Another Day Closer To Freedom!
Yesterday I went up to Seeley Lake to see what new fuel lines and blasting out the carbs with cleaner was gonna do for me. Well what a crappy day, she ran HORRIBLE! All day I tried to tune her up using the Low Speed Adjusters, to no avail. This morning I decided to tear into the carbs and check how the needles were seating, but I never made it that far...
So I mentioned I had changed my fuel lines last week correct? Well they didn't go down without a fight. The fuel they left in my tank was as yellow as beer!
Those lines are nasty! There is no way my fuel could have gotten contaminated by sitting in there for a week. Granted it did rain all week. But I've come to the conclusion that fuel running through the grey lines gets yellow and stale like this and goes back to the tank via the return line. So I cleaned out the entire fuel system this morning, draned the tank, cleaned it, flushed out all fuel lines, blew out the carb lines, cleaned the spinner filter (needed a new gasket, had to make one from a bit larger neoprene gasket but made it through the day). Pute it all back together, reset the carbs to LSA 1 1/4 turns out, and the HSA in the middle (caps are still on, can only turn 1/4 of a turn) Idle was around 1500rpm. went to the gas station, filled her up with premium (a little treat hoping she'd be happy to have fresh fuel in a fresh system). Oh also I forgot to mention I put in a new check valve on my fuel vent, last one was toast, just went to the auto parts store and got a VAC line check valve, looks almost identicle. So now I should be able to keep some fuel pressure in the ole tank.
Well I drove 50 miles to Salmon Lake (MT) and put in the dran plug, unstapped the ol girl blew some air inthe check valve vent, pushed down on the gas tank to prime 'er and choked her till she ran! Okay tunerd it off, put it in the water, fired right up and had plenty of spunk for the short trip to the beach. Parked the truck and went back and once I got on the lake there was just a little hesitation in the mid range. I thought well I'll go turn out those LSAs 1/4...from that point on the mid range only got worse...didn't matter where those LSAs or HSAs were there was just nothing from 2500 rpm to 4500rmp. soon as she hit 4500 she ran like a raped ape, got a full 7000rpm and 50 mph out of her. So right now anything over 4500 rpm is great, but just no power below there.
So I came home and pulled the air box and took her down to the river and back it in still strapped down. I decided to do some power tuning. Fired it up and started turning the LSAs simultaneously...my results? A smooth idle was obtained between 1600 and 2100 rpm with the LSAs ALL THE WAY IN!?
The further out they came the worse she ran...so I put in new plugs, gapped to approx .21. Still no better, old plugs were a nice golden brown, like a butterball turkey on Thanksgiving Day.
So right now I have done the following...
New Fuel Lines
New Check Valve
Cleaned Out Carb With Carb Cleaner (took both sides off, new gaskets)
New Plugs
Adjusted LSAs Anywhere Between 3 Turns and No Turns
Adjusted HSAs Within Range of Factory Cap
And when I give her full throttle she typically bogs for a second then slowly climbs through 2500-4500rpm then takes off like a bull with gas. If I choked it just a little she usually flew threw 3000+ and would nearly throw me off the back. So if anyone out here has one more step for me to try I am ready for it
