generac 6500 carb removal trick?

[sdowney717]

ok, bought it for 300$ and it needs carb cleaned. Has the Nikki carb on it.
I got the carb off but bent the control rod to get carb off engine. This long rod runs threw a drilled 3/8 hole in the engine cowl and also has a long tension spring to keep it tight.

the way they put it together, i cant believe you might have to undue the engine cowl cover.

also thinking of adding a small fuel filter
Any ideas on the proper way to remove the carb?

this is it here

ok, you have to take off the engine cowl to do it 'proper', otherwise the throttle rod is going to be bending and wont be straight.

With the cowl loose, in your hands, push the throttle rod threw both cowl holes
attach rod and tension spring end to governor lever on motor
set cowl sort of into position but loose not pressed into place yet
put carb on to mounting studs
put tension spring into carb throttle plate
press throttle rod into plate threw the plastic bushing
position cowl and carb into place and insert and tighten up cowl bolts
cowl and carb sort of go on at the same time, pain, should have been a better design, IMO
attach fuel line and should use a small plastic filter just in case!
hook up air filter housing attach kill switch wires
etc...

My carb now works perfect. The idle circuit was totally clogged, thing would not idle down and only ran while choked very roughly.

I cleaned the carb using
white vinegar soak
rubber ear bulb to blast vinegar threw passages
toothbrush
clean water to rinse
air to blast it clear

quite a bit of particles came out of the carb, the vinegar soak took at most an hour.
vinegar cleans very well.

I got bright and installed an inline fuel filter on a Dayton generator made by Genrac, a V twin, 10,000 watts. It would not run. I messed with it for a long time, and finally removed the filter and it ran fine. Not sure why, but the filter is too much restriction for the gravity feed to work properly.

this filter is a small white filter made for lawn mower and small engines. I think I got it from a small engine repair shop.
On a paper filter. You have a point on the gravity flow threw a metal automotive paper filter. You can do a test easy enough to see if fuel will flow with gravity.

Just about every small generator set I have seen comes with an inline filter... that said, I have learned from outboard engine techs that the alcohol that comes in gasoline (at least around here in the Eastern seaboard area) causes endless problems for engines that don't have sealed fuel storage tanks... like mowers, chain saws, outboards, generators, you name it! The lesson is, do not store fuel for more than a week in your device if you won't be using it. A chain saw repair shop guy told me that about 9 out of 10 saw problems come from gas issues. Additives won't help- the alcohol absorbs moisture from the air, and gunk results, or worse.

gas is pretty much garbage today.
PRI-G is the only stuff I have found which works and can restore old fuel.
Think of all the boats sitting around with the fuel slowly turning to goo in the tanks as the volatile components evaporate.

I was thinking next time the carb comes off of cutting an oval slot with the dremel to allow room for the throttle rod to move up and out of the carb throttle plate. Whoever made this engine did not consider what a pain to work on that arrangement is.

More about bad gas! A friend with a 100hp Honda outboard engine had gas-caused trouble with his carbs... after fixing the engine, he investigated some. Seems that Honda engines like his (non fuel injected) have built-in drains on the float bowls, and if you don't drain them between uses (hah! how many boat owners will be doing that?) Honda doesn't consider the resulting problems to be covered by warrantee. Or so he has been told. Thank the corn lobby for pushing the ethanol debacle- and there's talk of increasing the alcohol content?

not only that but High fructose corn syrup now proven to be a cancer fertilizer, so if you get a cancer cell which we all do and our immune system represses, then the cancer cells slurp up the HFCS. Plus HFCS makes you fat and contributes to diabetes.

seriously they need to stop pushing these corn artificially modified products. Let corn be food like it was meant to be.

"These findings show that cancer cells can readily metabolize fructose to increase proliferation," Dr. Anthony Heaney of UCLA's Jonsson Cancer Center and colleagues wrote.

"They have major significance for cancer patients given dietary refined fructose consumption, and indicate that efforts to reduce refined fructose intake or inhibit fructose-mediated actions may disrupt cancer growth."

Americans take in large amounts of fructose, mainly in high fructose corn syrup, a mix of fructose and glucose that is used in soft drinks, bread and a range of other foods.
