big max????

[jpswift1]

thanks guys for all the info so big maxs were only two stroke how does a two stroke power wise run to my 4 stroke 18 horse vanguard

All Big Maxes were 2 strokes......if you're going for speed, a 2 stroke is the way to go! It will outrun just about any comparable 4 stroke out there.

This is what mine had in it. Don converted it to 4 stroke for me. I still have it. keeps the snow off my trailer.

Marty,

Get that thing of the trailer and drive it. Btw hopefully this weekend I will finally mount those tires I got of you...I havn't had much stick time myself lately. That's just the way it goes sometimes.

I have a Big Max that has a JLO 440 in it. It had had a roll bar at one time...now missing (am looking for one). Since you guys have Big Maxes, can one of you email me a picture of the engine mounting plate. Mine looks really kludged together. Additionally, if you no longer are running the 440 JLO, I would like to find an engine mounting plate that has not been modified.
I am still struggling with my engine which I just rebuilt.
I would like to find a black pleated with gold piping bottom seat cushion. Mine has been custom modified . .I still have the rear sea cushion...jsut not the bottom.

Does any one know, or have any info on the Kohler engine that it used to come out with. It's red with the roll bar. We don't know what size the engine is except it's 42cc, 2 stroke 2 cylinder, t20 tyranny and there's about all we know. Thank you in advance for any info.

Maybe a typo? 42cc would be a pretty small engine lol.
