I never run premium since its harder to burn unless compression is really high, hhis could have been some of you problem, Im not sure what you jetting was either but ghat may have been some of why you noticed it getting hotter and not wanting to idle right.

Main thing is you got it back uto running the way you like it and thats all that matters, personally I have never had any issues running Opti2 all my engines run great on it at 100:1 and actually other mix ratios as well since the small packets actually mix @ 72:1 which I ran for a long time without issue.

Glad you got it how you like it to run so enjoy and stay safe.

Yeah, I just freaked out and dropped the big one on all changes.
I have the bottle of opti 2 waiting in the wings, but I shall never feed it premium again.
I like the spare magnet, it is an excellent magnet removal tool. It sticks to the one being removed and both come off easy as pie.
The carb is a RT type, I went from a dellorto 66 to a 65 back to the 66.
My gas station is not the flashiest one in town, if you know what I mean.

On my 48cc Bridgestone the factory gap is 3 fag pak cardboards.
My clutch pads are worn out bad so im gonna get new one from dealears, they sell same motors as boat trolling motors now, but clutches are the same.
Anyway, i find my clutch on websites for $13.oo however, the Bridgestone factory clutch is $ 70.oo . I'll get the Bridgestone clutch and then get HP springs fron other websites.
Yep for Briggs use a recipe card bring the coil down to the magnets with it in tighten it up and work the card out good to go........Curt

Finally swapped out carbs --- NT Speed for a CNS. Wished I had done this sooner!! Quite bit of difference. Hopefully the constant 'chasing the optimal tune' is over.

Disassembled my homemade exhaust. Gonna change it so I can add a rear caliper brake. Hopefully, I can also install the new 36 tooth sprocket with hub adapter this weekend.

Well, tested the new exhaust --- calling it version 3.3. Redneck engineering at it's not so finest! Used the cut off manifold flange from an old muffler, added a conduit connector, threaded on a used water heater copper flex line, and re-used the riding mower muffler with the stainless steel scrubby stuffed in it. So far it works just dandy. Maybe I'll try an extended ride this weekend to see if it's really OK......LOL!

Didn't do much with mine today but I got my 18mm Mikuni carb and manifold waiting to be installed, Got a few KX65 pipes to rearrange for bicycle use, and then tonight I stopped by Harbor Freight... mainly to buy a few tools for the shop and walked out with a 12 ton tubing bender, a band saw, and about another $150 or so worth of supplies for the shop.. Now I just need to make me a notcher and a frame jig...

First I gutted rear hub on the Huffy Karaoke Bike, has a Falcon-SHA Hub if I remember right, haven't touched the hub or greased it in at least 1000 miles, noticed just a little bit of slack in bearings so I figured it was time to service it and re-pack bearings with some good grease.

This bike will be getting new rubber also, noticed some weather cracking on sidewalls.

Below are pix of the coaster hub parts after a good cleaning before they got a good coating of water proof Green Grease and put back together, you'll notice how good everything looks, bearing race area in hub looks just as good as the internal parts, I know some cuss the Huffy wheels and that may be because they don't use these Falcon hubs in all of them, I don't know, but I do know that mine here has had about as much abuse as you could put one through since 2010 when I motorized this bike and everything still looks about as good as new, very little wear even showing on the brake shoes, thankful i got a good one, strong steel rim and 12ga spokes for the wheel.
