Default Sport Jett 120

Bob, I see they are discontinued. When was the cutoff date? And how much did they sell for before they were discontinued?

Thanks!

The big-block 120 was last sold in 2002 I think.

The BSE-120L came out in 2003 - Dub shut that down in 2006 since he only sold a handful of them.

Cost about $40 more than a BSE-100L

The cast case big-block was a heck of an engine

$.05 part stops me in my tracks.

I swear I put the wrist pin retainer in a safe place where I would find it again. NOT!!

So I had to place an order for a single wrist pin retainer. I bet Dub will get a kick out of that!

I ordered a remote needle valve at the same time for this engine.

LOL...

I saw that this morning....

I sat there imagining that "TINGG...... ping...... " sound as a retainer went flying across the room while trying to be reinstalled.

The remote is a good idea. Actually makes cowling the engine easier .... you do not have to deal with cutting/locating the carb mounted needle valve location quite as much.

Bob, I got another question. I received the retainers and remote needle valve assembly today.

How am I supposed to close off where the stock needle went? I thought the Universal Remote Needle Valve kit would have included a closed nut or something but all I got was the remote needle valve assembly and nothing to close off the port in the stock carb.

Dub wrote me back and has a special screw to close it off. Problem solved, thanks.

For a while ( a few years ago) the URNVA sent to known Jett owners included the screw. Since most of the needles are sold for "other" engines these days and the jett carb changed 5-6 years ago, he typically does not include that screw.

Problem solved is good. I think its a 3-56 x 1/2" screw ..... yes, weird size.

If it was 3-48 you could steal the 3-48 x 7/16" prop screw from a Pee Wee or Tee Dee .020.

Bob, could you please remind me what size prop to run the Sport 120 with?

Is it any different than the requirement for the BSE version?

BSE 1.20L R/C with muffler** AAC
9,200
16x8

Same props.....

Turns the 16x8 with authority.

I've always flown mine a 15x8 or 16x6 just to let it spool up a bit quicker.
