Re: steering gearbox oil
Does corn head grease get warm enough to actually flow through a steering box that isn’t generating very much heat through friction? My 7-tooth box’s lower bearing fell apart and the pieces...

Re: No Spark - NEED HELP! UPDATE
Did you check TDC with the pin on the timing gear and confirm by visually inspecting the piston through the spark plug hole? I’d start there to confirm the timing gear isn’t compromised, and then...

Re: Zenith Idle Mix Screw Doesn’t Kill Engine
Interesting! I was going by what the owner’s manual says about running it anywhere between 1/8 open or closing it entirely. My roadster always runs really well when using that setting, unless of...

Re: Zenith Idle Mix Screw Doesn’t Kill Engine

Re: Zenith Idle Mix Screw Doesn’t Kill Engine
The idle speed is set very low. I’ve swapped this carb onto my roadster and it has the same issues. When set to the same RPM, the roadster’s idle mix functions normally, but my friend’s truck’s carb...

Re: Zenith Idle Mix Screw Doesn’t Kill Engine
Thank you for the input so far. To add to this: the screw doesn’t really change anything until it is either tightened in the whole way, which makes the weird sucking noise, or it is backed out so far...

Zenith Idle Mix Screw Doesn’t Kill Engine
Hello all,
I’ve been trying to tune a friend’s Zenith and eliminate the stalling while stopping feature. I found that the idle mix screw seems to have no effect on the idling of the engine. I can...

Re: Speedo cable noise...
Good to hear! When I replaced my cable, I saved the ends off of the old cable so I could spin my speedometer easily with a drill.

Re: Chuck Koontz
I recently bought a part from Chuck. The time between comms and receiving the part was a little slow, but I couldn’t have been happier with what he sent me and what I paid. I’d definitely buy from...

Re: 7 tooth steering gear box rebuild
I’m pretty sure that corn head grease is why I just had to rebuild my steering box. The lower bearing broke into a bunch of small pieces that absolutely destroyed the end of the shaft and the lower...

Instrument Cluster Light ‘28-30

I need the little cover that goes on the dash light for my ‘29 A. I’d prefer to buy the cover by itself, but if you have the full light assembly and won’t separate the parts, I’d be...

Yeah, by “tightening up” I meant that I would be dumping hundreds of dollars into parts and time with the machine shop, just to slap a band-aid on a poorly designed piece of technology. Also, there...
