shop recommendations- Nor Cal

[hntz4x4]

I'm wondering if anyone can recommend a shop that can work on my 87 Marathon? Im near Sacramento, so maybe somewhere within 100 miles? Every place I have contacted only does electric carts or nothing that old.

I've thrown a ton of parts at it and it still doesn't run right. Will only get up to 12-13 mph and its ungoverned, and struggles to make it up a hill. I don't have a lot of time to dedicate to this. Considered selling it, but wife really digs it. We bought to use at campgrounds and such.

New belts
Top end rebuilt
New carb
New fuel pump
Compression was around 110 last time I checked
22" tires

Thanks Ryan
