Warning! The Inspector For The Parker 300 Has Stated That There Will Be No Tolerance On Carburetor Measurements. The Rules States That The Venturi's Must Measure No Larger Than 1 5/16'. rod

Rod,

May want to have them check before the race during inspection for those unsure.

Racer 55 is absolutely right make certain your carb is legal BEFORE the race, you may not have time to replace the carbs if they are too large at the venturi. Inspector Roger Carr has stated that there will be NO TOLERANCE given since it is not so stated in the rules. I just received a set of WH-46'S. I was told they were bone stock and the venturi's had not been touched--they measure too large. The venturi measures 1 3/8" and my GO-NO GO gage slides right in. It is a very simple procedure to make a measuring device out of a peice of aluminum that measures 1 5/16" for the first half inch or so then steps out to 1 3/8". The measuring device will slip right into a legal carb and will stop when the step out is reached. DON'T WAIT TIL RACE DAY THEN CRY I DIDN'T KNOW--Call if you have questions. Rod

So which carbs measure 1 5/16? Are you sure that whoever set the rules could have miss measured? I cant' believe mercury would make one carb with 1 5/16 and another at 1 3/8 does not make sense!

All the carbs in 2L class were checked at inspection last year and passed. Like capnzee said, better check them.

good luck to everybody racing this weekend!!!

Both of our engines measured 1 5/16...both came from Chris Fairchild...Personally, I've got not problem opening Classic Mod VP to 1 3/8 as there are many carbs out there that size.....But with any size, a PLUS needs to be established....No need for a minus in a carb size....

Say 1 3/8 plus .030 for Classic MOD VP, no machine work allowed...as I see no reason to start allowing someone to machine their carbs to 1 3/8 plus .029....I'm saying make all carbs that Merc made legal...make it EASY for people, not difficult!!!!

[capnzee]

Great idea for the future Ron, but for now I am afraid we are stuck with the rule--carb venturi MUST measure 1 5/16" or less to be legal for the Parker 30 2008. Incidentally, there are a million carburetors out there that are of legal measurement, as well as there are a million carburetors out there that are illegal. Rod

So....how are you checking to see if the 2.0 liter is not a bridgeport/behind the liner type that MUST run 1" carbs?


Thanks - Franky

That is an excellent question, I would direct that question to Roger Carr, the inspector. Would he pull the head, use a borescope, pull the front half??I suppose he could do all of those things or any one of them. Roger, if you are up on this thread, please feel free to jump in. Rod
