in a blank area. He remembered that a local mechanic was in a few months ago looking for exactly that list number for two carbs he was reworking.
As it turns out, the speed shop guy somehow found out that the Holley renew kit, number: 703-29, was the one for that carb. Cost: $30, discounted from $45.
I've rebuilt a couple Holley carbs on both BB and SB Ford automotive engines and have never had this problem finding renew kits for them. :shock:
I now have it in my grubby paws and if I have to rebuild the carb, we'll find out if it's the correct kit.
Pardon the rant, but it's been a bad automotive week in the family, two elusive CELs and one blown head gasket. Hopefully, the $#!t is done hitting the fan. :?
