Holley question
Fired up my fresh engines last night, had a few backfires before first runs, one engine running good, other acts very rich- from idle all the way up to 3000 would a blown power valve cause this ? If I remember correctly I should be able to look in carb and see extra fuel pouring in? first time around Holley's. Randy

If you have fresh engines in the boat its probably time to put a couple of kits in the carbs anyways , even the cheap kit for my holley had a pair of 6.5 power valves , even tho my carb only uses 1 power valve

while idling you should not see any fuel dripping in, if you do ck float level(site plug side of bowl) or trash in needle & seat, if thats ok, pull the fuel bowls & metering blocks, look at the diapham of the power valve, if it's wet it's blown, may have 1 or 2 if it did blow and if its a older carb by a power valve protection kit and install with the new power valves. set float level so fuel right at bottom site plug, good luck, Rob
