My Feedback: (3)

Ok guys now i have one of these motors.. What can i do to it..???? lol and i am absolutley serious... i want my new hull to scream......Is there any way to remove the STOCK muffler? and what would be a good a good prop? it is

My pics are gettin' thin, but we'll try and start with some, first pic is the last TT o/b I did up (aircooled). The header on the left is the one you want to get. Old school pic, the way I did them years ago,, and the possibilities with the TT geared lower. Theres other stuff thats a "must" too.

JWMods

First pic is a couple well used parts to show the relief grind that made to clear the header cup. I use a table spool sander for that job and go until I reveal half the lower locator pin.

Second is a good shot of the way I do it now.

And the Third is a real bad boy, its a TT21BX-R EVO case long stroke buggy engine. Fair amount of work to do on this unit,, I use a Mac o/b head button trimmed on the lathe to fit the TT sleeve. I used the Mac o/b water jacket too but theres never any water used thru it. Its my "cool with fuel" method while runnin 65% fuel,, I call that model "Beetle Bomb" (BB). It is a serious motor for heat racing, it can match speed with the best 21 o/b's I have. The sleeve in this engine looks just like the pre 2000 Nova sleeve that everyone was using on o/b's. It is light years ahead of the sleeve that's in the original TT o/b with slightly better timing but they still
have to be brought up with sleeve shims to make things right.

I use and modify the XM's O.S.20J carb on almost every 21 o/b I run,, they're That Good.

what do these outboards run? price wise.

my brother in law has an old old dumas hotshot 3.5.... the K&B is TOAST

the bottom of the rod is ripped OUT completely.
also one of the lower unit halves is broken inhalf lol.

JWMods

Around $200 plus a touch,

andybenton

not bad at all, im assuming i can actually get parts, scince with this kb 3.5 its kinda a crap shoot lol. you might find them you might not, and if you do find them theres a good posibility that they are allready in another motor,   may as well get a hole new 3.5 ob lol.

I like the K&B's over OS or TT parts arnt hard to find most can be ordered new and my local hobby shop has a couple boxes under the counter of old K&B parts which was handy

JWMods

I never liked the K&B 3.5 outboard,, but I did like the 7.5 and the 11cc o/b units,, I could make them run pretty well.

Parts for the TT o/b? ,,, uhhh, I'm not really sure,, I would contact Ace Hobby Distributors,, they could tell you what the availability are of parts.
I had a cabinet full of new o/b's and parts at one time, but now down to 2 NIB o/b's and just a small box of NIP parts. Piston& sleeve,
maybe one set, one rod, some wrist pins and clips,, and various attachment parts. Have several parts for the Long Stroke BX-R Evo
buggy engine and a couple of each NIB pull start buggy (for o/b's) and the non-pullstart for I/B use.

i may see what i cant find for the k&b now. i started looking about a year ago, and never found anything worth mentioning. other than some ebay stuff.
