Yes Mike, we (Bob and I) are going to North Carolina to spin my valvetrain. Why? Because nobody has a clue what kind of valve spring we need. Not even the guy that owns the spintron. Hes clueless. So you say why put all that cam in a pleasure boat? Simple because I can because it's mine and that's what I want. Did I need do spend $4000 on an oil pan no. Why did you? simple. Because that's what I wanted. I have a lot of reasons for building my motor the way I want to and frankly it's none of your buisness why I do it.

As far as Quick fuel carbs go. Nah not for me they use Chineese parts in their carbs. You can take that check to the bank and crash it to. Why do you think they cost less than other carbs. But it's whatever I really don't care what you use. Just not for me. But the problem I have about it is you push everyone to think that your preference is the only way. Well I'm really sorry bud there is a lot of bad azz carbs out there. Way more bad azz than Quick Fuel. Do they cost more? Yes, but you get what you pay for. But to each his own.
And one more thing. So you can get over it on the wideband thing I have never told anyone not to use a wideband to tune and engine. I have two on my boat (why would I tell someone not to?) all I ever said is it's the responsible thing to pull a few plugs and check them. If you don't want to be responsible so be it. Whatever.

I don't think Mike, or myself, ever said quickfuel was the BEST carb out there. I think when him, or I, suggest that carb, is because they are solid carbs, with nice features, and very tuneable, at a reasonable cost.

Gimme a break with the chinese stuff already anyhow. Everybody's always on the "chinese" bandwagon. For one, i have some chinese friends who have some very bad azz cars, that also tune with widebands by the way. Secondly, if you think your 27 donzi fully rigged from bow to stern, is 100% every part made in america, you are sadly mistaken. We all use something every day that was made overseas somewhere. Maybe a microwave, coffee pot, cell phone, car part, tires, brake pads etc.

Probably half of the guys on oso building their own engines, are running some sort of imported forged steel component or fastener in their engines. If quickfuel does in fact use a "imported" metering block, or "imported" fuel bowl, I am fine with that. Its not like we are talking about some ebay imported 200 dollar crankshaft vs a winberg crankshaft here.

Maybe for my next set of carbs, I should do a full backround check on the CEO of the company. Make sure he shares my political views, religion, and make dam sure the accelerator pump rubber diaphram, is certified made in USA rubber.

sorry but no chineese parts in any quickfuel carb, they make in house their own billet base plates and metering blocks,they use proform body,s[made in usa]as far as you spintron testing for a pleasure boat engine and a 4 k oil pan,its your money .as far as it not being any of my buisness than why do you feel the need to post it.

I had the same issue as you, the "lean sneeze" just off idle followed by a backfire half the time. 1/4 turn out of the idle mixture screws solved that issue 100%.

Wait a minute .. who has a $4000 oil pan??!

Well that makes me feel 100x better... lol. Hope I get the same result!!!
Actually gonna try to tune it with vacuum gauge and find highest stable vacuum reading

on a single carb engine 1/8th of a turn can change idle afr reading as much as half a point.

i can,t imagine how any oil pan could cost 4000 bucks but maybe it is made from gold .just more of bb trash talk.

Don't be too sure about that. They were $5500 7 years ago. It's nothing new.

The Black Baja reverse inflation Oil pans. Fancy!

quickfuel carbs are the SH*T! ask me how i know.......i have two of them.

When Billet Blocks first came around they were upwards of 15k time goes on manufacturing processes / tooling gets better now you can jump into a billet block for 10k. It's the same deal with the oil pan. It's billet. I'd be willing to bet the chunk of aluminum it takes to make the pan is probably $1200 to $1500.

must be made in china to get such a good deal!WTF
