Some guidance on what amp fuses and where to put them would be fantastic!

Ditto! Just a question for you JB owners. If I ever get one I like Leon's installation and or others similar. Isn't the JB a bit too large and heavy for cart applications? Wouldn't a semi-permanent install be the most desired way to go?

Tradeoffs. Nice thing I see about being in a garage is it may not get any condensation on it. If outside Cold soak during night, then condensation on it from warm moist air in AM , like dew on the lawn. We had a model A ford in a unheated cement floor 3 stall detached garage for ~60 years, no condensation/rust at all.

Here metal gets wet with condensation, especially for 2-3 weeks straight in spring when heavy metal is dripping wet with condensation.

Depends on what local code has to say about what constitutes permanent. It might be why you see so many of these retired Onans made self contained and getting mounted on to trailers.

I had a 15.0JC on a cart. That was able to roll it on flat ground that was either concrete or asphalt. On grass or dirt I would need to tug it along with my SUV. The JC weighs about 350 lbs more than a JC. I'll let you know how easy it is to move my JB on a cart when I finish it in the year 2025.

Need big tires to roll it. I got my JB temporarily on a boat trailer with 4.80-8 tires ( 15.5 inch OD) hard to roll on packed ground against very slight incline..

So- the flower show was great actually lots of hardscapes, not really many flowers, 1/2 ways to you JohnnyC, just over the bridge, 1st x on 287, Edison expo center. Lots of free food and wine,

JohnnyC- build sheet is on page 1, C1, combo carb F56-Air shutters H49-HATKO H1-LOPKO H13-oil base heater/120V only 1phase, will snap pick of plate, hope to play tomorrow. Did a little today, coil does not look like the ones i have seen (6V) it tested good, think it was around 11K, wires are off the wall super high resistance and 1 is tripple from the other. ?? Need to clean all the ignition components and proceed from there. Will snap pic of coil to see if it looks familiar, only has the 2 plug wires w/ no caps on them. no side terminal and its round and longer, not short and stubby like the 6V, there is a condenser hiding behind it, looks like toast.

Quickly checked under point cover, cond. looks fine, points pitted, and need to figure how centrifugal switch works, does not look like it closes at all, might need to re-gap, not familiar w/it.
