They do hold a certain amount of gas, though.

Guess I'll start looking....they come from Singapore?
OMG C.C.C., that's great ! The first one I found was from "Carburetor Capital of USA, Untited States", with very pretty women standing by to take my order ! I almost hit "Buy Now" ! Heh. Gotta love Fleabay.
Thanks !

Yeah, that first set looked like the ticket. while I'm waiting for the floats to get here I thought I should check the oil spinner. The oil on the dipstick looks like new, but if it's straight weight non detergent , might all be on the bottom, right ? So I'm going round the horn tapping on the screwdriver shocking the screws. No dice. Get out the hand impact driver. No dice. I quit. Thought I'd give them 24hrs. To think about it. Think I'm going to try the 1/4" electric impact driver next.
Good advice. Do you think they are more likely to come out, or twist off using the correct T handle ?
T-hande JIS ordered....Now that screw assortment brings up a question: How many of the screws on the '65 early are the oddball threads like the petcock screws ? Been doing a fair amount of reading, but haven't come across that yet.

So I used the 'lectric impact. Got the top two out no problemo. The bottom ovlal head proved problematic. Broke the No. 3 standard Phillips bit off and the "bitts" stuck in the screw. Bummer.
The two top cover screws are standard metric threads. The bottom countersunk screw is still refusing gentle persuasion.
Carb floats came today. They look good. Can't believe they ship those in just a bubble wrap envelope. They survived, tho.

I bought the T-handle driver. Nice, tho from Jina. I went to work on that stubborn lower screw again today. I was armed with five items from the pawn shop. Cost me all of three dollars. Two nail sets, a very slim punch, a small chisel, and a screw driver. After another hour of tickling that screw with micro- chisels, (made with the grinder),it let loose and came out. This was my first time extracting a screw this way, and I'm here to tell you , it takes a lot of patience. But once that baby budges, it's a great feeling. So now I need to get the oil spinner apart, get the new guts in the carb. Keep my fingers crossed about the petcock rebuild, and then...maybe take a spin.

I know how you all like pics, so here's the offending screw:

So I got that oil spinner apart this morning and there was a good 1/8" layer of crud on it. Probably around 8200 mi. worth. I had watched a vid on Ewetube about this. The " mechanic" was using a steel screwdriver to scrape the crud out. I was cringing watching him put scratches into the aluminum. I used a Popsicle stick and carb cleaner. But that's just me. There was also some really tough stuff in the "rim" areas where the two halves meet and the groove where the snapring goes. This stuff bordered on corrosion. I did use a tiny screwdriver to scape that down to metal. The o-ring was still soft, so I reused it. Went back together good.

So I got the oil spinner back in. It is a trick getting the chain on the first time around. Used some but not all of the bits in the carb kit. The bowl gasket was not a perfect fit by any means. I ended up using contact cement to stick it right to the bowl... I was worried it wouldn't seal on the sides where the bowl is curved, not straight. Started her up. Not sparking well on the left cyl. Gonna throw a new set of plugs at it.
Best,
Took the first ride on the dream today. The petcock fixed itself. I'm owing that to the rubber swelling up. That's my theory, and I'm sticking to it. It's very stiff, but as long as it doesn't leak, I'm ok with it. I forgot to buy the plugs on my way out of town, so I just sanded the 'lectrode and ground. Ran on two cylinders a little while I was going round in circles. I have limited amounts of time to fool with it in the afternoons. But I am making progress little by little.

Put new plugs in on Sunday. Rode around in circles again. Seemed starved for fuel. Checked flow through petcock. Seemed ok. Took bowl off carb. Was not full by any means. Turned fuel on and flicked floats up and down. Seemed to work ok. Today, started again. Rode around in circles. Ran better. Put the new adj. screws in the carb as well.
Tank was in pretty good shape, but you never know...going to tag her and start puttering around town.
Best,
