Summer once-over on my '04 Summit, what to look for?

[Old-Soul]

frustrating.

Took the day off yesterday and stared tearing down my 265 that's destined for my Model A. Taking things apart is easy and very stress relieving. Mixed with the fact that all the effing snow is melting I kind of have a case of the ****-its regarding my sled.

Lots of sleddin season left..don't give up on the rev yet!!

Ok, sorry I keep coming back to pick your guys' brains but this machine is an enigma.

I've talked to a couple local engine dudes and they're telling me that if I did the "extensions down the holes" test and the one side starts on it's way back up just as the other crosses TDC it's not my crank being out of phase that's my issue. IT would have to be really out of whack to cause these symptoms.

Is there anything else I haven't checked?? Cleaned carbs and changed both pilot and main jets. New plugs/wires/caps (and both plugs have steady blue spark when pulled over). Y pipe is tight and appears to be in good shape. Reeds look intact (is there any way they could kill off a hole like this? Boots are in good shape). Weird thing is we squirted gas into that carb while the machine was running and it made zero difference. RAVE valves shouldn't cause my troubles but I removed and cleaned them anyways. Good compression both sides.

Like I said, I don't like pestering you guys but this really has me beat.

Man, I think you have exhausted every single avenue that I would have checked. Maybe a blockage in the Y pipe? This is a tough one. DESS cord is on correctly and all that other jazz?

 

[Old-Soul]

While I haven't pulled the Y right off (just checked the bolts to make sure they were secure) I guess it could be worth a shot to make sure it's clear. I can't see it being the DESS as that shouldn't effect just one hole...but man who really knows.

 

[summitstef]

This could be a fuel delivery issue as well. No blockages in the fuel lines and both carbs are getting good fuel flow? If you have good spark an everything else is good, maybe the fuel pump packed it in as well or a blockage in the fuel line somewhere or even maybe the pickup in the tank.

 

[Old-Soul]

It's sure acting like a fuel delivery thing but damned if I can find it. But if that were the case you'd think squirting fuel right into the carb would produce some kind of result

Hope you figure this thing out! Very curious as to what you will find

Oh when and if I do I'll be sure to whine/brag on here about it haha

Well I finally emerged from my pit of self-loathing and despair and decided to poke around the sled some more (also been helping some buddies with their cars so that's taken some time up too.)

Pulled the recoil off and dug down into where the engineers decided things like coils and stators should be hidden.

The flywheel is made of two pieces. The "bowl" that the magnets are built into and your flywheel bolts too is two pieces riveted together. Or at least, it's supposed to be. Mine is nearly coming apart as all the rivets are stretched out and the the "bowl" can move back and forth a few degrees. I have a feeling this is related to my timing woes...

Looks like lots of isofux grease in there to from the mag seal eh

sent while I should be drinking tea's

 

[Old-Soul]

Yeah. The further I get into it the rougher my old steed is. Gotta decide how to go ahead with this old clunker now.
