Much obliged to the admins for resurrecting this site.

I updated this thread just now. Thoughts?

<whew the forum is back, awesome!>

I noticed in the Max II manual there are references to parking/auxiliary brake, and how to set it. My Max II does not have any mechanism there, so this was...

Necro-bump. I'm in the Puget sound area, 1994 Max II, had it for several months, just repowered and working on heat abatements, but otherwise ready to rock. Seems like the ATV trails listed on...

Took the re-powered Max II out for a spin with my better half over the weekend for about 90 minutes, up/down some steep terrain and ugly 4x4 trails (Timber Tamer and EZ Connector, Walker Valley ORV...

I re-powered my Max II with a replacement Briggs 23 HP, and the old one is going to the metal recyclers once I'm done parting it out. It's a 386447-1138-G1, made in 2012. Just about everything...

In another thread there was a good discussion going on about whether to use a Briggs 23HP engine in a Max II, due to overheating reports from some forum members. I had bought a used '94 Max II with...

Permatex Aviation Form-A-Gasket No. 3 Sealant Liquid #80019 did work well for me on my Max II plastic fuel tank. After cleaning a couple pine needles and grains of sand from the tank interior, I...

Lots of board threads on how to clean plastic and metal fuel tanks, but nothing found on what sealant I should use when reinstalling the 90 degree elbow fitting on the tank where the fuel line...

Posting to old thread. Dealer for re-power 23hp Briggs I just bought said the carb needles on these engine series can only take 1 to 2 PSI. Any more than that could cause the needle to unseat in...

New B&S 23 engine came in (386447-0090-G1, mfg August 2021) today for my Max II. Of course, it was slightly damaged in shipping as seems common among the posts on this forum. Dealer says Vanguard...

Thanks Noel Woods and Johnboy for your input. I'm going to gamble on the B&S Vanguard 23, specifically 386447-0090-G1 which is the latest revised model with a one-inch crankshaft 2-29/32" long,...

Thanks Noel Woods for the detailed reply. What manufacture year or year range was your past B&S 23 experiences? Also, a correction to my last post, the fans I planned to use are 80W 650CFM but...

Tagging along on this topic, as I also have to replace my engine.

I keep seeing back-and-forth comments about Vanguard 23 engines. Works fine for some, overheats a little but fans can beat it for...

FWIW, in WA I went through the titling process but did not have any old documents as my Max II is at least third-hand by now. I provided the manufacture year, and WA DMV was able to find Recreatives...

ARGOJIM, sadly you were right. Camshaft exploded spectacularly and destroyed everything around it.

I'm gonna need a little time before my "fun money" account is ready for an engine replacement. ...

Catastrophe strikes.

New fuel pump and better spark plugs solved the sputter-from-idle problem. It ran great under no-load for probably 20-30 minutes and I could rev it up under various...

I read a lot of threads that say Vanguard 23hp engines tend to overheat when trapped in the belly of an AATV, even if say it's a Max II and all the engine vents have been carved out in the back for...
