1966 Cub

ssechrist · #1 02-07-2013, 11:13 PM

Hello everyone, I finally found enough time to start working on my new toy!! I found the serial number & learned that its a 1966 model. I got a little further tuning it up, it was badly needed. I got it to start by priming it but its not getting fuel, I think that carb bowl may be full of trash or the float may be bad. If anyone has tips on this such as float setting, etc, I would appreciate any info. On a side note, I think the neatest thing I've found is that the bolt heads have the IH emblem on them, ya just don't see that kinda stuff these days.

if your not getting gas VIA the carb. take it off , pull the bowl off . in the center is the jet. take it out. you may need some heat on it to get it out. this is a catchall for every thing that comes from the tank. the jet is brass so be careful, thats why I say heat the area up first.

That jet does not need to be removed to clean the carb. It's too easy to destroy. Get a gallon of carb cleaner, disassemble the carb (except for the jet) and soak it.

I have rebuilt at least 40 carbs and not once have I had to remove that jet...

sorry bro but your wrong there. your just throwing the dice, and hoping the 6 tiny holes in the tube come clean.

Neighbor and I invested in an ultrasonic cleaner from harbor freight. The results were pretty impressive. Some stubborn issues remaining after a "bucket soak" with carb cleaner were resolved with the ultrasonic. Some of the residue that came from the carbs would simply not dissolve in carb cleaner. Loose metal oxide particles or rubber bits from dissolved rubber fuel lines did get vibrated loose. If they would have been removed by a shot of compressed air - who knows?

A bucket soak didn't help this puppy - if the carb cleaner solvent can't physically reach the blockage, it can't possibly have a chance to dissolve it. Different approaches may be required to resolve varying degrees of carb issues.

The carb cleaner dissolved the vaseline-like buildup but did not touch the salt-like grains in the bowl or main tube.

Thanks for the info, that'll be my project for tonight!!!

@Brent, I live in Moore Ok....

Hey neighbor, how about some pho-tos of this jewel?

We Oklahomans are going to have to meet up one of these days.

40+ carbs and 100% success, even with some really nasty ones nearly as bad as save_old_iron's picture, and I'm wrong?...oh, please. How many carbs have you soaked in carb cleaner that didn't work correctly afterwards because those holes were still plugged?

Regardless of whether or not the bucket soak works, it'd be better to try that first instead of just removing the jet first, which is fragile and easy to break. Not to mention it's also probably NLA or very expensive if it is still available new. Why take the risk if it's not needed?

This company makes main fuel jets new for stock Carter carburetors. Scroll down a quarter of the page roughly. $15 plus shipping.

Edit: Link did not work, the company's name was A-1 Millers Performance Enterprises. Looked like to me he sold pulling tractor items and stock garden tractor parts too, stuff that Kohler still has in stock and some NLA parts.............

Obviously not available by Kohler, but if one screws it up while getting it out they can still get one from an aftermarket source. Sounds like a fair price to me if its something you need to get going again...

Im thinking in the 50+ tractors I have owned (and trust me, all of them have had the carb apart at one time), I think I've taken two or three of the main jets out because soaking, compressed air and carb cleaner wouldn't get that jet clean. 95 percent of the time its not necessary, but I've had cases where PO have used some pretty nasty, dirty fuel OR where they attempted to start an engine that had tons of varnished chunks of S$$$ in the bottom of the bowl and they got sucked up in the main jet.

But I do agree, its a very rare occurence that one needs to pull that out. And I also agree that sometimes one needs to pull it out. Doug has the right idea of giving it a little heat/penetration oil so it dosent get screwed up
