I was out beating the crap out of my savage yesterday and I was getting temp reading around 220-230 at or near the glowplug down inside the head. The top of the head read 170 and the side of the crank case read 180-190, but the exhaust header read 250-370.
When the temp at the glowplug was around 250, it was acting as though it was lean. On a WOT jab of the throttle, it would almost stall. I'd richen it 1/8th turn, then it would be blubbery unless I kept running it hard. For normal putting around and climbing, it was kind of a headache. Which is why I beat the crap out of it. It ran good when ran hard and the temps stayed around 240-250 at the GP.
I'm kind of wondering if it has something to do with my air filter, the blubberyness at midrange. I took the filter off and cleaned it, but I replaced it with a motor saver filter I had laying around that I've never ran. It came with a trade that I had done about 6 months ago. I haven't run it with the MS filter yet. The filter I had on it came with an OS 21 RG.
In general, with this engine, I've not had a reall successful time tuning it. It's the Omega 21 Comp pullstart. When it runs well, it's a pretty good performer. But there's always a little blubber from about 1/3-2/3 throttle. And the weird temp readings I got above kind of threw me.
Anyone have any suggestions on how I can make it through a few hours without a headache with this thing? The XTM 24.7 is looking better all the time... My OS 21 RG in my maxx is really reliable, but it's not a high HP engine, so I don't want to get another one and throw it in my savage. But I would like to get the omega running right.
The Omega has about 3 gallons run through it. I've completely tore it apart, cleaned and sealed the carb, HS needle and backplate about 1/2 gallon ago. I've done that about 3 times on this engine. There's still a lot of pinch left in it as well. I run MHP 20% fuel with an OS #8 plug. I've also checked the fuel tank for leaks and replaced all fuel line (many times).
